摘要
利用文献提供的最不利地震动,对网壳结构等大跨空间结构进行了分析,分别考察了仅水平输入和三向地震波输入的两种情况,对最不利地震动在网壳结构抗震设计中的适用性进行了探讨,并在一实际工程设计中进行了应用。大跨度空间结构在水平地震动输入时,宜按照的最不利地震动进行设计;在三向地震动同时输入时,应同时分别按所推荐最不利设计地震动和按常规选用的地震动,对大跨度空间结构进行抗震分析。
According to the severest ground motion data provided in other papers, reticulated shells and other kinds of large-span spatial structures are analyzed in two cases of only horizontal direction seismic input and three directions seismic input. The adaptability of severest ground motion applied in reticular shells anti-seismic design has been discussed, and the severest ground motion data has been apllied for design of a practical spatial structure. The severest ground motion should be applied in seismic design for reticular shells when just the horizontal direction seismic input is considered. Besides, the severest ground motion and the conventional ground motion must be applied in seismic design together when three directions seismic motion is considered simultaneously.
