Design of Residential Foundations

The Design of Residential Foundations course is part of our Structural Course Category and provides guidance on design and construction of residential foundations. The course includes information on concrete (plain and reinforced), masonry (unreinforced and reinforced), and other type of foundation structures (insulated concrete forms and wood foundation walls).

A foundation supports and anchors the superstructure of a building and transfers all loads (including those from flood, wind, or seismic events) imposed on it directly to the ground. Foundations distribute the loads to the earth over an adequate area so that loads do not exceed the bearing capacity of the soil and so that lateral movement or settlement is minimized. In cold climates, the bottom of the foundation must be below the frost line to prevent freeze-thaw damage and frost heave of the footing.

A foundation in residential construction may consist of a footing, wall, slab, pier, pile, or a combination of these elements. This course addresses the following foundation types:

  • Crawl space
  • Basement
  • Slab-on-grade with stem wall
  • Monolithic slab
  • Piles
  • Piers
  • Alternative methods

This course is based on Chapter 4 of the U.S. Department of Housing and Urban Development document “Residential Structural Design Guide”, Second Edition.

This course is intended for use by civil  and structural engineers, design and construction professionals, students and others interested in learning about design of residential foundations.
