A simplified design procedure for underground Reinforced Plastic Mortar (RPM) pipe is proposed. This procedure is based on finite-element analyses of the pipe-soil system and composite laminate analysis of the pipe. With the proposed method, the designer is able to select the best trench geometry and backfill conditions, to determine the construction effects, and to devise the constituent pipe materials according to the given installation conditions for a reliable and cost-effective design. Existing design methods of underground flexible pipes were evaluated. A thorough investigation of the problems encountered with the RPM pipe is made to study the possible modes and causes of failure. The new design method is based on a composite beam element model to account for the failure modes pertinent to fiberglass-reinforced plastic pipes. The design procedure and the required soil and pipe materials data are described. It is shown that simpler performance limits are needed and that the proposed design procedure can be fully implemented once these data are provided.
