      <title>Ultimate bearing capacity and multi-scale optimization design of a novel palm-shaped joint in steel structures</title>
      <link>https://trid.trb.org/View/2712955</link>
      <description><![CDATA[To investigate the mechanical properties and ultimate bearing capacity of complex steel structural systems, this study examines a novel palm-shaped joint used in the spatial grid and truss composite structure of the Guangzhou Baiyun International Airport Phase III Hangar Project. Axial compression tests were carried out on a 1:3 scaled model, complemented by finite element simulations conducted in Abaqus. The results demonstrate that the joint failure is primarily due to out-of-plane buckling of specific steel plates, with an ultimate bearing capacity approximately 3.1 times the design load, indicating a considerable safety reserve. The tube wall thickness and overlap ratio are identified as key factors affecting joint strength, whereas the inclination angle between the supporting member and the chord shows negligible influence. An improved design formula is proposed based on parametric studies, offering significantly enhanced accuracy over current design codes. Additionally, a multi-scale optimization design scheme incorporating longitudinal stiffeners is introduced, which leads to a 13.7 % reduction in maximum stress and a 39.55 % decrease in displacement under ultimate loading conditions, markedly improving the joint’s mechanical performance. The findings offer valuable insights for the optimized design of complex joint systems in contemporary steel structures.]]></description>

      <title>Steel Corrosion in Underground Transportation Infrastructure</title>
      <link>https://trid.trb.org/View/2698481</link>
      <description><![CDATA[Corrosion of buried steel, a critical component of American transportation infrastructure, remains one of the most insidious challenges due to the uncertainty associated with its estimates. Predicting when and how this corrosion happens is very difficult. This uncertainty grows exponentially with time, making corrosion estimation in the long term even more challenging, especially with buried steel and steel structures, which cannot even be monitored visually. While significant advancement has been made to understand the effect of the various corrosion parameters on soil corrosivity, there is a lack of a comprehensive understanding of how these factors collectively contribute to corrosion as they vary simultaneously and continuously with time. This project evaluates soil resistivity and corrosivity in controlled, constant conditions, considering the various key parameters that contribute to corrosion of buried steel. The project involved devising a new experimental protocol, developing and implementing a comprehensive experimental program by varying one testing parameter at a time. The results of the testing program showed the potential of the experimental approach to provide the necessary data to develop empirical prediction models for soil resistivity. Additionally, a new experimental method was piloted for this project to capture the variation in soil resistivity in a continuously varying environment. Finally, the researchers compiled a large digital database of real-world corrosion measurements and site information. Using advanced data analysis techniques, they created a model that can help predict corrosion in buried steel structures and estimate the level of uncertainty in those predictions. Better predictions of corrosion can help engineers and infrastructure managers identify risks earlier, plan maintenance more effectively, and extend the life of critical infrastructure such as pipelines, bridges, and transportation systems, therefore helping to reduce costly failures, improve safety, and support more reliable systems.]]></description>

      <title>Prediction of shear capacity for PBL connectors in concrete using visualization-based machine learning</title>
      <link>https://trid.trb.org/View/2685417</link>
      <description><![CDATA[Accurately predicting the ultimate shear capacity of perfobond rib (PBL) connectors is of great significance for the design of steel–concrete composite structures. This study predicted the ultimate shear capacity of PBL using machine learning (ML) methods. Initially, a dataset comprising 233 sets of PBL push-out test data was established. To enhance data quality, an Isolation Forest was used to identify and eliminate outliers from the dataset. Subsequently, four ML models—XGBoost, DT, RF, and ANN—were trained on this dataset to predict the ultimate shear capacity of PBL. By comparing and analyzing the prediction results, XGBoost demonstrated the best predictive performance with an R2 value of 0.97, outperforming other models. Then, a visual analysis, including SHAP and PDP, was conducted on the XGBoost model, revealing the contribution levels of different features to the predicted values. The analysis found that the number of perforated holes (n) had the greatest impact. Moreover, based on the analysis of visualizations, recommended ranges of values for the input features are provided to maximize the ultimate shear capacity of the PBL connectors. In comparison with traditional formulas, the trained ML models exhibit superior accuracy. The MAE of XGBoost is approximately 10% of that of the traditional formulas, and its RMSE value is less than 20% of those.]]></description>

