Abstract:The station building of Qingdao Hongdao Railway Station of Jinan-Qingdao High-speed Railway adopts a steel-reinforced concrete hybrid frame structure combined with bridge-station combined structure. The square layer, rail-bearing layer and the elevated two main bridges are separated by joints, and the elevated waiting layer is designed without joints. In order to ensure the use of the steel roof on the elevated waiting layer, there are no joints in the whole. The middle part adopts a inverted triangle space tube truss. Wave-shaped structures at the north and south entrance adopt a spatial grid structure, and they are connected as a whole by a rectangular transition truss. In the structural design, the single working condition analysis of temperature effect, supplementary calculation of multi-point input seismic response time-history analysis, overall stability analysis of steel roof, extreme load stress analysis of steel roof, steel roof construction simulation analysis, finite element analysis of typical joints, dynamic elastoplastic analysis of the structure under rare earthquakes, progressive collapse prevention analysis, etc. were carried out. The analysis results show that the steel roof structure is safe and reasonable in design and has good seismic performance.
