Strap Footing Design Example Using ASDIP FOUNDATION

By: Javier Encinas, PE | June 11, 2019ASDIP FOUNDATION is a structural engineering software for the design of concrete footings. It includes the design of strap footings, based on the ACI 318 provisions. This document is a step-by-step design example of a real-life strap footing using ASDIP FOUNDATION.Strap footing design exampleAs an example, consider the strap footing shown below, which is part of a steel retail building, with columns spaced in a 20 ft x 20 ft grid. One exterior column is located very close to the property limit. As a result, the column will be eccentric on the footing. [...]

Strap Footing: How to Calculate the Bearing Pressures

By: Javier Encinas, PE | April 16, 2017 ASDIP FOUNDATION includes the design of concrete strap footings. This structural engineering software is based on the latest ACI 318 provisions. This post explains the calculation of the soil bearing pressures in a typical strap footing. A strap footing usually supports two columns, so it's a special type of combined footing. If a property line exists at or near the edge of an exterior column, a normal isolated footing would be placed eccentrically under this column and it would tend to tilt. This problem may be prevented by connecting this footing [...]
