Abstract

Response of structural components like beams have been studied by different methods. One of the methods which is widely used is experimental testing. But since it provides actual response, it can be quite costly and time consuming. However, finite element analysis has been used a lot due to capabilities of computer hardware and software. The use of software to model structural components is cost effective and much faster.
In this study, ABAQUS was used for numerical simulation of a concrete filled steel tube (CFST) beam and the effect of width/thickness ratio, yield strength of steel tube, compressive strength of concrete and the stiffness on the moment capacity of the CFST beam were studied.
The simulation shows good agreement with the experimental results. After validation of simulation, the parametric study on the moment strength of the beam was carried out to predict the simple equations for maximum moment capacity of CFST beam. It was observed that the capacity of the beam was governed by the steel tube strength.
