WebJan 5, 2024 · Tutorial. A truss is a structure that consists of a collection of structural elements connected at pin joints or nodes. In theory, the pin joints provide no rotational resistance and behave as hinges. In practice, this is not always the case. The benefit of a truss is that the members are predominantly axially loaded. WebDec 31, 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.
