摘要
从水工建筑物抗震设计规范的标准反应谱出发,利用反应谱与功率谱的近似关系,求出相应的功率谱来生成初始人工地震波,并利用蜂群算法对人工地震波产生的计算反应谱向标准加速度反应谱的逼近迭代进行优化,使优化后的误差更小。
By using the standard response spectrum specified in the current seismic design for hydraulic structures and the approximate relationship between accleartion response spectra and power spectra,the artifical earthquake ground motion can be generated initially,and ABC algorithm is used to optimize the generated response spectra＇s approximating the standard accleartion response spectra in each interation,which makes the approximating error more smaller.
