Early Structural Damage Assessment by Using an Improved Frequency Evaluation Algorithm

Abstract This paper introduces a method to identify damages in beam-like structures by analyzing the natural frequency changes of the first six transversal vibration modes. A correlation between the damage location and frequency change is established for each mode separately, by considering the moda...
