Analysis of Structurally Restrained Eccentrically Loaded Footings
One potential way to prevent overturning of an eccentrically loaded footing and increase its efficiency is to hold the heel of the footing down into the ground with a structural member such as a cable. This study involved the finite difference numerical modeling of square concrete reinforced footings, on a homogenous mass of soil, restrained at the tension side with steel cables. The numerical models concentrated on the elastic behavior of soil. From the output of the numerical model, the bearing stress underneath the footing and the tension force in the steel cable were analyzed. A similarity between the model stresses and the stresses in an elastic and cracked concrete beam was observed. In this study, a simplified method, using a transformed area of the cables and assuming a linear strain, was proposed and was compared with the numerical method in terms of the bearing stress and the cable force.
