Abstract:The Cultural and Sports Archives Center of Lixia District in Jinan City is a comprehensive building that integrates the functions of theater, swimming pool, basketball hall, archives, library, and science and technology museum. There are some design difficulties in this project, such as complex construction process, complex stress of steel truss, super long and discontinuous floor. Through the reasonable setting of prestressed concrete beam, steel truss, column on beam  and hanging column, the realization of multi-storey building function above large span space is ensured. Through detailed elastic-plastic analysis, the seismic performance of the structure is guaranteed to achieve. Through reasonable organization of construction sequence and fine analysis of truss joints, the safety and reliability of large-span area are ensured. Through the stress analysis of the floor and appropriate strengthening measures, the problem of over length and discontinuity of the floor is effectively solved.

Keywords:Cultural and Sports Archives Center of Lixia District; transfer truss; construction sequence; open-web truss effect；  joint analysis; comfort analysis
