联方—凯威特弦支穹顶结构的地震时程分析

Seismic time-history analysis of Lianfang-Kaiweite suspendome structure

采用时程分析法对联方—凯威特弦支穹顶结构进行了地震响应分析,研究发现,弦支穹顶结构在三向地震作用下,径向杆在下部支撑体系处影响最大,而环向杆相反,同时上部单层网壳杆件轴力影响较小,索的内力降低。

The paper carries out seismic response analysis of Lianfang-Kaiweite suspendome structure by applying time-history analysis method, The research finds out that： the impact of bottom radius rod bearing system will be larger under the triangle seismic of suspendome structure, while the ring rod instead, while the impact of upper single-layer rod is smaller, and internal cable force will reduce.
