•A railway station canopy numerical wind tunnel simulation of wind and rain

Station canopy wind and rain, about 520 meters, 114 meters wide, by hanging in the steel truss roof beam curved-shaped composition, Figure 1.1 for the internal real, unique for this type of large-span roof structure, its size and wind-induced vibration coefficient of wind load parameters such as the existing building did not provide load norms. In order to ensure wind and rain canopy roof design wind resistance safety, using ADINA software to the structure of the numerical simulation of wind tunnel tests, which have been required in the engineering design of wind-induced vibration coefficient and shape factor.

　　　　　　　　• Roof numerical wind tunnel simulation

Roof structure size of about 193 meters, 125 meters wide. The new building design, roof curves are more complex, surrounded by cantilevered, architectural effects are shown in Figure 2.1.
