A structural optimization of truss structures for damage detection is proposed. The procedure is based on a concept to improve the reliability and performance of damage detection with structural shape optimization. By the concept, the objective of the optimization problem for damage detection is to maximize the minimum component of damage indicators defined by the damage detection algorithms for all damage scenarios. The minimum rank update theory is applied to the damage detection algorithms for formulating the shape design procedure of structures. Numerical examples for a truss model have been demonstrated to examine the performance of detecting the damage of the optimum design. Finally, the validity of the concept and the improvement of the performance for detecting structural damages by the optimization have been confirmed.
