Trusses Calculations

The next spreadsheets will help you to verify forces calculations on your bridges. You have spreadsheets for the Warren Truss, the Pratt Truss, and for the Howe Truss. Only type the magnitude of the load applied on the corresponding truss node, the truss elements' length, and the non-horizontal elements angle.

You will see on the spreadsheets, The moments produced by the loads, the matrix corresponding to the analysis of forces on every node, its inverse matrix, and the compression- tension forces on every element of the truss
