This paper describes a method for post-earthquake damage evaluation for reinforced concrete buildings. A concept of residual seismic capacity ratio, which is the ratio of residual seismic capacity to the original capacity, was introduced in order to evaluate post-earthquake damage level of buildings. Loading tests of reinforced concrete columns were carried out in order to estimate the residual seismic capacity ratio. The residual seismic capacity ratios for both ductile and brittle columns were evaluated based on the residual energy dissipation capacity of the test results. Validity of the proposed method was examined by seismic response analyses of single-degree-of-freedom system. It was shown that the residual seismic capacity ratio gave conservative prediction of the intensity of seismic motion which damaged structure could stand against.
