Study on Behaviour of Axially Loaded Concrete Filled Cold Formed Steel Tube

Pavithra K, Dr K. Aarthi Karmegam, Anitha G

Abstract


Cold Formed Steel becomes a new trend in construction material. It tends to study the behavior of cold formed steel tube provided with concrete core inside, when loaded axially. SCCM 30 grade of concrete is used as infill within Cold Formed Steel Tube (cfst) having different Diameter/thickness (D/t) ratio but with same length and thickness. cfst with and without concrete infill are modeled and analysed using ABAQUS software. The Ultimate load carrying capacities of cfst with and without infill are calculated using ABAQUS and compared with AISC and Eurocode 4 results. Load carrying capacities of cfst increases when D/t ratio increases. Maximum principal stress, Maximum Deflection, Buckling load obtained from FEA analysis are tabulated and plotted. Ultimate load carrying capacities of infilled CFST found are about 1.65 times higher than hollow CFST columns.
