Abstract: In order to investigate their seismic behaviors, one contrasting reinforced concrete short column and three reinforced concrete short columns strengthened with concrete and exterior steel plate were tested subjected to low periodic reverse load. The parameters of test specimens included thick of exterior steel plate and ratio of compress load. The composite strengthening with concrete and exterior steel plate can improve shear bearing capacity of reinforced concrete short column remarkably.
