“…The information extracted from BWIM systems can also be used for the purpose of SHM or vice versa. There have been some recent investigations on the use of BWIM systems for damage detection Carey et al, 2013;Zhu and Law, 2015) and determination of dynamic amplification factors (O'Brien et al, 2013;. In the future, more research can be focused on incorporating BWIM technologies into the SHM systems to further extend their applications and reduce the cost of SHM systems.…”

Weigh-in-motion technology is an effective tool that has been extensively used to monitor traffic on highways. Pavement-based weighin-motion systems usually have poor durability and will cause traffic interruption during their installation and maintenance process. The recently developed bridge weigh-in-motion technology provides a more convenient and cost-effective alternative to the pavement-based weigh-in-motion technology. Bridge weigh-in-motion systems can be installed without interrupting the traffic. Also, bridge weigh-in-motion systems have the potential to deliver better accuracy than pavement-based weigh-in-motion systems. Due to these significant advantages, the bridge weigh-in-motion technology has been playing an increasingly important role in bridge health monitoring and overweight truck enforcement, and many studies have been conducted to continuously improve the bridge weigh-inmotion technology. In this review, the common algorithms for bridge weigh-in-motion are discussed in detail, and the typical instrumentation of bridge weigh-in-motion systems is also introduced. Meanwhile, much effort is made to identify the remaining issues in the application of bridge weigh-in-motion technology, and the corresponding future research is proposed.

“…144 However, the measured bridge response can be significantly influenced by dynamic amplification of the bridge and axle vibrations. 92,93 This phenomenon limits the applicability of traditional B-WIM system where the bridge dynamic vibration is significant or cannot be filtered out. 92,98 Here comes the importance of developing dynamic B-WIM system incorporating the dynamic bridge information using equation of motion where dynamic components of bridge response constitute a significant cause of the prediction discrepancy.…”

Bridge health monitoring (BHM) has grown as an essential component of the maintenance paradigm in any transportation network around the world. The mostly used visual inspection method has limitations such as inspector bias, inaccessibility in remote areas, need for human physical presence at the bridge location, etc. On the other hand, vibration-based BHM methods require artificial excitation to the bridge. This motivates researchers to explore potential alternatives for BHM. The bridge weigh-in-motion (B-WIM) system has emerged as a promising alternative with the potential to augment traditional BHM techniques. The advantages of B-WIM systems are durability, portability, easy installation, etc. In addition to weight estimation of passing vehicles, it provides other structural informations that are helpful for bridge assessment. It also overcomes the limitations of pavement-based WIM systems. Most importantly, a B-WIM system uses the same components as a standard BHM system, making BHM a by-product and economical compared to a standalone BHM system. With the development of B-WIM theory, recent researches have revealed the feasibility of B-WIM system for BHM. However, the applicability of the B-WIM system for BHM in any type of bridge and condition is limited. Through the fundamentals of B-WIM theory, this paper reviews the existing bridge response-based BHM methods that involved B-WIM algorithm. The findings are discussed in order to identify the remaining challenges and provide insight to the future aspects.

“…A Moving Average Filter (MAF) is sometimes used to smooth out the road surface profile and to address the fact that tires spread out the weight of a wheel over a patch with finite area. Carey et al (2013) use an MAF with a length of 24 cm to take into account the tire contact patch, but this method can just filter the high frequency elements of the road profile -it better represents the excitation but not the response. In this paper, the authors integrate patch loads, For personal use only.…”

The influence of vehicle–tire contact force area on vehicle–bridge dynamic interaction

This paper proposes an updated vehicle-tire contact force model to simulate vehicle-bridge interaction, considering the tire contact area and the thickness of the bridge wearing surface. In contrast to the traditional methods of using a single-point tire contact force with a moving average filter, the proposed model uses multiple-point contact forces to account for the tire contact area. Results show that both the longitudinal and transverse distribution of tire contact force have a significant effect.
