摘要(Abstract):

介绍了上海世茂北外滩商务楼中庭钢结构大跨点支玻璃幕墙及采光顶的风洞试验概况和结果,给出了玻璃幕墙的玻璃及支承体系抗风设计的风压确定方法,研究了幕墙及采光顶在考虑塔楼群体结构效应情况下的风压分布特征。利用风洞试验每个测点的风压时程信号,采用Newmark积分方法计算了幕墙及采光顶的风振时程响应,并以此为基础计算了风振系数。
The test conditions and main results of wind tunnel test for Shimao project in Shanghai are introduced.The methods to design the glass and supported systems on wind loads are given,and the wind pressure distributions on this long-span glass curtain wall and skylight are clearly showed.With the wind pressure signals of the test,the dynamic responses are computed by the Newmark integral method,and the dynamic coefficient is calculated with the statistical results.
