摘要
线性加速度法分析了美国LomaPrieta地震中的SantaCruz地震波记录,得到了其三个方向(东西、南北、垂直)上的加速度反应谱,并作了位移、速度和加速度反应谱在各种阻尼条件下的对比。通过分析,SantaCruz波反应谱中的结构最不利周期为0.25s,而阻尼的增加可降低地震响应。
According to numerical analysis of Santa Cruz Wave which was recorded in the Loma Prieta Earthquake 1989 in American,the response spectrum of acceleration in three directions (East West,North South,Vertical and the comparison of the response spectrum of distance,velocity,acceleration with different damping conditions have been obtained by means of linear acceleration algorithm in this paper.From the analytical results,the most unfavorable natural period in the acceleration response spectrum of Santa Cruz Wave is 0.25s,and the increase of damping can decreases the response of earthquake.
