Abstract
Taking a long-span retractable roof structure, which locates in a coastal city of China, as an example, a wind tunnel test on a rigid model was carried out. This paper analyzes the wind load characteristics of this structure under three conditions: open, closed and closed with damage in small area of windows. The block shape coefficients as well as its variation with wind direction are given; meanwhile, this paper analyzes the fluctuation characteristics of wind load, obtaining the gust coefficient as well as the variation of fluctuation coefficients with wind direction, which can be applied to the design of coating members in this structure. By comparing the analysis results under three conditions, the following conclusion can be reached: the long-span structure is more resistant against mean wind load when the roof is open than when it is closed. There is no decrease in fluctuating wind load and in some wind directions; the fluctuating wind load will be even larger. Additionally, the damage in small area of windows does not much affect the wind load characteristics on structure.
