The purpose of this study is to find out the strength index of ground motion related to the maximum response of low and middle rize inelastic buildings. It is known that the maximum response of the buildings of short natural period is related to the peak ground acceleration and that of the building of the longer natural period is related to the peak ground velocity, but the maximum response values by the ground motions normalizede by these indexes show large randamness. The ground motion is assumed as the sequense of pulses and the maximum impulse defined as the time integral of the pulse is strongly related to the maximum response and is not related to the natural period.

本研究的目的是找出与中低里泽弹性建筑物最大反应有关的地震动强度指标。短自振周期建筑物的最大反应与地震动峰值加速度有关，长自振周期建筑物的最大反应与地震动峰值速度有关，但用这些指标归一化后的地震动最大反应值具有较大的随机性。假定地震动为脉冲序列，脉冲的时间积分定义为最大脉冲，它与最大反应密切相关，而与自振周期无关。
