A fully integral bridge that is restrained at both ends by the abutments has been proposed to form a monolithic rigid frame structure.
Thus, the feasible horizontal force effect due to an earthquake or vehicle braking is mainly prevented by the end-restraining abutments.
In a recent study, a fully integral bridge with appropriate end-restraining abutment stiffness was derived for a multispan continuous railroad bridge based on linear elastic behavior.
Therefore, this study aims to investigate the nonlinear behavior and seismic capacity of the fully integral bridge and then to assess the appropriate stiffness of the end-restraining abutment to sufficiently resist design earthquake loadings through a rigorous parametric study.
The finite element modeling and analyses are performed using OpenSees.
In order to obtain the force-deflection curves of the models, nonlinear static pushover analysis is performed.
It is confirmed that the fully integral bridge prototype in the study meets the seismic performance criteria specified by Caltrans.
The nonlinear static pushover analysis results reveal that, due to the end-restraining effect of the abutment, the lateral displacement of the fully integral bridge is reduced, and the intermediate piers sustain less lateral force and displacement.
Then, the sectional member forces are well controlled in the intermediate piers by a proper application of the end-restraining abutments.
