Experimental Study on Cast-Steel Joints of Hongqiao High-Speed Railway Station

Some cast-steel joints were used in the design of the Hongqiao high-speed railway station.In order to analyze the behavior and the bearing capacity of the cast-steel joints,the refine finite elemental analysis was conducted.Software SolidWorks was selected to calculate the finite elemental models.Then the stress distribution of the cast-steel joints were known,which indicates that the cast-steel joints have comparatively high load bearing ability and are safe enough.The full-scale experiments with well-designed reaction frames were done in the laboratory,which verify the reliability of the results of the refine finite elemental analysis.The optimization designs of the cast-steel joints were also done,and the proposals to reduce the total weight of the cast-steel joints were put forward.
