Design and research on roof structure of main building of Taiyuan Wusu International Airport Terminal 3
The steel roof of main building of Taiyuan Wusu International Airport Terminal 3 consists of high roof,low roof and VIP hall.It adopts the slope roof shape of ancient Chinese architecture,and the building height is 43m.The high roof and low roof are equipped with plane trusses and quadrangular mesh frames to meet the demands of force transmission.The vertical support structure can be fixed or hinged according to the column height and bearing capacity,and some columns are made of concrete-filled steel tube to improve the lateral stiffness.The key joint design pays special attention to the skylight structure and the Y-shaped column,Y-shaped column adopts cast steel at the fork and is connected at the top by a pin joint with articulated bearings.For the exposed steel structure,the appearance quality control method was discussed to ensure that the iconic elements such as Y-shaped columns meet the architectural requirements.
