Civil Engineering Structural Health Monitoring Bridge Monitoring Change in First Transverse Mode Method In recent years Structural Health Monitoring (SHM) has gained considerable attention in the engineering world. For bridge infrastructure, previous methods have focused on the detection of localized damage through manipulation of modal parameters extracted longitudinally along the structure. This paper improves upon previous methods by applying modal parameter extraction techniques transversely. Through application of modal curve fitting to transverse frequency response functions (FRFs), not only is local damage identified, but global beam damage is also identified. To present the effectiveness of the approach, modal parameters were extracted from acceleration data obtained from a finite element model (FEM). Analysis of the modal parameters showed that the proposed approach could not only detect both local and global beam damage, but could also differentiate between damage mechanisms using only one transverse mode shape. The proposed method was compared to a previously developed SHM method, the Uniform Load Surface-Curvature (ULS-Curvature) Method. 2012-09-11 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1339520527 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1339520527 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
