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.

Rapid evolution is taking place in the water market world wide - driven by increased consumer demand allied to the rarefraction of clean water. The inherent characteristics of composites materials associated with current materials and production technology is allowing the increased use of previously high cost materials and processes at ever decreasing costs. The Handbook is designed to bring specifiers up to speed with these materials and the new areas of application associated with them, exploring the scope, performance, cost effectiveness and environmental and legislative consequences of

Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in Trenchless Construction covers design and recommended installation procedures for precast concrete pipe for jacking in trenchless construction. This Standard addresses piping intended for the conveyance of sewage, industrial wastes, stormwater, and drainage, as well as for utilities and access ways. The design criteria include: structural aspects, such a s circumferential flexure, thrust, shear and radial tension strengths; crack width control; longitudinal thrust produced by jacking; and requirements for handling and installation. The structural design of concrete pipe is based on a limits state design procedure that accounts for strength and serviceability criteria and is consistent with the procedures in Section 17 of the AASHTO Standard Specifications for Highway Bridges.
