【摘要】 北京体育大学田径训练中心屋盖为大跨度空间钢管桁架结构。根据反应谱法和时程分析法对屋盖结构在水平和竖向地震作用下的地震反应进行了计算分析,采用谐波叠加法数值模拟屋盖结构的风速时程并计算了屋盖结构的风振响应,获得了屋盖结构的荷载风振系数,为风荷载的计算提供了理论依据。更多还原

【Abstract】 The Steel Roof of the Beijing Sport University Track and Field Training Center is a large-span spatial steel tube truss structure. Response spectrum method and dynamic response history analysis method are used to calculate the seismic response under the horizontal and the vertical earthquake function. This paper introduces the harmony superposition method to simulate the wind speed, and caculates the wind - induced dynamic response of the large - span steel roof in time domain, and then gets the result of wind - induced vibration coefficient. It provides the theoretical foundation to caculate the wind load.更多还原
