（浙江中南建設集團有限公司，杭州 310052）[摘要] 以現行荷載規(guī)范風振概念為依據，提出單層索網結構應按柔性結構的風振系數分析；利用地面粗糙度參數，很容易得出單層索網振型系數；體型系數取陣風作用時的平均值，能夠真實地反映索網的實際工作狀態(tài)。根據單質點振動理論，分析主體結構對索網振型系數的放大作用。在選取拉索的斷面時，還應考慮溫度應力的影響。
[關鍵詞] 單層索網；風振增大系數；振型系數

( Zhejiang Zhongnan Construction Group Ltd., Hangzhou 310052, China)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
