Abstract :

This Research aims to study the behavior of axially loaded hollow steel tube concrete–filled steel tube(CFST) columns under monotonic loading using the finite element software ANSYS.12. Modeling accuracy is established by compå results of the Nonlinear Analysis and the Experimental test. It is concluded that the parameters have considerable effect on the behaviour of the columns. The prime factors considered to affect ultimate axial load and corresponding axial shortening under axial compression are cross–sectional area (A), wall thickness of the steel tube (t), strength of in–filled concrete (fcu). Most of the research on concrete–filled steel tube is restricted to a deterministic approach. To gain clear insight into the random properties of circular concrete–filled steel tube, reliability analysis is carried out in the present study. Materials specifications, resistance model, and load models were designed using structural reliability techniques. the reliability of concrete–filled steel tube was investigated using the first–order reliability method(FORM) combined with nonlinear finite element analysis.
