摘要
运用网壳结构频域分析法,选取六类参数在其常用变化范围内,对单层双曲抛物面网壳进行风致振动节点位移响应分析,通过数值统计分析得到了六类参数变化对风致振动节点位移响应和风振系数的影响规律,结果表明:阻尼、地貌类型、支座高度参数是节点位移风振响应和风振系数的主要影响因素。
The wind-induced viberation response of saddle-shaped reticulated shell are analyzed in frequency domain method during usual vatialable range of six kind of basic parameters in this paper. And the influence of all kind of parameters on wind-induced viberation coefficient of response is discussed. Then by statistically analyzing results, damping, landform type, beating height parameter are the key impact factors.
