Abstract
Currently, two methods are available for the design of reinforced concrete pipes: the indirect design method and the direct design method. However, changes to indirect design procedures and proper application of the direct design method may not be well understood by designers. The goal of this work is to present designers with a concise history and major concepts of both methods to facilitate the proper application of either method for reinforced concrete pipe. The development of the indirect design method is given with emphasis on changes in the bedding factor, which is a constant that relates the strength of pipe in the three-edge-bearing test to the strength of pipe in the installed condition. The development of the standard installations and direct design method are presented, and finally a comparison between design results from both methods is made. Recommendations for reinforced concrete pipe design and the proper application of the bedding factor are provided. The direct design method is promoted as a superior method for the design of reinforced concrete pipe.
