Abstract: Comprehensive hall of Pinghe Bilingual School Qingpu is composed of a swimming pool and a basketball hall.The lower two floors adopt steel frame structure, and the upper roof adopts a lattice column-space tube truss roof system.Researches on the key technologies such as the selection of the lateral force system and the section, connection modebetween lattice columns and substructures were researched. The SAP2000 structural analysis software was adopted to buildthe single model of roof and the integral model of the structure. The internal forces and deformations of the roof of twomodels under the horizontal and vertical loads were analyzed and compared. At the same time, based on the stresscharacteristics of this project, the overall stability of the roof and the stress of the key joints were variously analyzed. Theanalysis results show that the stress ratio of key parts is not greater than 0. 85, the stress ratio of other elements is notgreater than 0. 90, and the deflection of the roof under vertical load and displacement under wind load and earthquake meetthe requirements of specifications,the roof structure system is safe and feasible, the joint connection is reliable, and thecurrent design can fulfill the design goal.

Keywords:steel roof; tube truss; lattice column; pin support; envelope design; stability analysis; joint analysis;UHPChanging plate
