Web31 dec. 2024 · To calculate the compression and tension forces of the truss members with the 3 equilibrium equations, we do another approximation. The Line load of 200 kN/m is approximated as point loads in the nodes, because otherwise the bottom chord members would be beams instead of bars, which makes the calculation a lot more difficult.

WebThe major difference is the placement of the diagonal beams as one goes towards the middle and the other truss goes away from the middle. Warren Truss. Howe Truss. Pratt Truss. When determining which truss is best for a project, it is generally best to look at the weight of the bridge, the length of the bridge as well as the anticipated traffic.
