| 摘 要： | 高层建筑用时程分析法分析地震动时,采用不同的地震记录,得到的内力、位移等结果差别很大,与底部剪力法或振型分解反应谱法的结果也有很大出入.地震波的选择又是时程分析法的重要环节,直接影响计算结果的正确与否和结构的安全.由于满足《建筑抗震设计规范》GB 50011-2001(2008)要求的地震波不止一种组合,对于这种情况,提出一种方法来进行最佳组合地震波的选择.

| Abstract: | With regard to adopting time-history method analyzes high buildings,the results of internal force and displacement vary largely from one earthquake wave to another one,and the results of them and of equivalent base shear method or response spectrum modal analysis are also different.The choose of earthquake wave is a key step in time-history method,which directly decides whether the results are accuracy and structure is safe.Because there is more than one earthquake wave combination which meet the requirements of code for seismic design of buildings GB 50011-2001（2008）,a method to selecting the optimal combination of earthquake wave ispro posesed. |
