Studies on truss design optimization have been conducted extensively over the past decades. One of the significant current discussions is the reliability aspect of truss design in addition to optimal design. This problem has become more important, especially the sizing and shaping in the optimization of truss structures. Reliability-based design optimization is defined as finding the optimum structure while satisfying the given uncertainty and reliability criteria. This study aims to investigate the performance of metaheuristic algorithm in optimizing the truss structure design and satisfying the reliability constraints. Latin hypercube sampling method was used to model the presence of uncertainty. Symbiotic organisms search was also utilized as a metaheuristic algorithm to solve a modified 15-bar planar truss. The results indicated that reliability design gives a significant result in the shape and size of truss.
