The Design of Trusses and its Influence on Weight and Stiffness
It is shown that weight can be saved, and stiffness gained by a proper choice of the design, that is the type of frame of any truss. A method is developed first to choose the best among several statically determinate designs. It is then demonstrated that, when a redundant truss has to carry one set of loads, it is always possible, by the removal of some bars, to get a statically determinate truss which is lighter, for the same ultimate stress. But the redundancy keeps its advantages when the structure has to carry several sets of loads in turn.
