摘　　要：选取佛山世纪莲体育中心的大跨度车辐式张拉索膜结构作为研究的原始模型,着重讨论不同预应力度和不同的膜的张拉刚度对结构自振特性和静风反应的影响。计算表明,结构的预应力度对结构的自振特性和静风反应影响较大。The rung-shape long-span tensile cable-membrane structure in Foshan Century Lotus Stadium was analyzed.The effects of different degree of prestressing and membrane tensile rigidity were discussed on natural vibration and static wind load response.Results show that the degree of prestressing has remarkable effects on structure′s natural vibration and response under static wind load of structure.
