A method is presented for finding optimal prestresses of cable-supported frames as well as order of tensioning cables and removing temporary supports, which is refered to as construction order. The cable forces at the final state are first optimized, and the construction process is inversely traced. In the prestress optimization, prestresses of cables are modeled as external forces. Constraints are given for stresses and displacements of the frame. Two methods are presented for optimization of construction order of cable-supported frames considering constraints on stresses of the frame and cables. The globally optimal order is found by the dynamic programming approach. An approximate method is also presented based on a heuristic measure for selecting a cable or a temporary support at each step while tracing the inverse construction process only once.
