Abstract: In 1970, the American Concrete Pipe Association (ACPA) began a long range research program which focused on the behavior of buried concrete pipe. The research resulted in the comprehensive finite element computer program SPIDA, Soil-Pipe Interaction Design and Analysis, for the direct design of buried concrete pipe. Since the early 1980's, SPIDA has been used for a variety of studies, including the development of four new Standard Installations, and a simplified microcomputer design program, SIDD, Standard Installations Direct Design. These four new installations are specified in the newly introduced ASCE Standard Practice for Direct Design and Buried Precast Concrete Pipe (SIDD). Through the use of the new installation types and design details provided in this ASCE standard some rational and cost-effective benefits can be realized by the designer through the ability to optimize the design of precast concrete pipe over a wide range of site specific and installation dependent characteristics.
