The present invention is a computer-implemented method for constructing the foundation of a building, comprising; receiving nodal data associated with the structure design; propagate, member data of the structural frame; analyzing, the member data of the structural frame and the nodal data; applying, a series of loads to the structural frame; generating, a deflection model of the structural frame; and determining, by one of more processors, if any of the members failed and determining the strengthening requirements for the failed members.
