Space truss systems are light and effective structural systems and are used for various structural purposes, such as long span roof structures or space reflectors, etc. In some applications, notwithstanding their high redundancy, high accuracy is required in realization of their shape and predetermined distribution of prestress.
In the paper, a simple analytical scheme for shape and stress control of general truss structures is presented. The scheme is based on the linear force method of analysis.
