网壳结构抗震设计方法探讨

DISCUSSING UPON ANTI-SEISMIC DESIGN OF SPACE FRAMES

网壳等大跨空间结构动力性能与传统多、高层结构相比更为复杂且有明显不同,目前各国均缺乏相应的抗震设计规范。因此,对于网壳结构的抗震性能进行系统研究,提出合理、有效的抗震设计方法是十分必要的。本文依据基于性能抗震设计思想,归纳近年来网壳结构抗震性能的大量研究成果,提出新的网壳结构抗震设计方法,为我国网壳结构抗震规范的制定提出依据。

There are many differences between the anti-seismic behaviors of space frames and those of traditional buildings. In fact, there is still a lack of anti-seismic code for space frames until now. So how to perform the effective anti-seismic design of such structures has been the critical question in practice. According to performance-based anti-seismic design idea and significant research achievement obtained recently, the paper presents a new method for anti-seismic design of space frames that can provide reference for enacting new code in future.
