摘要
管-管格构梁式支承体系是一种广泛采用的幕墙支承结构形式,在上海北外滩某商务楼中庭钢结构项目风洞试验数据的基础上,考虑塔楼"穿堂风"群体效应的影响,对工程方案进行静、动力分析,其研究方法和结论可推广到类似幕墙结构形式。
Steel tube lattice beam is used widely. The test conditions and main results of wind tunnel test for a project in Shanghai are introduced. The wind pressure distributions on this long-span glass curtain wall 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.
