Discussion on the Design of Steel-concrete Composite Continuous Beam and Shear Connector for Rail Transit
Due to the fact that steel-concrete composite beam structures can fully utilize the performance advantages of concrete and steel structures,they have gradually been promoted in the design of rail transit bridges.At present,there are few references for the design and calculation of the upper structure of rail transit composite beams,and there are still differences in the calculation of shear members according to different design standards and specifications.Therefore,it is necessary to analyze and explore the above issues.Combining the design of a steel-concrete composite continuous beam(45+70+45)m in a domestic rail transit project,this article analyzes the stress characteristics of steel-concrete composite beams through finite element software modeling and calculation,and compares and discusses the shear bearing capacity calculation formulas for steel-concrete composite beam shear members in different domestic and foreign standards,in order to provide some reference for the design and calculation of bridges of the same type.
