A 2D grillage model requires both bending and torsional stiffnesses but no area as there are no axial load present. Fig: 2-D Grillage Model Bending in beams leads to torsion in beams at 90degree. For instance, grillages only take vertical loads at each node. Fig: Converting points loads to uniformly distributed loads.
