( China Architecture Design ＆Research Group( Shanghai), Shanghai 200120, China)Abstract: Combined with construction project of Yangzhong Olympic Stadium, a wind tunnel experiment was carried out as to a 26-meters-long cantilevered-roof. And wind load calculation and stochastic wind vibration response analysis were aclueved with the help of FEM analysis. Shape factor of wind load of the cantilevered-roof, basic wind pressure, and wind vibration faction were analyzed to provide reasonable and reliable wind load data for structure design.
Keywords: cantilevered roof; wind tunnel experiment; wind vibration factor
