| 摘 要： | 根据随机过程理论,考虑风压脉动及风的空间相关性,给出了具有空间相关性风场的计算机模拟方法,建立了一种适合大跨空间结构非线性风振响应计算分析的时域方法,并编制了相应的抗风设计程序.对一K8型索承网壳结构进行了非线性风振反应分析,分析表明该结构具有良好的抗风性能.通过改变几何、结构、荷载等参数,研究诸多因素对素承网壳风振反应的影响,结果表明矢跨比和撑杆长度是索承网壳抗风设计的主要控制参数.

| Abstract: | According to the theory of random process,the wind histories generation method which can consider the time and spatial correlativity of wind is given.The nonlinear wind vibration response analysis method in the time domain is established with the relevant program complied,which is adaptable to the long span structures.The results of a K8 type cable-supported lattice shell indicate the structure has good wind-resistance performance.In addition,through changing factors such as structural parameters,geometric ... |
