This publication, Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD), (ASCE 15-93), is applicable to buried concrete precast pipe intended for the conveyance of sewage, industrial waste, storm water, and drainage. The standard practice covers the direct design method, manufacturing specification, and standard installations. It is based on research and testing over the past twenty years to develop a more rational design procedure for the direct design of buried concrete pipe based on engineering principles followed for the direct design of other reinforced concrete members. The direct design method is an improvement on the indirect design method based on the three-edge bearing test which does not represent the soil pressure distribution around an installed pipe. The soil pressure distribution on a buried pipe depends on soil-pipe interaction, which, in turn depends on the soil material and installation procedure. The direct design method provides the procedure for determining the pressure distribution coefficients for the standard installations. Four types of standard embankment installations and four types of standard trench installations are covered in the standard. The limits state design procedure specified for the design of pipe is consistent with the procedures outlined in Section 17 of the AASHTO Standard Specifications for Highway Bridges. The commentary provides supporting background data.
