A two-phase sequence of weight minimization is proposed as an approximate method for optimizing truss geometry and topology in preliminary design. In the first phase, the initial geometry is held fixed while member sizes are optimized. In the second phase, the nodal coordinates are optimized. The advantages of the heuristic method lie in reducing the number of structural analyses and in the control it offers the designer. Through the proposed technique, a reasonable initial geometry may be obtained which allows optimization of the topology of the structure.
