Mode Shape-Based Damage Detection Method (MSDI): Experimental Validation

The main principle of vibration-based damage detection in structures is to interpret the changes dynamic properties structure as indicators damage. In this study, mode shape index (MSDI) method was used identify discrete damages plate-like structures. This based on difference between modified modal displacements undamaged and damaged state structure. order assess advantages limitations proposed algorithm, we performed experimental analysis a reinforced concrete (RC) plate under 10 different cases. MSDI values were calculated through considering single and/or multiple locations, levels damage, boundary conditions. results confirmed that can be detect existence estimate severity case
