The ultimate load, load-deflection profile and strain distribution of FCS wall subjected to axial load are obtained. The effects of various slenderness ratio of FCS walls strengthened with DSC on its structural behavior are obtained. The ultimate shear load of FCS walls under push off load test is obtained. FCS walls with DSC attained higher ultimate load and composite action compared to walls with SSC. FCS wall strengthened with DSC is found to behave in a partially composite manner.
