WebAnalysis Methods for Buildings Frames 1. Force Method It is also called flexibility method or method of consistent deformation. Used to compute internal forces and reactions in statically indeterminate structures. It is suitable for analyzing statically indeterminate frames that have a single storey and uncommon geometry such as a gabled frame. WebA portal frame usually involves high degrees of indeterminacy. Therefore, there are always a large number of partial and complete collapse mechanisms (sometimes termed basic mechanisms) that can be combined to form new collapse mechanisms with some plastic hinges becoming elastic (unloading) again.
