LUEVANOS ROJAS, A.. A new model for the design of rectangular combined boundary footings with two restricted opposite sides. Rev. ALCONPAT [online]. 2016, vol.6, n.2, pp.173-189. ISSN 2007-6835.  https://doi.org/10.21041/ra.v6i2.137.

This document presents a new model for the design of rectangular combined boundary footings with two restricted opposite sides, taking into consideration the real pressure of the ground on the contact surface of the footing in order to obtain: the moments around the longitudinal axes parallel to axis “Y-Y”; the moments around the transversal axes parallel to the “X-X” axis; the unidirectional shear force (Flexural shearing); and the bi-directional shear force (penetration shearing) for the two columns. The real pressure of the ground is presented in terms of the mechanical elements that act on each column (P, Mx, and My). The mathematical approach suggested in this work gives results with a tangible preciseness in order to find the most economical solution.
