By evaluating the shear strength using the seismic capacity index, the necessary shear strength from existing earthquake-resistant standard and the suitability of seismic evaluation were investigated. The results indicate the following: 1) All buildings before strengthening and buildings with Qu≧Qun after reinforcement seem to be a strength type building. Buildings with Qu<Qun seem to be a ductile type building. 2) For the buildings with Qu<Qun, the base-shear coefficient is higher than 0.4, and there is no significant difference with the base shear coefficient of buildings with Qu≧Qun. 3) Referring to the seismic strengthening plan, the seismic performance of buildings with Qu<Qun is estimated to be more than Ds=0.5 and for buildings with Qu≧Qun, it is estimated to be equivalent to less than Ds=0.5.
