Test and Study on Wind Loads and Responses of Glass Curtain Wall and Skylight Influenced by Group of Structures/Wang Zhihong¹，Jiang Yong²，Wang Zhaomin³(1 Hyder Consulting Limited,Shanghai 200020,China; 2 China Academy of Building Research,Beijing 100044,China; 3 Department of Civil Engineering, Tongji University,Shanghai 200092,China)

Abstract: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.

Keywords:wind tunnel test; wind pressure; wind introduced vibration; dynamic coefficient
