【摘要】 本文首先通过线性滤波器法模拟了佛山世纪莲体育场大跨度索膜结构的风速时程曲线,然后根据风洞试验提供的体型系数,利用通用有限元软件Strand7计算结构的响应。本文着重讨论了在不同风速及不同方向的风作用下整个张拉索膜结构的动力响应．最后通过对响应结果的统计分析,得出相应结论．更多还原

【Abstract】 Wind velocity time-history curve of long-span cable-membrane structure in Foshan Sport Century Lotus Stadium is simulated by auto-regressive method. Then the response of the structure is calculated by the finite element software Strand7 according to the wind load shape coefficients from wind tunnel test. In this paper, the dynamic response of the structure due to the different velocities and the symmetry-dissymmetry wind are discussed. Some conclusions are made through the statistical analysis of the response results.更多还原
