| 摘 要： | 利用ansys有限元软件,对60m跨的凯威特、施威德勒、联方单层球面网壳进行弹塑性动力失稳研究。结果表明:阻尼和初始几何缺陷对凯威特和联方网壳影响较大,对施威德勒影响较小;水平地震对结构的影响远大于竖向地震;3种类型网壳中,施威德勒网壳的抗震性能最佳。据此,提出在网壳选择与设计时应降低结构初始几何缺陷,增设阻尼减震隔震构件。

| Abstract: | With the help of the finite element software ansys, this article studys the dynamic instability of the 60m span＇ s kiewitt, schwedler, lianfang single spherical shell. The results show that： The damping and initial geometric imperfections great influence on Kiewitt and lianfang reticulated shell, has little effect on Sehwedler; Influence on horizontal seismic is far greater than the vertical earth- quake ; Three types of reticulated shells, net shell the seismic performance of the best. On this basis, put forward in the selection and design should reduce net shell structure initial geometric imperfection, adding damping vibration isolation components. |
