Abstract:
A simple plane frame model is described for the lateral load analysis—static and dynamic—of frames in multistory buildings including biaxial load effects. By taking advantage of the shear force-axial force and the torque-bending moment analogies it is possible to model the spatial behavior of the structure, and to consider the combined effects of bidirectional shear due to lateral and torsional displacements on columns pertaining to two orthogonal frames. A numerical example is given.
