作者曾利用反应谱法对水中多柱结构进行了抗震分析。该方法基本上属于确定性分析方法。虽然它也部分地考虑了地震作用随机性质,但是由于所依据的地震记录太少,而实际地震的离散性又较大,所以求出的平均反应谱值不能正确反映随机地震的概率持征。另外,反应谱法也不能从理论上探讨地面运动与结构反应的内在规律(例如结构破坏与地震持续时
The author has used response spectrum method to analyze the multi-column structure in water. This method basically belongs to the deterministic analysis method. Although it also partially considers the stochastic nature of seismicity, the average response spectrum obtained can not correctly reflect the probability of random earthquake because of the small number of seismic records and the large discreteness of actual earthquakes. In addition, the response spectrum method can not theoretically study the inherent laws of ground motion and structural response (for example, structural failure and earthquake persistence
