Abstract:According to the architectural characteristics  of Hohhot East Passenger Station, the structural form of the composite arch was proposed to realize the perfect unification of architecture and structure. The static, dynamic and stability analyses of the structure were performed by SAP2000 software. The analysis results show that the dead load and thermal action control the structure properties; the effects of wind load and seismic action are minor; the folded plate (beam) structure between the arch elements has a great influence on the overall structure, and the connection between the longitudinal H-shaped steel beam, the folded plate (beam) structure and the concrete-filled steel tubular arch ring have great influence on the overall stiffness and stability of the structure. The method of implementing the node rigid connection was proposed. Finally, the sliding construction scheme of the arched roof, and the key problems and solutions for concrete pouring in the concrete-filled steel tubular arch were introduced.

Keywords:composite arch structure; stability analysis; node design; sliding construction
