摘要

结合惠州会议展览中心风洞试验结果

对波浪形组合网壳结构的风荷载和风振响应进行了分析

包括:24个风向角下屋盖荷载分布特性分析;结构整体和局部的自振特性分析;根据风洞试验结果对6个风向角（0°、30°、45°、90°、135°和180°）进行结构的风致动力响应分析。根据风振响应分析结果

基于响应的不同振动特点

提出将屋盖结构分为独立屋盖结构、屋盖结构两端挑棚结构和整体屋盖结构3个部分

指出对这3部分最不利的风向角分别为0°、30°、90°。最后综合考虑各个风向角下结构的响应及风振系数

给出了最终的风振系数建议值。

Abstract

Using wind tunnel test of Huizhou exhibition center as an example

wind pressure and wind induced vibration of the compounding lattice shell are analyzed.The following contents are included: wind load distribution characteristics are given;the vibration characteristics are analyzed;the wind-induced dynamic response of the roof in six degrees is analyzed.According to the analysis results of the response of the roof and vibration characteristics

the roof are divided into three parts

they are separated roof

the cantilevered roof and the main roof.The dangerous wind angle for the three parts are 0 degree

30 degree and 90 degree

separately.With the consideration of the wind-induced response and the gust response factor in all direction

the final suggested gust response factors for wind-resist design in different parts are given.
