Study on Circular-Shaped Corrugated Steel Culvert Pipe for Highway Construction

s. In this paper, we discuss the design and calculation methods of Circular-shaped Corrugated Steel Culvert Pipe (CCSCP) used in highway construction. With many advantages such as lightweight, environment friendly, cost-effective, rapid construction, etc., Corrugated Steel Culvert Pipe (CSCP) have been widely used in highway construction acting as the alternative of RC culvert in China in recent years. It will not crack under impact loads or vibrations due to the inherent strength of steel and the flexibility of the corrugated pipe section. The high ring compression of the pipe absorbs and transfers the load to the surrounding soil around the entire circumference. In this paper CCSCP is a kind of culvert which is fabricated to a circular shape by several pieces of corrugated steel plates jointed by high strength bolts. In this paper, a serial test is conducted on site in process of the fabricating of the CCSCP used in the construction of Shanghai North Outer Ring Line Highway in China. In addition, 3D FEM analysis is performed with the intent of contrasting with the result of the test. Some design methods are proposed in this paper, and they will be useful guidelines for safe design of CCSCP.
