摘要: This paper presents an accurate nonlinear finite element model for the behaviour and design of axially loaded concrete-filled square hollow section (SHS) rectangular (RHS) steel tube columns. The material models confined concrete tubes were carefully modeled in analysis. column strengths load-axial shortening curves evaluated. results obtained from analysis verified against experimental results. An extensive parametric study was conducted to investigate effects different cross-section geometries on strength SHS RHS over a wide range cube ranged 30 110 MPa. overall depth tube-to-plate thickness ratio 10 40 covering compact sections. predicted compared with calculated using American, Australian European specifications. Based study, it is found that American Specifications Standards are conservative, while Code accurate, except columns having 40.
