Wind tunnel tests for the rigid model of Phoenix Media Center

Wind pressure distribution characteristics of the Phoenix Media Center flexible roof,in non-large deformation,were analyzed by wind tunnel tests of the rigid model.Meanwhile,the average wind pressure coefficients on the surfaces of the outer shell and the atrium with a suspended cable-membrane structure in different wind direction angles were obtained.It is shown that the wind effects of the majority of the outer shell are suction,except that positive wind pressure distributes on the main windward side of the outer shell and a small portion of the windward side of the insider shell,but the effects of wind pressure on the atrium with a suspended cable-membrane structure are mainly suction.
