This paper presents the complete design for RCFs (rectangular combined footings), assuming that the contact area with the soil is partially compressed. The formulation is carried out by integration to determine the moments, flexural shearing and punching shearing for all possible cases for footings under biaxial and uniaxial flexion. Numerical studies are presented to determine the design of this type of foundation. The proposed model offers significant savings in concrete and steel volumes compared to the current model, if the resultant force is located outside the central nucleus. Therefore, the proposed model should be used, because it offers better quality in the control of the resources used.
