Abstract:The main building of sports center in Tangye district of Jinan city is concrete structure, and the roof and curtain wall are steel structures. Some key points in designing the roof truss structure were analyzed, including lectotype of structure，load value and calculation method of the main steel members. Connecting point of steel tube with large diameter was designed and the related method of connection was also proposed. The bearing capacities of!roof structure under the actions of earthquake and wind loads were analyzed.

Keywords: truss structure; joint design; limit bearing capacity
