Prestressing of Open-Web Structures

In the design of open-web trusses the axial stresses are usually calculated on the following assumptions: that: (1) all members are straight and free to rotate at the joints, which are assumed to act as smooth hinges; (2) all joints lie at the intersection of the centroidal axis of the members; and (3) all loads, including the weight of the member, are applied at the joints.
