WebFeb 4, 2015 · FRAME is a spreadsheet program written in MS-Excel for the purpose of plane frame analysis of portal and gable rigid plane frames subjected to various types of loading. Specifically, the "stiffness matrix" method of analysis is used to determine the unknown joint displacements, support reactions, and member end forces. 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.
