abstract = "The dynamic responses of a wide-flange steel beam with artificially introduced cracks were studied analytically and experimentally. Frequencies, displacement mode shapes (DMS) and strain mode shapes (SMS) are determined in both the analytical and experimental analyses. Modal damping ratios are also extracted in the experimental study. The sensitivities of the modal parameters to the damages are studied and absolute changes in mode shapes were used to determine damage locations. Results show that the damage of a beam can be detected and located by studying the changes in its dynamic characteristics. SMS shows higher sensitivity to local damage than DMS does.",
