“…It is noted that the second band gap has the largest attenuation effect of the three band gaps and that the frequencies that correspond to this band gap are within the dominant frequency band for steel bridge noise. [1][2][3] Figure 6(a) shows that flexural wave propagation at 200 Hz located outside the band gap can propagate successfully without attenuation. In contrast, flexural wave propagation at 450 Hz located in the second band gap can barely propagate along the PUSP (Figure 6(b)).…”

“…Bridge structural vibrations and noise caused by high-speed movement of heavy-duty train loads are becoming increasingly problematic. 1–3 Bridge vibrations not only reduce rail transit serviceability and reliability, but also have significant adverse influences on public comfort. Hence, it is important to effectively and efficiently control vibration and provide low-noise bridge designs.…”

To effectively and efficiently control vibrations in steel bridge decks, the flexural wave band gap and vibration attenuation mechanism are studied. The band structures and displacement fields of the eigenmodes at the band gap edges of infinite periodic U-rib stiffened plates are calculated. The calculation method is combining the finite element method with Bloch periodic boundary conditions. A scaled specimen test of a finite periodic U-rib stiffened plate is used to validate the numerical results. A comparison of results confirms that introducing the U-rib allows the periodic U-rib stiffened plates to yield several flexural wave band gaps. In the band gaps, flexural wave propagation is stopped and clear flexural vibration suppression is achieved. Furthermore, the effects of geometric parameters and structural schemes on the flexural wave band gaps are analyzed in detail. Finally, by analyzing a specific case, it is demonstrated that the flexural wave band gaps and vibration attenuation properties can be controlled. This provides a new approach to vibration and noise control in steel bridges.

“…The vibration and radiated noise associated with a bridge structure are closely related to the mass, stiffness, damping, and frequency response characteristic of the structure. 11 Thus, a series of vibration reduction methods have been presented for structural optimization design. These methods include increasing the mass, damping, and stiffness of the structure.…”

The broad application of steel and steel-concrete bridges has caused significant vibration and noise problems. Although the channel steel-concrete composite girder is a commonly used bridge type, the vibration transmission performance and structural optimization design (concrete deck, stiffeners, transverse connection components, etc.) from the perspective of vibration control have not been well studied. In this paper, experimental and numerical approaches are combined to investigate the dynamic properties of a steel-channel girder in the audible frequency range (20–2000 Hz). A steel-channel girder is tested via hammering. The effects of damping, stiffeners, and a concrete deck on structural vibration are evaluated using the finite element method. The experimental results indicate negligible differences in the vibration responses on a single plate, but large differences at different sections. The results are influenced by the effects of the distance and transmission path. The numerical results reveal that increasing the damping and stiffness (e.g., setting stiffeners) are both effective in reducing vibrations. Furthermore, increasing the stiffness has a more prominent effect on structural vibrations and their frequency dependence, whereas increasing the damping ratio can stably reduce structural vibrations. The simulation results indicate that installing a concrete deck is the most effective approach to vibration reduction, as it can decrease overall vibration by more than 10 dB. Vertical web stiffeners have stronger effects on vibration reduction than other stiffening countermeasures (e.g., transverse connection components and longitudinal bottom plate stiffeners).

“…Aiming at improving the fatigue performance of the rib-tocrossbeam joint, the reported research mainly focuses on such aspects as optimizing the shape of the cope hole [4,5,12,13]; using post-weld treatment to release residual stress and enhance the performance [14]; introducing the rigid cement-based material as pavement to improve the rigidity of OSD and decrease stress range at fatigue details [15][16][17][18][19][20][21]; introducing additional attachments to enhance local rigidity [3,22], etc. Zhu et al [13] investigated the stress behavior and fatigue performance of two types of cope hole geometry on orthotropic bridge decks based on simultaneous field monitoring and finite-element method analysis.…”

In orthotropic steel decks (OSDs), the rib-to-crossbeam joint is the most complex joint. When dealing with the intersection of the rib to the crossbeam, the prevailing approach is to design a cope hole in the crossbeam web. Nevertheless, the stress concentration induced by rib distortion makes this joint a fatigue-prone detail. Furthermore, the weld connecting the rib and the crossbeam heavily relies on the manual welding, which leads to high fabrication costs. In this paper, the possibility of canceling the cope hole is discussed. Calculation results of different modeling methods using solid elements and shell elements are first compared with experimental results. Then, several design parameters of an OSD without cope holes are investigated adopting the hot spot stress method. Based on the results of the parametric analyzes, optimized dimensions of the rib-to-crossbeam joint without cope holes are selected. The comparison of the models with and without cope holes is performed. Fatigue life assessments are conducted based on the influence surfaces of reference points predefined around the rib-to-crossbeam joint. Research results reveal that the most critical position for the rib-to-crossbeam joint without cope holes is at the curvature on the rib side. The radius of rib has a local influence on the points at the curvature. A larger radius could effectively lower the maximum stress range. The fatigue performance of the rib-to-crossbeam joint depends on the distribution of the tire load. Considering less fatigue-prone locations and reduced fabrication costs, the overall performance of the optimized rib-to-crossbeam joint without cope holes is better.
