电报网支持了在点点的最先进的技术支持了的玻璃窗帘人玻璃窗帘墙,广泛地在中国被使用。因为它在风负担下面的大偏转和高非线性,电缆线网络的动态性能是极大地与常规线性结构的不同。连续的膜理论被用来构造非线性的颤动电报网的微分方程,和泛音平衡方法被用来解决非线性的频率的分析公式。为了验证上述分析公式,公式的结果和非线性的女性的时间历史方法的精确性,被比较并且发现了在好同意。而且,微分方程和非线性的频率在这篇论文获得了的非线性的颤动是在波动的风负担下面的一张电报网的 wind-inducedresponse 分析的基础。
The cable net supported glass curtain wallas the most advanced technique in dot point supported glass curtain wall, is widely used in China. Because of its large deflection and high nonlinearity under wind load, the dynamic performance of the cable net is greatly different from that of the conventional linear structures. The continuous membrane theory is used to construct the nonlinear vibration differential equation of the cable net, and the harmonic balance method is used to solve the analytic formula of the nonlinear frequency. In order to verify the accuracy of the above analytic formula, the results of the formula and the nonlinear FEM time-history method are compared and found to be in good agreement. Furthermore, the nonlinear vibration differential equation and the nonlinear frequency obtained in this paper are the basis for the wind-induced response analysis of a cable net under fluctuating wind load.
