How to Calculate Maximum Roof Truss Span. Calculating the roof truss span of a truss is usually not a task a typical DIYer would do themselves. Since each truss is built to the specifications of a specific project, it is impossible to calculate the span yourself. The best way to calculate a roof truss span is to use the roof truss span table below.Alpha [X]²;1288819 said: Yes, the numbers on the members in the diagram. I assume the numbers represent the forces in the members, and the colors represent compression/tension. As I said, you can calculate every force by looking at every node separately. Imagine you "cut out" the leftmost node.Method of Joints. The free-body diagram of any joint is a concurrent force system in which the summation of moment will be of no help. Recall that only two equilibrium equations can be written. ΣFx = 0 Σ F x = 0 and ΣFy = 0 Σ F y = 0.
