“…The efficacy of their technique is underscored by an impressive damage detection accuracy rate of 96.62%. Nick et al [64] introduced a novel two-stage damage detection approach tailored for steel frameworks, employing ANNs. This method accentuates the utilization of adjusted damage indices, derived from modal flexibility and strain energy to first pinpoint the locations of damage.…”

“…Theoretically, the proposed method can accurately calculate the structural damage parameters only by using the first-order eigen-parameters of structural free vibration. From Equations ( 24) and (25), one can find that the system matrices K and M of the undamaged FEM are used in the computation of the frequency-shift flexibility sensitivity. However, Equation ( 25) can be approximated by using Equation (20) with a few lower-frequency vibration modes.…”

“…The damage index proposed by them is particularly sensitive to the damage location and can be successfully applied to the steel truss bridge with different damage patterns. Nick et al [25] proposed a damage index based on modal flexibility and modal strain energy, and a two-stage multi-criteria damage detection method using an artificial neural network (ANN) to locate and quantify the damage of steel frames. The modal flexibility matrix was obtained by the first three bending vibration modes.…”

“…The damage indices are computed using the mode shape components and their resultants to improve the precision and effectiveness of damage identification. The MSEDI-based ANNs predicted the damage magnitudes of the single and multiple damage scenarios with errors of up to 0.95% and 1.12%, respectively (Nick et al, 2023). Steel column bucking resistance was examined using finite element analysis and validated using an artificial neural network.…”
