Abstract

Identification of damage to structures in order to prevent their expansion or improvement is an important issue that has received much attention from researchers. In this experimental study, a triangular model was used to apply the embedded cracks using CNC on the laboratory beam-columns. The size of the elements is such that the effective length of the crack is located inside the element and from it has not been removed. To identify embedded cracks, a static data index was used for Euler-Bernoulli beam-columns under axial load. In this laboratory study, two simple beams models with single, multiple damages and different loading scenarios were used. In the first step, the laboratory horizontal displacements are recorded and then included in the index. Finally, a comparison of the laboratory and the numerical results have shown the performance accuracy of the static database index.
