Abstract Although research on structural damage detection remains active, studies focused on damage detection theories using strain, numerical analysis, and the validation of these theories through practical experiments are still limited. Consequently, further research on the assessment and application of strain-based damage detection methods for structures is necessary. This paper presents a method to determine the presence and location of damage within a structure by analyzing changes in strain caused by damage. The proposed method identifies damage presence and location using a strain energy-based approach. The theoretical validity of this method was first evaluated through numerical analysis. Subsequently, strain data were extracted from a Mock-Up test using Strain Gauges, and the proposed method was applied to detect damage, confirming both the theoretical validity and practical applicability.
