EARTHQUAKE RESPONSE ANALYSIS OF RIGID FRAMES WITH RHS COLUMNS ALLOWING FOR DEFORMATION OF JOINT PANELS

Abstract

This paper describes the results of earthquake response analysis of rigid frames with RHS columns allowing for deformation of joint panels. The major objective of this analysis is to investigate the inelastic response of member in the frames under strong earthquake ground motions. From the results of the response analysis, maximum story deformation anale of the frames and cumulative plastic deformation of members can be obtained. The effect of energy absorption by joint panels and the influence of vertical earthquake around motions are also discussed in this paper.
