PUSHOVER ANALYSIS AND ITS APPLICATION IN CONCRETE-FILLED RECTANGULAR STEEL TUBULAR FRAME

Ust Inner

Abstract

This paper reviews the method of the pushover analysis.Pushover analysis of a concrete-filled rectangular steel tubular frame structure is done using ETABS analysis program.The analysis and test results show that pushover analysis can confirm structure failure mechanism and estimate structural failure weakness;and a good agreement is reached between the base shear-top displacement curve by pushover analysis and available experimental results. Besides P-△ effect has a greater influence on pushover analysis.
