Abstract

Abstract

The reinforced concrete structure used in the prefabricated subway station is an important load-bearing component， and its mechanical properties determine the technical quality of the subway station. Conventional reinforced concrete structures have problems such as large amounts of concrete materials， complex construction techniques， and high self-weight， resulting in greater difficulty in transportation and assembly. This paper introduced the concept of composite structures into subway station structures， proposing a prefabricated steel-concrete hollow composite structure to optimize the design of reinforced concrete structures. To ensure that the material costs of conventional prefabricated reinforced concrete structures and the prefabricated hollow composite structures were similar， the cross-sectional reinforcement of prefabricated hollow composite structure was designed. A model for calculating the bearing capacity of prefabricated hollow composite structures was proposed， and the N-M relationship curve was drawn. The calculated results agreed well with the finite element simulation values.
