Abstract

The use of CFST in building construction has increased significantly in the recent years mainly due to its simple construction sequence and superior structural performance. Therefore, it is necessary to understand their behavior as structural member. Extensive experimental studies about concrete filled steel tubes (CFSTS) have been conducted in past. However experimental results are not sufficient to support the engineering of these components. Advanced numerical techniques are required to simulate their behavior to extend the experimental research and develop predictive tools required for design and evaluation of structural systems. The objective of the present research work is to study the buckling of CFST column with different cross section. In the present research, the non-linear analysis of concrete filled steel tube (CFST) is done using ANSYS WORKBENCH 17 and SAP software. Circular cross sections are studied. It has been found that performance of circular cross section depends on L/D and D/t ratios.
