In order to explore the design method of corrugated steel plate(CSP)-concrete composite box structure,based on an engineering example,the concept,application technology,and design steps of Concrete-Steel Composite Beams were systematically discussed.Firstly,based on stiffness equivalence,the Concrete-Steel Composite Beams was equivalent to a steel Plate arch.Then,a finite element analysis model was established to solve the internal forces of the structure,and the reliability of the structure was judged by the calculation method specified in the specifications.The design process of the foundation can refer to relevant highway bridge design specifications and code.The first application of this structure provides a new structural method for bridge engineering,and can provide reference for similar projects.
