Abstract
This report presents the results of an investigation of the capacity of thermoplastic culvert pipe in hoop compression and the resistance of profile wall pipe sections to failure by local buckling. The work was carried out to support development of design provisions (for plastic pipes and culverts) to be included in the AASHTO load and resistance factor design (LRFD) specifications. At present, design methodology and properties for plastic pipes and culverts are governed through procedures developed for metal products. The use of plastic pipe is increasing and, therefore, so is the need for provisions to assist structural engineers to make safe, cost-effective use of these materials. (A)
