摘要:
为了研究大跨度刚性空间结构在地震作用下的静力弹塑性,基于Push-over方法提出了一种适用于大跨度刚性空间结构地震反应分析的静力弹塑性分析方法,即Push-down方法; 建立了相应的结构弹塑性能力谱和地震非弹性需求谱,并提出了2种竖向加载模式,即1阶模态加载模式和多阶模态共同作用的加载模式; 通过2个数值算例,验证了Push-down法的有效性和精确度,同时给出了该方法的适用范围。
Abstract:
To study static elasto-plastic analysis methods about the seismic responses of long-span spatial structures, according to the Push-over method, a new static elasto-plastic analysis method named Push-down method, which was suitable for the long-span spatial structures, was proposed. Then the elasto-plastic capacity spectrum of the spatial structures and the seismic demand spectrum were established. Two kinds of vertical load patterns were proposed, that were the fundamental mode pattern of vertical loads and the multi-mode pattern of vertical loads. Two simple numerical examples were presented for verifying the validity and the accuracy of the method. The applicability scope of the Push-down method in long-span rigid spatial structure was suggested.
