Corrugated High-Density Polyethylene Pipe: Laboratory Testing and Two-Dimensional Analysis to Develop Limit States Design

Baseline data on buried thermoplastic pipe behavior under biaxial loading have been developed in a controlled laboratory environment. Deflections and local wall strains of a lined corrugated high-density polyethylene pipe were determined. Use of the finite element method and simplified design equations was then evaluated relative to the laboratory measurements. Measurements of soil response during the tests were used to evaluate the constitutive...
