The beam supports are assumed to be pinned. The column supports can be either pinned or fixed.The program then sketches the structure to illustrate what is being analysed. The geometry of the structure is entered by the user entering co-ordinates for all 4 joint locations. Can model portal frame structures with two vertical supports of any length, and a beam of any length spanning between the two supports.The Spreadsheet includes the following functions The spreadsheet then returns the analysis results in the form of maximum and minimum values for each span and support, and generates charts to illustrate the analysis of the whole portal frame structure. This spreadsheet undertakes the analysis of a user specified portal frame consisting of two vertical columns supporting a beam.
