| 摘 要： | 对建筑结构进行弹性动力时程分析时,为了既能让设计人员易于操作,又能在地震波选取方面不失合理性,根据上海市某超限高层结构设计实例的弹性动力时程分析结果,探讨了具有实际工程意义的选波方法。研究表明,无论是基底剪力还是基底弯矩,地震波三向输入的结构响应均比单向输入的结构响应小。采用小样本容量的地震波输入时,人工波输入数量的增加对降低地震波的总体离散性有显著作用。

| Abstract: | In elastic time-history dynamic analysis for building structures,both easy to operate and rationality in waves selection are both important.By using to the results of elastic time-history dynamic analysis for structural design of a Shanghai superhigh building,the wave-selection with engineering significance is discussed.The study shows that for the bending moment or the shear force of base,structure responses of three-direction-input are smaller than the response of one-direction-input.When using small sample size of earthquake waves.The increase in the number of artificial waves can reduce the overall dispersion of earthquake waves. |
