High-frequency-pressure-integration tests were carried out in a wind tunnel to investigate wind load characteristics on smooth cantilevered roof and wavy-shaped cantilevered roof,both of which have the same size. The effects of wavy-shaped roof surface have been evaluated in wind tunnel test. Wind pressure distribution shows that,wavy shape does not change the main mechanism of wind load,but intensifies the separation on the front edge of the roof. Bending moment coefficient is a controlling factor for the ...