      <title>Deep Learning–Based Digital Image Correlation for Fatigue Crack  Characterization in Steel Structures
</title>
      <link>https://trid.trb.org/View/2703927</link>
      <description><![CDATA[This proposal presents a strategic approach to improving transportation safety through the advancement of deep learning–based Digital Image Correlation (DIC) for fatigue crack characterization in steel structural components. With aging transportation infrastructure and increasing cumulative traffic loading, fatigue-related deterioration in steel bridges and related systems presents ongoing safety risks. Accurate measurement of crack-induced displacement fields is critical for reliable structural assessment and informed maintenance decisions. The primary objectives of this proposal are to advance artificial intelligence (AI)-driven DIC methods beyond the limitations of conventional correlation-based approaches by enabling sub-pixel displacement learning through synthetic data generation, incorporating physics-informed modeling of crack-induced displacement discontinuities, and supporting high-resolution analysis of large image regions without loss of spatial detail. The methodology involves grayscale synthetic speckle data generation for sub-pixel displacement learning, mechanics-based displacement field modeling using finite element simulations, and development of an attention-enhanced deep learning architecture for full-field displacement prediction. Experimental validation against commercial DIC systems will establish a transferable methodology supporting safer fatigue crack evaluation practices.

      <title>Evaluation of the Performance of Bridge Steel Pedestals under Seismic Loads</title>
      <link>https://trid.trb.org/View/2235303</link>
      <description><![CDATA[Over 50 bridges in Georgia have been elevated using steel pedestals as a cost-effective means to increase the clearance height and to reduce the likelihood of impact damage from over-height vehicles. Steel pedestals are W-shape members that resemble stub columns and transfer loads from the bridge deck to the substructure. While steel pedestals perform similar in function as bearings which have been vulnerable components in past earthquakes due to lack of deformation capacity and potential instability, steel pedestals may also prove to be vulnerable components for similar reasons. To evaluate the behavior of steel pedestals, an experimental study is conducted and the results from 33 1/2" tall steel pedestals are compared to past experimental studies that showed the results of cyclic quasi-static loading on 19" short steel pedestals. The experimental test setup consists of a full-scale two-beam 40' span bridge system with steel pedestals subjected to low level (cyclic quasi-static) and high level (peak) loads. Results from the experimental testing are presented in terms of load-deflection hysteretic behavior and effective stiffness exhibited by the system. Different configurations for the post-installed anchor bolt connection elements to the reinforced concrete pier cap are tested and compared. Future analytical studies will use a bridge model to reveal the most vulnerable aspects of steel pedestals and provide recommendations for appropriate connection details for ensuring adequate seismic performance.]]></description>

      <title>Seismic Performance Analysis of Railway Station Roofs under Complex Climatic Conditions in Cold Regions</title>
      <link>https://trid.trb.org/View/2632704</link>
      <description><![CDATA[High-speed railway stations with long-span steel structures are vulnerable to severe climatic conditions in cold regions, particularly when temperature differences, snow loads, and seismic events occur concurrently. This study develops a finite-element model of a large-span steel roof in a high-seismic, cold climate zone to assess the combined effects of extreme temperature differences, snow loads, and earthquakes. Results reveal that under coupled extreme loading, key roof components experience significant stress increases, and midspan vertical displacements exceed 450 mm—nearly double the design deflection limit of 240 mm. These deformations pose serious structural risks, including excessive stress concentration at critical joints and an increased likelihood of progressive collapse, particularly in the midspan regions. The findings highlight the need to revise current design codes to consider load combinations typical in cold-seismic environments and propose engineering strategies, such as enhanced joint design and snow load monitoring systems, to improve structural resilience.]]></description>

