In this study present the results of an analytical aimed to develop and study the axial load bearing performance of damaged columns using cast-in-situ (HCP) Hybrid Composite Panels. The effectiveness of prefabricated hybrid Composite plates (HCPs) as a seismic retrofitting solution for damaged interior RC beam- column joints is analytically studied. HCP is composed of a thin plate made of strain hardening cementation composite (SHCC) reinforced with CFRP sheets/laminates. Two full-scale severely damaged interior beam-column joints are retrofitted using two different configuration of HCPs. The effectiveness of these retrofitting solutions mainly in terms of hysteretic response, dissipated energy. Degradation of secant stiffness, displacement ductility and failure modes are compared to Their virgin states. According to these criteria, both solutions resulted in superior responses regarding the Ones registered in their virgin states. To study the axial load bearing performance of reinforced column under various deficiencies - 20%,40%, 60%... parameters taken for study are different deficiencies of the columns, number of layers and number of bolts and their pattern output research like ultimate axial load, ultimate deflection, load vs deflection comparison, Percentage of strength are studied.
