摘要

以单层柱面网壳结构为研究对象,利用El-centro地震波对该类结构进行了时程地震反应分析,考察了结构的地震响应和抗震性能,研究了其在地震作用下的动力失稳特点。选取了几种几何尺寸不同的单层柱面网壳,分析了矢跨比和长跨比对单层柱面网壳动力稳定性能的影响。
The dynamic stability of single-layer cylindrical reticulated shells is discussed. By making use of El-centro earthquake wave, the time-history responses of the above structure to earthquake are obtained respectively. A detailed analysis on the dynamic stability and anti-earthquake of the structure is carried out. With considering various geometric sizes of single-layer cylindrical reticulated shells, the effects of rise-to-span and length-to-span to the structural dynamic stability are also analyzed.