      <title>Stability characteristics of steel cylinders under large surcharges in deep soft foundations reinforced with stone columns</title>
      <link>https://trid.trb.org/View/2627069</link>
      <description><![CDATA[The steel cylinder has significant potential for marine engineering applications. The deformation and stability characteristics of steel cylinders with deep soft foundations under a large surcharge of 300 kPa remain insufficiently explored. In this work with the use of a case study, the stability characteristics of steel cylinders with deep soft foundations under 300 kPa surcharge are examined during the dry construction and surcharge periods. The results indicate that rotational dislocation towards the land side occurs during both the dry construction and surcharge periods. The pore water pressure remains stable during the dry construction period but significantly fluctuates during the surcharge period, and excess pore water pressure is generated. The maximum settlement occurs in the mud layer during both the dry construction and surcharge periods. The hoop tensile strain response of the steel cylinder varies along the depth direction during the surcharge period but remains within the allowable range of the material. Furthermore, variations in the pile axial force, shear force, and pile‒soil stress ratio indicate that the stone columns play crucial roles in reducing the lateral earth pressure and enhancing the foundation bearing capacity. These findings provide new insights into the application of steel cylinders under 300 kPa surcharges.]]></description>

      <title>Process-Based Carbon Emission Assessment of the Cable-Stayed Anchored Cantilever Construction Method: A Case Study of a 600-Meter-Scale Arch Bridge</title>
      <link>https://trid.trb.org/View/2650623</link>
      <description><![CDATA[There is a growing need to quantify carbon emissions from bridge construction, while the field lacks systematic modeling approaches tailored to specific construction methods, especially in arch bridge engineering. This study addresses this gap by focusing on a concrete-filled steel tube (CFST) arch bridge with a main span 600 meters, constructed using the cable-stayed anchored cantilever method. A comprehensive research framework is established, integrating sub-project decomposition, carbon emission factor methodology, machine learning prediction, SHAP (SHapley Additive exPlanations)-based mechanism interpretation. A dynamic carbon emission quantification model is developed, while a predictive model is constructed using machine learning algorithms. The results reveal that the construction of arch foundations and arch ribs are the two most carbon-intensive stages, with concrete pouring and steel hoisting operations playing a dominant role in emission generation. A multi-dimensional emission reduction strategy is further proposed, including structural design optimization, low-carbon material substitution, and construction process improvements. The study confirms the low-carbon advantage of the cable-stayed anchored cantilever method, which minimizes temporary material usage, with the Cable Hoisting and Cantilever systems contributing only 8% to the total construction emissions. This study offers theoretical support and critical evidence for low-carbon decision-making that aligns with safety requirements of the cable-stayed anchored cantilever method in long-span arch bridges.]]></description>

      <title>Shaking-table tests on a steel cable-stayed bridge with spatial irregular pylons</title>
      <link>https://trid.trb.org/View/2601241</link>
      <description><![CDATA[Irregular cable-stayed bridges exhibit more pronounced spatial coupling effects under seismic loading, making them more susceptible to damage during earthquakes. To investigate this effect, this study conducted a 1/40 scale shaking table test based on a spatially irregular steel cable-stayed bridge with a main span of 639 m. The bridge features two pylons of unequal height with curved, irregular forms, exhibiting spatial torsional characteristics. First, a scaled model of the irregular cable-stayed bridge was designed, and a multi-subarray shaking table test was conducted. The study investigated the effects of seismic excitation direction, amplitude, and different seismic wave characteristics on the seismic response of the irregular cable-stayed bridge. The results indicate that the seismic response of the irregular cable-stayed bridge is significantly influenced by the vertical vibration mode. The impact of the vertical mode on the longitudinal seismic response is greater than that on the transverse response, with a quantitative impact ratio reaching up to 58.8 %. The bridge deck near the irregular pylon exhibits asymmetric vertical displacement responses, with the maximum difference reaching 7 %. The impact of pulse-type seismic motion on the bridge is more pronounced. Under the excitation of the Chi-Chi earthquake wave, the amplification factor of the acceleration response of the bridge tower in the longitudinal direction can reach 5.48. In addition, irregular cable-stayed bridge pylons can exhibit two spatial torsion modes under seismic excitation: Torsion mode 1 increases the spatial torsion angle, enhancing the pylon's spatial irregularity, while Torsion mode 2 reduces the irregularity. The results of the shaking table test can provide relevant theoretical basis and data support for the seismic behavior of irregular steel cable-stayed bridges.]]></description>

