Design of strap footing
WebStrap or cantilever footings are designed on the basis of the following assumptions: 1 . The strap is infinitely stiff. It serves to transfer the column loads to the soil with equal and uniform soil pressure under both the footings. 2. The strap is a pure flexural member and does not take soil reaction. WebIn strap footing, the foundation under the columns is built individually and connected by a strap beam. Generally, when the edge of the footing cannot be extended beyond the property line, the exterior footing is …
