Abstract

In this paper, firstly, we investigate the seismic behavior of a typical steel truss arch, and have found that it may suffer a risk of collapse. Then for the retrofit of existing large span truss structures, a passive seismic control system using Buckling-Restrained Members, abbreviated as BRM, is suggested to enhance the earthquake resistant capacity. Through the elasto-plastic earthquake response analyses, the effect of BRM on reducing the structural seismic responses is confirmed. Finally, based on the result of parametric study, the design base-shear coefficient for BRM and the proper location for incorporating BRM are proposed for this kind of steel truss arch.
