Document Summary
A truss is a structure composed of members that are connected by pins at their ends and are subjected to loads and reactions applied only at the joints. Pratt (shaped like an m in the middle) Howe (shaped like a w in the middle) Different truss types are chosen for different reasons including cost efficiency, load demand, available materials (and therefore cost), etc. Trusses are also classified by the relative location of the deck and the truss. Sometimes we can analyse super complex structures by taking into consideration how a similar truss would act. There are two ways that we can analyse trusses: With both method, we are making some assumptions a. b. c. d. All members are connected at their ends only. Loads and reactions are applied only at the joints. The centroidal axis of each member coincides with a straight line b/w the joints (members are perfectly straight)
