BUCKLING ANALYSIS OF CONCRETE FILLED STEEL TUBE COLUMNS

The use of CFST in building construction has increased sig nificantly in the recent years mainly due to its simple construction sequence and superior structural perform ance. Therefore,it is necessary to understand their behavior as structural member. Extensive experiment al 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 technique s are required to simulate their behavior to extend the experimental research and develop predictive tool s 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,th e 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 depend s on L/D and D/t ratios. https://www.ijiert.org/paper-details?paper_id=14114
