In the present study, the behavior of Conventional Concrete (CC), Light Weight Concrete (LWC) and Self Compacting Concrete (SCC) Filled Steel Tube (CFST) columns under Monotonic ans Cyclic loading has been tested. The experimental investigations are carried out for 54 specimens that includes 18 specimens filled with Conventional concrete, 18 specimens filled with Light weight concrete and 18 specimens filled with Self-compacting concrete (SCC) of grade M20, M30 and M40 with different L/D ratios using Tauguhi approach due to monotonic loading and Cyclic loading . It is found that the capacity of buckling load and deformations are obtained from testing under cyclic loading, the buckling or ultimate load for CFST columns in fill as SCC are higher compare to CC infill by2.2% - 4.5% for cyclic loading. Buckling load capacity of SCC infill CFST columns is more than LWC infill CFST columns about 4.7% - 7.0% for Cyclic loading. As per the results Buckling load capacity for CFST column with higher grade infill more effective in Cyclic loading and verified and validated using Finite element software ABAQUS6.10.1
