Abstract:This study investigated asymmetric deformation (racking) of installed thermoplastic pipe. Ohio Department of Transportation (ODOT) construction records were reviewed to determine the extent of racking noted within Item 611 Conduit Evaluations. Next, a rational method for assessing racking was developed within the framework of the AASHTO LRFD Bridge Design Specifications, Section 12. A spreadsheet was developed to aid in the assessment procedure. The results of the methodology were compared to test cases analyzed using the 2D culvert specific finite element software CANDE. Finally, a one-day course covering the basics of the finite element method was developed and presented to ODOT staff.
