“…As in other studies, it is found that the method is influenced by the road profile and measurement noise. The authors compare the proposed method with wavelet-based and frequency-based damage detection methods in [61] to show its ability in the presence of a road profile.…”

Indirect bridge monitoring methods, using the responses measured from vehicles passing over bridges, are under development for about a decade. A major advantage of these methods is that they use sensors mounted on the vehicle, no sensors or data acquisition system needs to be installed on the bridge. Most of the proposed methods are based on the identification of dynamic characteristics of the bridge from responses measured on the vehicle, such as natural frequency, mode shapes, and damping. In addition, some of the methods seek to directly detect bridge damage based on the interaction between the vehicle and bridge. This paper presents a critical review of indirect methods for bridge monitoring and provides discussion and recommendations on the challenges to be overcome for successful implementation in practice.

“…These kinds of damage detection methods can be further refined by improving the quality of mode shapes. Li and Au carefully discussed the influence of road roughness and measurement errors on the extracted mode shapes. Oshima et al proposed to improve mode shapes by removing the road roughness measured by a laser distance meter.…”

Summary Efficient damage detection technologies are highly demanded in the maintenance of bridge structures. For this purpose, the authors have developed the active Tap‐scan damage detection method, which can extract bridge damage from the acceleration of a passing vehicle mounted with a shaker. Although this method can be efficiently implemented in a noisy environment with normal traffic, the damage detection accuracy could be deteriorated by the fluctuation of vehicle velocity, and the portability of the vehicle is impeded by the cumbersome shaker system. To solve these problems, this paper proposes a passive Tap‐scan damage detection method, which uses an automatic driving vehicle with specially designed tire treads to scan the bridge. Instead of using the shaker, the tapping force is passively generated by coordinating the vehicle velocity with the periodic pattern of the tire tread. The theoretical basis of this method is firstly established on the analysis of the interaction between a simply supported beam and a passing vehicle with tapping contact forces, as well as the analytical solution of the deflection of a damaged beam subjected to a unit point force. Then, in‐house experimental damage detection results of a simply supported aluminium box beam are reported to demonstrate the effectiveness of the proposed method.

“…Nguyen et al [6] proposed an approximate linear contact model, which defines that the wheel-rail force can be multiplied by the elastic compression and the contact stiffness at the contact point. e equations of motion can be coupled by integrated wheel-rail force into the stiffness matrix [7]. Zhai et al [1] and Sun et al [8] used the explicit algorithm [9,10] to solve the equations of motion with Hertzian nonlinear contact theory for simulating the wheel and rail contact.…”

The two-step composite time integration scheme is combined with the linear contact relation between the wheel and rail (termed the two-step method) to solve coupled vehicle-track dynamic problems. First, two coupled vehicle-track models with different degrees-of-freedom are constructed, in which a vehicle-track system is modeled as two subsystems and the interaction between the two subsystems is implemented via kinematic constraints. Then, the two-step method is applied in the models to simulate several cases, and the accuracy and efficiency of this method are discussed in comparison with additional methods of the Newmark family. Contact separation can also be simulated using the same scheme without causing spurious oscillations for large integration steps. The results indicate that track irregularities can cause wheels to momentarily lose contact with the track, causing large impacts between the wheels and rail. Additionally, with the increase of the running velocity, contact separation will occur more frequently. The adoption of the two-step integration method can ensure the accuracy of solutions and significantly increase the computational efficiency; moreover, the matrixes representing the model information will not change during the calculation process, so the substructure data exported from commercial finite element software can be directly adopted.
