R・O型弾塑性建築架構の応答解析

Abstract

In the aseismic design of middle or short height structures, we must take into considerationmore than in that of high rise building, because of their frequency characteristics, such as structure-foundation interaction, strong plastic behavior, initial gravity effects, combined force interaction etc.The detailed response analysis of complex structural models with bilinear hysteretic local jointsneglecting structure-foundation interaction was studied considering the interaction between momentand axial force of these fixed local joints in our previous paper.The object of this research is to establish a method of dynamic analysis of inelastic frame struc-tures composed of the members with Ramberg-Osgood type hysteretic characteristics consideringthe above interaction effects. Three-story, single bay undamped frame structural models loadedat the midspan of each girder subjected to the S82°E component of the 1933, Vernon earthquakeaccelerogram are analyzed and some interesting results are obtained.
