EVALUATION OF THE DEFORMATION PERFORMANCE OF RC PIER MODELS WITH ADDITIONNAL REINFORCING BARS TO PROVIDE THE DIFFERENCE BETWEEN THE YIELD STRENGTH AND MAXIMUM HORIZONTAL STRENGTH OF THE BRIDGE PIERS

Abstract

 As a seismic resistance measure for road bridges, a design method that selectively ruptures the plate retaining bolts of rubber bearings when the action exceeds the design seismic motion level is investigated. To realize this design method, reinforcing bars are added to create the difference between the yield capacity and the maximum horizontal capacity of RC piers. In this study, the deformation performance of this RC pier model is evaluated based on the results of cyclic loading tests, and it is confirmed that the assumed damage scenario can be realized.
