Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations (SIDD)

Abstract

• Standard Practice for Direct Design of Buried Precast Concrete Pipe Using Standard Installations focuses on the direct design of buried precast concrete pipe using Standard Installations (SIDD). This standard, a revision of ANSI/ASCE 14-93, reviews the design and construction of the soil-pipe interaction system used for the conveyance of sewage, industrial wastes, stormwater, and drainage. In this standard, the SIDD method is used to account for the interaction between pipe and soil envelope in the determination of loads, pressure distributions, moment, thrust, and shear. Excavation, safety, foundation, bedding, sheathing removal, and trench shield advancement are among the construction requirements presented here. Four types of standard embankment installations and four types of standard trench installations are covered.

  This standard may be used as a reference in preparing project specifications based on the SIDD method, and the limits state design procedure is consistent with the procedures outlined in the AASHTO Standard Specifications for Highway Bridges. A commentary provides supporting background data.
