Abstract EN
This paper aims to evaluate the impact interaction between the abutment and the girder subjected to nonuniform seismic excitation.
An impact model based on tests is presented by taking material properties of the backfill of the abutment into consideration.
The conditional simulation is performed to investigate the spatial variation of earthquake ground motions.
A two-span continuous steel box girder bridge is taken as the example to analyze and assess the pounding interaction between the abutment and the girder.
The detailed nonlinear finite element (FE) model is established and the steel girder and the reinforced concrete piers are modeled by nonlinear fiber elements.
The pounding element of the abutment is simulated by using a trilinear compression gap element.
The elastic-perfectly plastic element is used to model the nonlinear rubber bearings.
The comparisons of the pounding forces, the shear forces of the nonlinear bearings, the moments of reinforced concrete piers, and the axial pounding stresses of the steel girder are studied.
The made observations indicate that the nonuniform excitation for multisupport bridge is imperative in the analysis and evaluation of the pounding effects of the bridges.
