ASCE 15-17 PDF Download

The ASCE 15-17 standard emphasizes the direct design method for buried precast concrete pipes. This method considers the soil pressure distribution around the installed pipe and provides a procedure for determining pressure distribution coefficients for standard installations. The standard reviews the design and construction of the soil-pipe interaction system used for conveying sewage, industrial wastes, stormwater, and drainage.

The SIDD method takes into account the interaction between the pipe and soil envelope to determine loads, pressure distributions, moment, thrust, and shear. It covers various aspects of construction requirements, including excavation, safety, foundations, bedding, sheathing removal, and trench shield advancement. The standard specifically addresses four types of standard embankment installations and four types of standard trench installations.

Updates in the ASCE 15-17 standard include correlating with the latest ASTM International and American Concrete Pipe Association (ACPA) documents for trench and embankment conditions, as well as current soil classifications. Additionally, design equations for nonreinforced concrete pipe have been added.

This standard can serve as a reference for preparing project specifications based on the SIDD method. The limit state design procedure outlined in the standard aligns with the procedures in the AASHTO Standard Specifications for Highway Bridges. The ASCE 15-17 standard is beneficial to civil engineering design professionals, consultants, owners, and transportation officials.
