Chapter 5 Footing Design - Engineering

1 Chapter 5 Footing Design By S. Ali Mirza1 and William Brant2 Introduction Reinforced concrete foundations, or footings, transmit loads from a structure to the supporting soil. Footings are designed based on the nature of the loading, the properties of the Footing and the properties of the soil. Design of a Footing typically consists of the following steps: 1. Determine the requirements for the Footing , including the loading and the nature of the supported structure. 2. Select options for the Footing and determine the necessary soils parameters.

9. Shear Lug Design Normally, friction and the shear capacity of the anchors used in a foundation adequately resist column base shear forces. In some cases, however, the engineer may find the shear force too great and may be required to transfer the excess shear force to the foundation by another means.
