This paper describes the evaluation of seismic capacity related to damage degree for repaired reinforced concrete members, based on experimental results of lateral cyclic loading tests with column specimens. The analytical seismic capacity evaluation of repaired reinforced concrete members was also investigated. The following conclusions have been obtained from this study. The ductility of repaired RC members was significantly affected by the buckling of the longitudinal reinforcing bars in the primary loading. The mechanical behaviors of repaired RC members can be analyzed by considering damage history and repairs. The initial stiffness of repaired RC members can be calculated using stiffness reduction ratios. The maximum strength of repaired RC members can be calculated by considering the strain hardening of the longitudinal reinforcing bars. |
