DAMAGE SIMULATION ANALYSIS ON STRUCTURE LIMITING EXCESSIVE DISPLACEMENT BY THE DIFFERENT DESIGN SEISMIC LOADS

Abstract

 The purpose of this study is to reveal the relation between yield strength of structure limiting excessive displacement and the load that shear cracks occur on the abutment. Especially, the relation of design seismic load and damage form are focused on. From the analytical result, stiffness changes radically when the load is 3798kN because reinforcing bar of displacement restriction structure is yield. Secondary, as the seismic load is decrease, the number of the shear cracks increase in the excessive displacement stopper. Finally, it would be necessary to lift up the height of structure limiting excessive displacement in order to damage the structure limiting excessive displacement before the shear cracks occur in the abutment.
