Research Abstract

This research focused on developing a novel methodology for a vibration-based damage identification technique on bridge condition screening in the time-domain using a moving vehicle on the bridge as an actuator. Diagnostic investigation undertaken directly from the change in the element stiffness is the fundamental concept adopted in this study for condition screening of bridges. The element stiffness index (ESI), which indicates the ratio of damaged flexural rigidity of the finite element of a bridge model to an intact element, is used as the indicator of the bridge-health condition. The ESI governing linear equation is subtracted from equations of motion of a bridge-vehicle interactive system based on a pseudo-static formulation. The ESI linear equation is solved using the Tikhonov regularization method as well as Total Least Square approximation. The damage identification technique is verified through a numerical simulation of a steel plate girder bridge idealized as a set of beam elements. Two simple bridge models for experimental study have been setup, and carried out moving vehicle test. The base-line model for the damage identification is now on considering by comparing with the experimental results. Theoretical study through numerical simulation even considering the responses contaminated by noises suggests the feasibility of the proposed method for bridge-health monitoring. Observations reveal that not only the suspected damaged member, but also severity of the damage are detectable using the proposed method. It also demonstrates that the vibration data obtained under a low speed vehicle might give a better identification result. Investigations through numerical studies presented in this paper suggest the feasibility of the proposed method for bridge condition assessment. They can provide a method for extending engineering choice in bridge health monitoring. Many tasks remain, however, to make this procedure applicable to practical situations.
