Steel bars made of corrugated steel have stronger bearing capacity than ordinary steel bars, and generally speaking, corrugated steel will be mixed with concrete when combining, which can enhance its bearing capacity and stability.Because corrugated steel has such excellent performance and bearing capacity, it has been widely used and concerned by architects in the construction of bridges.In this study, we introduce and describe the structure of corrugated steel and its composite bridge in detail.At present, the bridge design code does not give a detailed description of the special structure of the design materials.
