大跨度屋盖结构风振响应的时程分析法
The Time-history Analysis Method of Wind-induced Dynamic Vibration of Long-span Roof Structure
【摘要】 文章对大跨度屋盖结构风振响应的一般方法进行了概述,结合某体育场主看台屋盖结构,运用时程分析方法对主看台屋盖结构节点位移响应进行了计算,并与运用频域方法计算的结果进行了对比和分析。
【Abstract】 This article summarizes the general measures of wind-induced dynamic response of long-span roof structure,in combination with the roof structure of spectator stand of a sports stadium,does calculation to its node displacement by time-history analysis and makes comparison with and analyzes the results of frequency-region methods.
