Space Truss

Space trusses are three-dimensional structures with longitudinal members connected at their ends by frictionless hinges. Loads are applied only at the nodes or joints of space trusses, so the self-weight is allocated to each element at its two ends that connect to other elements of the truss. The constraints imposed on space trusses are unquestionably the same as those imposed on plane trusses. The only difference in the analysis of space trusses and plane trusses is that a space truss element has three nodal coordinates at each node, whereas a plane truss element has only two.
