Members must be of constant cross section (E and I are constant for entire length).This program uses the "stiffness matrix" method of analysis and four (4) following basic analysis assumptions: Also, the frame is drawn for visual confimation of geometry/configuration.ฤก. Plots of both the shear and moment diagrams are also produced. Individual frame members are also analyzed to determine the shears and intermediate moments. Specifically, the "stiffness matrix" method of analysis is used to determine the unknown joint displacements, support reactions, and member end forces. 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.
