Analysis of ABC Bridge Column-to-Footing Joints with Recessed Splice Sleeve Connectors

The use of precast concrete in bridge construction has been abundant in recent years because of its efficiency and superior quality control. Precast components are connected at the bridge site to reduce construction time and traffic disturbance. The Grouted Splice Sleeve (GSS) connection provides good bending moment resistance between precast reinforced concrete (RC) components. This connection type has been widely employed in non-seismic areas. The use of this connection in moderate or high seismic zones has been explored and proposed for medium-size highway bridges. It is essential to propose a numerical modeling technique at the local and global level with the proposed connection type. The primary goal of this project is to compare the computational model to experimental results under cyclic quasi-static loading; the computational model is then used to generate the structural response of a bridge bent under seismic loading. Using existing material models and a forced-based beam-column fiber element that accounts for fatigue, bar-slip, purposeful debonding, and plastic hinge length, a computer model capable of predicting structural response under cyclic loading is constructed. The computational model is subsequently utilized to calculate the seismic response of a three-column bridge bent to near-field and far-field earthquakes in terms of overall maximum drift ratio and drift ratio at the maximum level of seismic demand.
