Application of Low Yield Stress Steel to K-braced Frame with Hysteretic Damper

Abstract

A new hysteretic damper installed in K-braced frame using low yield stress steel is presented. The mechanism, restoring force characteristics and energy absorbing capacity of the proposed K-braced frame are examined by cyclic loading tests of ( hysteretic damper and model frame ) and elasto-plastic large deformation finite element analyses of the model frame. Through this investigation, it is clarified that the present K-braced frame has very good characteristics as a damper for building frames.