      <title>Experimental and numerical study on the fire resistance behavior of steel truss girder structure in double deck suspension bridges</title>
      <link>https://trid.trb.org/View/2584362</link>
      <description><![CDATA[To investigate the fire resistance behavior of the double deck steel truss suspension bridge, two scaled models of double deck steel truss segment with a similarity ratio of 1:10 were designed and fabricated based on a large-span suspension bridge. The fire resistance tests of scale models with and without fire protection were conducted under load conditions, and the heat release rate of fire source was determined as 50 MW. The deformation characteristics and temperature distribution of the scale models under different fire protection schemes were studied, and the fire resistance behavior of the double deck steel truss was preliminarily revealed. The results showed that the bridge deck of experimental model without fire protection exhibited the local depression, and the transverse beams and web members appeared bending deformation and local bucking. In addition, the web member exhibited a significant temperature gradient across the section, with the maximum temperature on the fire side reaching 1007 ℃, while the temperature of the back side was only 336.5 ℃, making it more prone to local buckling. The temperature of main components of the model with fire protection was lower than that without fire protection. The maximum temperatures of the web member, diaphragms plate and bridge deck of the experimental model without fire protection were 1007 ℃, 654 ℃ and 712 ℃, respectively. However, the temperatures of each component under the protection of fireproof materials were reduced by 29.0 %, 52.3 % and 45.4 %, respectively. The steel truss girder model was characterized by the failure of components, resulting in irreversible deformations. The proposed fire protection scheme proved to be effective, achieving commendable fire resistance and thermal insulation performance.]]></description>

      <title>FRP-based reinforcement coatings of steel with application prospects in ships and offshore structures: a review</title>
      <link>https://trid.trb.org/View/2559107</link>
      <description><![CDATA[Latest research on novel FRP-based anti-corrosion structural coatings (for enhancing structural capacity and strengthening the coating layer) is discussed with application prospects for ships and offshore structures. In the marine environment, structures constantly face corrosion and fatigue cracks. Combining this with high operational and wave loads, it might cause a structural collapse. Recently, polymer composites have been studied for possible reinforcement, especially for steel structures in civil engineering. It is important to assess their effectiveness and review of research on the fatigue, tensile, buckling, and debonding properties of fibre-based structural coatings is given and summarised. Most research focused on carbon fibre reinforced composites. Resins matrices other than epoxy, behaviour on corroded steel, ply orientation, and pre-stress level are still untapped adequately. Similarly, another types of fibres than carbon and their hybrids are still insufficiently examined. Although such research direction is promising, the need for future research is highlighted and given in detail.]]></description>

