[摘要] 以现行荷载规范风振概念为依据，提出单层索网结构应按柔性结构的风振系数分析；利用地面粗糙度参数，很容易得出单层索网振型系数；体型系数取阵风作用时的平均值，能够真实地反映索网的实际工作状态。根据单质点振动理论，分析主体结构对索网振型系数的放大作用。在选取拉索的断面时，还应考虑温度应力的影响。

Abstract: According to wind vibration concept ofload code, it is put forward that single cable-network structure should be analyzed with wind vibration coefficient of flexible structure. Using the efuth roughness parameter, vibration coefficient of single cable-network was obtained easily. Wind pressure coefficient, using average value when gusty wind applied, can reflet the state of actual situation for cable-network really.  Based on the single mass vibration theory, enlargement role of main structure to vibration coefficient of cable-network structure was analyzed. When selecting the cable section, additional effect of temperature stess should be considered.
Keywords: single cable-network; enlargement coefficient of wind vibration; vibration coefficient
