鉛ダンパーを有する免震建物の地震応答解析 : 別置型鉛ダンパーの復元力特性の違いが応答に与える影響について

Abstract

In this paper, the response in the earthquake of the seismic isolated building with the U-shaped lead damper is examined. Effect of the difference of the method which models restoring force characteristics of the damper on the response characteristic of seismic isolation structure is examined by carrying out the numerical analysis, and the features are clarified. It is considered that as a result of the numerical analysis, it is possible that the restoring force characteristics of the U-shaped lead damper estimates the necessary response by modeling at the simple bi-linear, for the design at the enough accuracy.