      <title>Measurement of Adhesion Properties Between Topcoat Paint and Metallized/Galvanized Steel with Surface Energy Measurement Equipment</title>
      <link>https://trid.trb.org/View/2596539</link>
      <description><![CDATA[The objectives of this research project are: (1) Compare the adhesion properties of NEPCOAT-approved topcoat paint over metallized or galvanized steel. Use “surface-energy” measuring technique to characterize the wetting properties of the liquid paint on the profiled zinc surfaces. Explore correlation between the adhesive strength and the liquid paint wetting properties. As control the adhesion properties of topcoat paint over zinc primer painted steel substrates will also be measured. (2) Investigate various factors affecting the adhesion of topcoat paint over galvanizing. (3) Report and recommend practices that produce the best adhesion of NEPCOAT-approved topcoat paints over metallized and particularly galvanized steel surfaces. The authors prepared four different types of test panels coated with five different commercial paint systems. The paint systems include four systems adapted from the NEPCOAT list of intermediate and top paints qualified for bare steel, and one system of epoxy sealer for metallized surface. Four types of substrates were used for fabricating the test panels: (1) galvanized steel with mechanical grinding to produce rough surface, (2) galvanized steel with blast profiling to produce rough surface, (3) galvanized steel stored indoors for two weeks before blast profiling and painting, and (4) metallized steel with inherent roughness due to the thermal spray process. The authors recorded, as a function of time, the contact angle of droplets of freshly prepared liquid paints on the replicas of the substrate used for spray painting. The cured test panels were subject to pull-off strength tests according to the ASTM D4541 standard, and the X-cut tape tests according to Method A of ASTM D3359 standard. Images of the pull-off test break surfaces were photographed and examined. The authors analyzed the correlation between the pull-off strengths and the contact angles. The correlation provided insight on the relative adhesive strengths of the different paint-substrate pairs. The authors concluded that (1) the NEPCOAT paints could be used for galvanized and metallized steel to obtain comparable adhesion performance as that of the zinc-rich organic primer coated steel, (2) although the NEPCOAT intermediate paint on the metallized surface has adequate pull-off strength to pass the inspection, it is highly recommended that the state DOT specification of the use of sealant is strictly followed, (3) although the exposure to atmosphere after galvanizing is commonly recognized as a problem for paint adhesion, the authors found that a time delay of two weeks between galvanizing and profiling/painting is permissible if the galvanized steel is stored in the normal indoor dry atmosphere, (4) the authors think a refined quantitative correlation between pull-off strength and contact angle could be useful for optimizing the paint-to-substrate match.]]></description>

      <description><![CDATA[The article deals with the peculiarities of designing steel girder constructions according to the first group of limiting states, according to the criterion of bearing capacity and stability of the structure. The paper analyses basic calculation cases of steel girder wall stability loss with estimation of their causes, considers possible solutions of steel girder wall stability using traditional methods as well as application of new structural composite materials with estimation of their possible effect on improving girder wall stability. An algorithm for the calculation of girder constructions is compiled in this article, and the load-bearing capacity and stability of the design case of a steel I-beam is calculated. The main insufficient stability zones of the beam wall in case of uniformly distributed load along the whole length of the beam are determined, for the considered case a rational possible form of composite plates used as an alternative structural solution for increasing the stability of the hybrid beam wall is determined.]]></description>

      <title>Non-uniform temperature fields and debonding of a long-span CFST arch bridge under coupled environmental actions</title>
      <link>https://trid.trb.org/View/2588072</link>
      <description><![CDATA[To investigate the temperature field distribution characteristics and delamination mechanisms in long-span concrete-filled steel tubular (CFST) arch bridges within mountainous regions, comprehensive in-situ measurements were performed on the Chongqing Shuangbao Bridge. A sophisticated temperature field model for CFST arch bridges under solar radiation, ambient temperature variations, and cement hydration thermal effects was developed. Furthermore, an innovative theoretical framework integrating engineering mechanics with the temperature field model was established to analyze interfacial delamination behaviors. Experimental and theoretical analyses yielded several significant findings: (1) During the hydration exothermic phase, the temperature field at concrete center exhibited a tri-linear distribution pattern (characterized by rapid initial rise, subsequent decline, and final stabilization), with the ascending rate significantly exceeding the descending rate; temperatures exceeded 50°C between 25 and 73 h post-placement. (2) The external steel tube temperature demonstrated sinusoidal diurnal variations during and post-hydration, closely correlating with ambient temperature fluctuations; after hydration, concrete temperatures also followed sinusoidal diurnal distributions, with amplitudes increasing proportionally to radial distance from the center. (3) A pronounced radial temperature gradient from center to surface manifested during hydration, reaching a maximum differential of 40°C; the temperature gradients substantially decreased to 7°C after hydration. (4) Longitudinal stress differentials between the interface steel tube and concrete measured 42.5 MPa (sun-exposed side) and 74.2 MPa (shadowed side), while radial stress differentials were −1.37 MPa and −0.34 MPa, respectively. (5) The temperature field model demonstrated a tri-linear distribution pattern with an effective influence depth of D/8 to D/4 (where D represents steel tube diameter); the temperature constant exhibited significant temporal dependency on environmental conditions and hydration heat evolution. (6) Although longitudinal relative slip occurred at the steel-concrete interface during placement, no void was detected.]]></description>
