“…Experimental work by the same authors confirms the findings of their earlier theoretical study using a cart fitted with accelerometers towed behind a light commercial truck (Lin and Yang, 2005). A follow up theoretical study by the same research group examines the relative influence of the different dynamic parameters of the system on successfully identifying the bridge frequencies of concern (Yang and Chang, 2009). McGetrick et al (2009) show that vehicle accelerations can be employed to identify not only the bridge frequencies but also changes in the structural damping.…”

Previous research on damage detection based on the response of a structure to a moving load has reported decay in accuracy with increasing load speed. Using a 3-D vehicle-bridge interaction model, this paper shows that the area under the filtered acceleration response of the bridge increases with increasing damage, even at highway load speeds. Once a datum reading is established, the area under subsequent readings can be monitored and compared to the base line reading, if an increase is observed it may indicate the presence of damage. The sensitivity of the proposed approach to road roughness and noise is tested in several damage scenarios.The possibility of identifying damage in the bridge, by analysing the acceleration response of the vehicle traversing it is also investigated. While vehicle acceleration is shown to be more sensitive to road roughness and noise and therefore less reliable than direct bridge measurements, damage is successfully identified in favourable scenarios.

“…The idea was first proposed by Yang et al [2] in which the fundamental frequency of the bridge is estimated from the acceleration response measured on a passing vehicle. Several researchers have now developed methods to identify the bridge fundamental frequency from the acceleration signal measured on a passing vehicle [3][4][5][6] and to prove the idea in an experimental case study [7][8][9]. In addition, several studies have been carried out to identify the bridge damping using the signal measured on a passing vehicle [10,11].…”

“…The feasibility of using such an indirect approach for bridge condition assessment and the extraction of bridge properties such as frequency, stiffness and changes in damping from the acceleration response of a passing vehicle has been verified theoretically using simulations of vehicle-bridge interaction (VBI) (Yang et al 2004, Bu et al 2006, McGetrick et al 2009, Yang & Chang 2009, Keenahan et al 2012) and its potential for bridge monitoring has also been highlighted in experimental investigations (Lin & Yang 2005, Kim et al 2011) and field trials (González et al 2008, Miyamoto & Yabe 2012). An important consideration for the successful implementation of this kind of approach is found to be the dynamic excitation of the bridge; it needs to be sufficiently high to overcome the relatively high influence of road roughness on the vehicle response.…”
