FEM Simulation of an Elliptical-Shaped Corrugated Steel Culvert Pipe for Highway Construction
In this paper, we discuss the design and calculation methods of elliptical-shaped corrugated steel culvert pipe (ECSCP) 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. The ECSCP in this paper is a kind of culvert which is fabricated to an elliptical shape with several pieces of corrugated steel plates which are jointed by high strength bolts. This study is conducted on the basis of the ECSCP used in the construction of Shanghai North Outer Ring Line Highway in China. 3D FEM analysis is performed considering several parameters such as modulus of elasticity of the surrounding backfill soil, length of major and minor axis of elliptical-shaped section, eccentricity of vehicles. Some design methods are proposed in this paper, and they will be useful guidelines for safe design of ECSCP.
