Abstract :In this work, damage detection insert ignore into journalissuearticles values(DD); method for beam structures subject to moving load is proposed. DD is formulated as an optimization problem and solved for crack locations and depths using three versions of the particle swarm optimization insert ignore into journalissuearticles values(PSO);. It was observed that PSO with constriction factor is superior in the sense of convergence speed and robustness. Also, it was experienced that small cracks with depth ratio of 0.15 can be identified by the present method in spite of 3% noise interference. The proposed method is demonstrated to be better than wavelet transform method at higher moving load speeds
