摘 要: 大跨索网结构广泛应用于工程实际,该结构的风振系数是结构抗风设计的重要参数.以双曲抛物面椭圆平面索网结构为研究对象,通过三维有限元风振响应时程分析,得到了索网结构在不同矢跨比、阻尼比下的风振响应特点和风振系数的变化规律,由此给出一些有意义的结果和结论. The long-span cable nets structures are being widely used in practical engineering,and the wind-induced coefficient is important for the design of the structures.With the 3-D FEM,the wind vibration response of the oval-plane cable net structure is analyzed in this paper.The characteristics of the wind vibration response and the change regularities of the wind-induced coefficients for different rise-to-span ratios and damp ratios are obtained.Some useful results and conclusions are also given.
