EFFECT OF STRUCTURAL PARAMETERS OF SHEAR PANEL DAMPER ON SEISMIC PERFORMANCE OF MULTI-PIPE INTEGRATED BRIDGE PIER

Abstract

 The purpose of this research is to assess structural parameters such as aspect ratio, plate slenderness parameter and flange web thickness ratio of shear panel damper on the seismic performance of multi-pipe integrated bridge pier originally proposed by Hanshin expressway corporation for further development. In this research, FE analytical model were constructed based on the experimental results for the real scale shear panel damper of the pier. And then cyclic and seismic response analyses for various the structural parameters were carried out to investigate the cyclic behavior and energy absorption performance of the shear panel analytically.
 Based on results of the FE analysis the new relationship of limit shear strain of the shear panel to plate slenderness parameter was proposed. The result of seismic response analysis also concluded the correlation of the structural parameters of the shear panel to the seismic responses.
