Abstract

Abstract

The overall buckling behavior of high strength steel columns with nominal yield strength more than 460 MPa was improved a lot compared with the ordinary strength steel columns.The effect of the initial geometrical imperfection and the residual stress on the buckling strength of high strength steel columns was analyzed by using finite element analysis(FEA)method,as well as the change of sensitivity to the initial imperfection.Based on the parameter analysis,including the initial imperfection and the steel strength,it showed that with the increase of the steel strength,the degree of the sensitivity to initial imperfections became lower,especially for the residual stress.Besides,the effect of the imperfection significantly correlated with the slenderness ratio of columns.Finally,the characteristics and advantages of the overall buckling behavior of high strength steel columns were revealed.
- high strength steel,
- overall buckling,
- initial imperfection,
