WebAnswer: They are not always acting at the joints. But for analysis they are assumed to be applied to the joints. Self weight of a truss is a distributed load but the total load is divided … WebDec 4, 2013 · Each truss carries those loads which act in its plane and may be treated as a two-dimensional structure. • Bolted or welded connections are assumed to be pinned together. Forces acting at the member ends reduce to a single force and no couple. Only twoforce members are considered. • When forces tend to pull the member apart, it is in …
