Design and analysis on steel structure roof of Guanggu Air Rail High-tech Avenue Station
In order to achieve the architectural modeling of the outer cantilever and the central raised skylight of the steel structure roof of Guanggu Air Rail High-tech Avenue Station.A cascade self-balancing structure system was proposed,namely the first level of the self-balancing structure of the suspen-dome and the second level of the self-balancing structure of the double-side cantilever beam-column frame,which realized the unified integration of the architectural and structural functional forms,and solved the problem of thin column compression and eliminated the impact on the foundation.The static and nonlinear stability analysis of the structure was carried out by using SAP2000,which supplemented the stress analysis of ABAQUS beam-column joints,based on the stress characteristics of the upper structure,a foundation form combining inner pile foundation and outer single foundation was adopted.The results show that the upper structure and foundation design is reasonable,the overall stability is good,and the beam-column joints are well stressed.
