摘要：

为了研究台风作用下弦支网壳结构的动力失效,采用谐波合成法模拟杭州和舟山地区台风作用下弦支网壳表面各节点的风速时程,在ANSYS中建立弦支网壳结构有限元模型,分析结构自振特性,分别对时域内2个地区台风作用下弦支网壳结构的动力性能进行数值模拟,通过对各指标的分析,得出弦支网壳结构在风荷载作用下动力响应的特点.参考网壳结构在地震作用下动力失效的相关研究,结合弦支网壳动力响应特点,以节点最大位移、塑性杆件比例以及拉索松弛为指标,提出台风作用下弦支网壳结构动力失效判定准则.结果表明,该准则具有一定的合理性和适用性.
Abstract:

Thewind speed time history of nodes under typhoon of Hangzhou and Zhoushan were simulated by using harmonic wave superimposing method, in order to analyze the dynamical failure of suspendome under typhoon load. The finite element model of a suspendome was established by ANSYS|the free vibration characteristics were analyzed;dynamic properties of the suspendomes in the two cities were simulated in the time domain, and the characteristics of the dynamic response of suspendomes under wind load were obtained. Referring to the researches on dynamical failures of shell structures under earthquake and the dynamic behaviors of suspendomes, the criteria of dynamical failure of suspendomes under typhoon load were proposed by focusing on three indexes: the maximum node displacement, the ratio of plastic members and the slack of cables. Results prove the rationality and applicability of the criteria.
