Combined Footing: An Important Structural Design Element

By: Javier Encinas, PE | April 24, 2016 ASDIP FOUNDATION includes the design of concrete combined footings. This structural engineering software is based on the latest ACI 318 provisions. This post covers the steps in the design of combined footings when subjected to a combination of vertical loads, horizontal loads, and bending moments. 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 supporting this column together with an interior column on a [...]

Spread Footings Under Biaxial Bending: A Complex Design Subject

By: Javier Encinas, PE | February 7, 2016 ASDIP FOUNDATION includes the design of concrete spread footings. This structural engineering software is based on the latest ACI 318 provisions. This article covers the complexities inherent to the design of spread footings when subjected to a combination of vertical loads, horizontal loads, and biaxial bending. For a simple spread footing with a vertical compression load, the resulting bearing pressure is uniform and the shear and bending can be calculated easily by hand. If the column is at the corner of a building, then biaxial moments could be transferred to the footing. [...]
