NHI Course 132037 – Spread Footings: LRFD Design and Construction

This updated course (January 2012) replaces NHI training 132037 Shallow Foundations, which was developed in 2001. Designed in accordance with the AASHTO Bridge LRFD Specification, 5th Ed., 2010, the course describes basic principles and state-of-the-practice analysis, load and resistance factor design (LRFD) procedures, and construction procedures for shallow foundations in soil and rock with particular application to transportation facilities.

The main topics covered are LRFD procedures for spread footings, vertical stress distribution, tolerable settlement criteria, settlement criteria in coarse-grained soils, settlement in fine-grained soils, time rate of consolidation settlement in fine-grained soils, bearing resistance in soil and rock, sliding resistance in soil and rock, problematic soils and ground improvement techniques, and inspection and construction monitoring methods for spread footings. Group exercises are interspersed throughout the course, enabling participants to be actively involved in the learning experience. This course provides FHWA recommended technical guidance in accordance with standard of practice for design and construction of spread footings for LRFD.
