| Abstract: | The 3 D finite element model for concrete filled square steel tubular column axially compressed is established by large scale finite element software ABAQUS,in which coupled thermo mechanical nonlinear analysis has been made.Furthermore,the influence of different paramenters on fire resistance is calculated by parametric approaches and concerning regression equation is obtained. |
