According to these records, some maximum acceleration on ground surface can be over 980 (cm/sec2) (= g : gravity acceleration) near epicenters, but these maximum values are not always corresponded to the damages of building structures. The acceleration records have their own properties in period or running time of big acceleration and the structure damages are considered to depend on these properties. That is because the dynamic response analysis about the structures is needed based on structural period. Many countries use the base shear coefficient in seismic design codes. These values are usually 0.2 g , 0.1 g and others for static analysis. These values are very smaller than the acceleration records and that makes difficult the inelastic dynamic response analysis. This is because the inelastic dynamic response analysis is usually applied to the high-rise buildings considered to have the property of long structural period. Therefore, this paper describes the results of inelastic dynamic response analyses using Bi-linear model of Single Degree of Freedom. The acceleration records used in analyses are ones recorded in Japan, U.S.A. and others. In Bi-linear model, the yielding strengths per mass are 0.2 g or 0.1 g , the damping ration is 5%, and the degrading ratio of the stiffness is 1/1000. According to the inelastic analyses, the response acceleration, velocity and displacement spectra are calculated in short structural period of 1.0 (sec) and less, too. In conclusion, the response displacement is corresponded to the seriousness in the building damages well, regardless of the peak acceleration. The response absolute acceleration and the response velocity are not always corresponded to the seriousness in the building damages.
