The best-performing XGBoost model achieved performance metrics of R2 = 0.964, MAE = 41.318 kN, RMSE = 56.760 kN, and MAPE = 14.228%. The superior reliability of the XGBoost ensemble model was further validated through comparisons with current design codes and existing models. As ML-based models are typically black-box models, the SHapley Additive exPlanations (SHAP) method was employed to explicitly link the predicted output to the inputs. Based on SHAP results, confining stress (CS), depth of shear key (D), compressive strength of concrete (fcu), total height of joints (H), and height of flat part (Hsm) recognized as the crucial parameters affecting ultimate load.]]> Wed, 27 Mar 2024 11:51:14 GMT https://trid.trb.org/View/2317633 A critical review on shear performance of joints in precast Ultra-High-Performance Concrete (UHPC) segmental bridges https://trid.trb.org/View/2307668 Tue, 26 Mar 2024 16:02:42 GMT https://trid.trb.org/View/2307668 Evaluation of Thin Polymer Overlays for Bridge Decks https://trid.trb.org/View/2344941 Mon, 25 Mar 2024 09:55:21 GMT https://trid.trb.org/View/2344941 Energy-based time equivalent method for evaluating the fire resistance of timber–concrete composite structures exposed to travelling fires https://trid.trb.org/View/2348202 Mon, 25 Mar 2024 09:54:24 GMT https://trid.trb.org/View/2348202 Research on the purification efficiency and mechanism for road runoff pollutants in pervious concrete with recycled aggregates https://trid.trb.org/View/2337910 Fri, 22 Mar 2024 17:05:24 GMT https://trid.trb.org/View/2337910 Applicability of available NDT methods for damage detection in concrete elements reinforced or strengthened with FRP https://trid.trb.org/View/2325891 Fri, 22 Mar 2024 17:04:53 GMT https://trid.trb.org/View/2325891 Evaluation of minimum flexural reinforcement for precast prestressed concrete NEXT beam bridges https://trid.trb.org/View/2325890 Fri, 22 Mar 2024 17:04:53 GMT https://trid.trb.org/View/2325890 Ultra-High Performance Concrete Reinforced with Multi-Scale Hybrid Fibers and Its Durability-Related Properties: Final Report https://trid.trb.org/View/2352880 Thu, 21 Mar 2024 13:24:06 GMT https://trid.trb.org/View/2352880 Practices for Maintaining and Resurfacing Existing Composite Pavements https://trid.trb.org/View/2352891 Thu, 21 Mar 2024 13:24:06 GMT https://trid.trb.org/View/2352891 Flexural Behavior and Model of Curved Bolt Connections with UHPC Grout and CFRP Tendons for Prefabricated Concrete Panels https://trid.trb.org/View/2342153 Wed, 20 Mar 2024 17:10:07 GMT https://trid.trb.org/View/2342153 A Strut-and-Tie Model Approach to Design Precast Column-to-Pile Shaft Member Socket Connections against Prying-Action Failure https://trid.trb.org/View/2347331 Wed, 20 Mar 2024 17:10:07 GMT https://trid.trb.org/View/2347331 Roller Compacted Concrete Shoulders https://trid.trb.org/View/2353421 Wed, 20 Mar 2024 11:23:39 GMT https://trid.trb.org/View/2353421 Develop and Field Test Non-Proprietary Ultra-High Performance Concrete for New Bridge Decks https://trid.trb.org/View/2353419 Wed, 20 Mar 2024 11:02:02 GMT https://trid.trb.org/View/2353419 Characterizing the regional variation of ballast particles’ movement during the increase of local void in ballast bed https://trid.trb.org/View/2337384 Wed, 20 Mar 2024 10:12:17 GMT https://trid.trb.org/View/2337384
