多層筋違付架構の動的応答性状に関する研究 (その1)

Abstract

Dynamic response analysis of a multi-story braced frame was conducted. It was assumedthat the structure was composed of an open frame and a braced wall, that the hysteretic charac-teristics of the open frame was bi-linear and that the restoring forces of braces were predicted bythe formulae proposed by the authors. The axial force variation and the elastic elongation ofwall-side columns were also taken into account.The results of the response analysis show that the structure which is designed to be muchdependent on braces may catch a severe damage in certain story because of the deteriorativeproperty of the hysteretic characteristics of braces.
