“…With the process of automated welding technology, China has developed an automated U-rib internal welding technology with independent intellectual property rights and proposed a double-sided welding method for rib-to-deck welded joints. This technology has now been widely used in such major construction projects as the Zhuankou Yangtze River Bridge, the Zhaoqing Xijiang Bridge, and the Shenzhen-Zhongshan Link [23][24][25][26]. Da et al compared the difference in stress response between single-sided rib-to-deck welded joints and double-sided rib-to-deck welded joints under vehicle loads through finite element analysis.…”

“…The results showed that the single-sided rib-to-deck welded joints had greater stress concentration at the welding roots [23]. Cui et al studied the fatigue properties of double-sided rib-to-deck welded joints with small-sized specimens and showed that they had high fatigue strength [24]. Yang et al evaluated the fatigue properties of single-sided rib-to-deck welded joints and double-sided rib-to-deck welded joints with the structural stress method [25].…”

The fatigue cracks of rib-to-deck welded joints in an orthotropic steel deck are one of the critical conundrums that restrict the sustainable development of steel bridges. Double-sided welded joints were achieved by introducing internal welding technology to overcome the initial “crack-like” manufacturing defects at the welding roots of single-sided welded joints. Through the observation of the macro-section of the welded joint, the differences between single-sided welding, partial-penetration welding, and full-penetration welding in rib-to-deck welded joints are compared. Relying on the Shenzhen–Zhongshan link, the fatigue failure and mechanism of single-sided rib-to-deck welded joints are clarified by the nominal stress and structural stress methods, and those of double-sided welded joints were determined through fatigue tests. The fatigue strength of rib-to-deck welded joints is higher than the FAT90 of Chinese standard and the FAT C joints of American standard. The fatigue strength of double-sided rib-to-deck welded joints is significantly higher than that of single-sided welded joints. The fatigue strength of rib-to-deck welded joints is within a ± 2σ range of main S-N curves by the structural stress method. It is suggested to adopt the double-sided welded joints in practice, and to ensure that the penetration rate is beyond 80%. The trial data are limited, and further tests are needed to confirm the results.

“…The local bending vibration of large-area components in steel bridges is the main source for the structure-borne noise (Alten and Flesch, 2012). The stiffened plate is one of the primary components in steel bridge (Cui et al, 2022; Marczak et al, 2021; Pham et al, 2021). This kind of plate has dense bending modes at mid-high frequencies and directly withstands the external energy input.…”

This study presents a novel method for analyzing the vibration and noise from the periodic rib stiffened plate (PRSP). For the first time, the band gap theory was combined with hybrid finite element-boundary element method (FE-BEM) to predict the vibro-acoustic characteristics of this structure and guide its vibration and noise reduction design from the perspective of bending wave propagation. The excitation test was carried out simultaneously to verify the rationality and accuracy of the proposed method. Then, the acoustic contribution analysis was conducted and the influence of structural design parameters on bending wave bandgap and noise reduction effect was discussed in detail. The results show that there are alternating passbands and stopbands for bending waves propagating in PRSP, making the vibro-acoustic responses in different frequency bands exhibit distinct differences as well. Increasing the base plate thickness and decreasing the rib spacing are conducive to widen the bandgaps and reduce the noise radiation, which are the decisive factors affecting the vibro-acoustic characteristics of PRSP. While the rib thickness has little effect, this provides a new approach for vibration mitigation and acoustic optimization in steel bridges.
