Abstract
This study deals with the dynamic Elasto-plastic analysis considering a member buckling and damage-control structures such as partial cylindrical aluminum alloy truss wall structures induced by the plastic elongation of the steel bolt within the joint connection. The purpose of this study is to investigate the dynamic collapse mechanism within the joint connection bolt tensile collapse type structure system caused by the bolt plastic elongation due to an axial tension stress. The effect of the member buckling and the yield elongation of the steel bolt on the seismic response of the out of the plane is shown in comparison with the response of the plane of the wall structure subjected to the plane direction horizontal earthquake motions. The earthquake evaluation method is also proposed considering the dynamic collapse mechanism. A validity of the proposed method is shown by means of the accuracy between the analysis and the estimation.
