자유 진동 해석과 유전 알고리즘을 이용한 트러스 구조물 손상 탐지

This study identifies the damage location and extent of truss structures by using free vibration analysis and genetic algorithm (μ-GA). To describe the damage in truss structures, the modulus of elasticity of some specific elements is reduced. The damage location and extent is detected by comparing natural frequency healthy truss structures with damaged truss structures using micro genetic algorithm. In this study, some numerical examples are modeled and confirmed the damage location and extent by using micro genetic algorithm.
