This paper presents a comparative study for the design of reinforced concrete isolated footings that are rectangular or circular in shape and subjected to axial load and moments in two directions using new models to obtain the most economical footing. The new models take into account the real soil pressure acting on contact surface of the footing and this pressure is different in all the contact area, with a linear variation, this pressure is presented in terms of the axial load, the larger moment around the “X” axis and the smaller moment around the “Y” axis, where the centroidal axes are “X” and “Y” of the footing. The main part of this research is to show the differences between the two models. Results show that the circular footings are more economical compared to the rectangular footings. Therefore, the new model for the design of circular isolated footings should be used, and complies with real conditions.
