The results of an investigation into the local buckling capacity of profile wall thermoplastic pipe are presented. The investigation included a review of literature related to local buckling of thin sections, testing of currently available pipe, and development of a design model to predict the capacity of pipe in compression as governed by local buckling. A review of past work on the design of thermoplastic culvert pipe revealed little in the way of design methods for local buckling. The bulk of the research on buckling of thin sections has been completed by the light-gauge steel industry. A preliminary stub compression test was developed to evaluate local buckling and general capacity in compression. The results of the test correlate well with the buckling equations proposed by Winter for thin metal sections. These methods are based on the effective-width concept, which takes advantage of the capacity of a section after buckling. Design equations based on current AASHTO 50-year strength and stiffness properties have been proposed to and adopted by AASHTO. The design equations evaluate the capacity of thin sections in compression and in combined bending and compression. The check on combined bending and compression produces a limiting deflection for the field. The impact of the design method varies with the characteristics of the individual profiles produced by different manufacturers.
