Un nuevo modelo para diseño de zapatas combinadas rectangulares de lindero con dos lados opuestos restringidos

This paper presents a new model for design of boundary rectangular combined footings with two opposite sides constrained taking into account the real soil pressure acting on the contact surface of the footing to obtain: Moments around of parallel longitudinal axes to axis “Y-Y”; Moments around of parallel transverse axes to axis “X-X”; Unidirectional shear force (bending shear); Bidirectional shear force (punching shear) to the two columns. The real soil pressure is presented in terms of the mechanical elements acting on each column (P, Mx, y My). The mathematical approach suggested in this paper produces results that have a tangible accuracy for find the solution more economical.
