Study on Steel and Concrete Composite Structure Bridge

Abstract

With the development of the transportation industry, bridge construction has become particularly important. Bridge materials can be divided into many types, and different materials have different properties. In view of the existing problems of bridge construction materials, this paper mainly studies the structure of steel and concrete composite bridge. By understanding the advantages of steel and concrete composite bridges, the stress characteristics and durability of different types are analyzed. The analysis results show that the steel and concrete composite structure bridge is beneficial to improve the bearing capacity and performance of the bridge structure. In addition, measures such as coating, weathering steel, high performance concrete and prestressing can be taken to improve the durability of steel and concrete composite structure bridges. It is shown that the steel and concrete composite structure can play the respective characteristics of the two materials, so the structure can be widely used in the future bridge construction.
