Relative study on concrete filled square and circular steel tubular columns – Using ANSYS for mathematical analysis

Abstract This study evaluates the Concrete filled steel tubular sections (CFST) which is chosen based-on the features of its high capacity, economic, fire resistant and the better seismic act than steel structures. It utilizes the gain of both concrete and steel; it is preferred for its large energy inclusion capacity and degradation due to lower strength. CFST uses Steel tubes structures have sections thinner which are compared with normal columns made of steel. But members get deteriorated owing to environmental factors like ageing and corrosion. Under thought of these feasibilities a relative study has been made between square and circular section for different concrete mixes Nominal concrete (NC), Recycled aggregate concrete (RAC), high performance concrete (HPC)). The effectiveness and act regarding Stress strain, load deflection behavior, collapse pattern are studied in investigational models and resemblance with mathematical model which is done in ANSYS workbench module. In order to avoid degradation due to environmental effects Anti-corrosion agent is used while fabrication.
