Combined Footing Real-Life Example Using ASDIP FOUNDATION

By: Javier Encinas, PE | November 13, 2018 ASDIP FOUNDATION is a structural engineering software for the design of concrete footings. It includes the design of combined footings, based on the ACI 318 provisions. This document is a step-by-step design example of a real-life combined footing using ASDIP FOUNDATION. As an example, consider the combined footing shown below, which is part of the foundation of a pipe rack in an industrial plant. A typical bent consists of two steel columns closely spaced that share the same footing. The pipe rack is exposed to dead, live, and wind loads, whose reactions [...]

Combined Footings: How to Calculate the Bearing Pressures

By: Javier Encinas, PE | June 27, 2017 ASDIP FOUNDATION includes the design of concrete combined 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 combined footing. A combined footing usually supports two columns. The use of a combined footing may be justifiable under conditions where the distance between columns is short, so a large excavation is not required. There are two common scenarios in practice: A property line exists at or near the edge of an exterior column, so a normal isolated footing [...]
