“…Shao et al [20] proposed a composite deck system composed of orthotropic steel deck, ultrathin UHPC layer and asphalt pavement. The relevant model experimental study and theoretical calculation were conducted on the behavior and fatigue performance of this composite OSD system [21][22][23][24][25]. The study results showed that the UHPC layer significantly enhanced the rigidity of the OSD system, reduced the stress level of steel deck plate and improved the mechanical behavior of asphalt pavement.…”

“…In addition, the UHPC layer exhibited superior fatigue performance and durability, which efficiently reduced the lifecycle cost and environmental influence of the bridge. Even though the UHPC composite OSD system has already been applied in some actual bridges, it is necessary to carry out some in situ tests which directly indicate the behavior of the OSD bridges [23,26].…”

A novel ultra high performance concrete (UHPC) layer composite orthotropic steel deck was adopted in the construction of a new bridge in China to improve the fatigue performance of the orthotropic steel deck plate and reduce the disease of surface wearing layer. In situ experiments were conducted to study the UHPC layer’s impact on the behavior of the orthotropic steel deck. The test vehicle loads were applied on the deck plate before and after UHPC layer paving, the stresses where fatigue cracks usually occur and the deflections of critical sections were measured. The test results verified that the UHPC composite steel deck system could significantly reduce the stress of the rib-to-deck connection region and the stress at the bottom toe of rib-to-diaphragm weld. In addition, it slightly influenced the performance of U shape rib, girder web-to-deck and diaphragm cutout.

“…At present, research on the effect of the wheel position on the fatigue performance of bridge decks mainly focuses on steel decks [33][34][35][36][37]. For example, Zhou et al [34] showed that the lateral position of a vehicle was very sensitive to the transverse stress of the steel bridge deck and the fatigue damage of key parts.…”

“…Zeng et al [35] showed that the cumulative effect of plastic deformation should be considered when analyzing the fatigue damage of the steel deck under a vehicle wheel load. Zhu et al [33] studied the stress behavior and fatigue life estimation of the composite system of orthotropic steel deck (OSD) and ultrahigh performance concrete (UHPC) under concentrated wheel load by means of field monitoring and finite-element analysis. e results indicated that the stress value corresponding to the fatigue detail was sensitive to the transverse position of a single wheel load.…”

The fatigue performance of the bridge deck significantly affects the safety and durability of the overall steel-concrete composite beam bridge. Based on the vehicle flow information of the highway within 10 years, the fatigue performance of a two-way four-lane steel-concrete composite continuous beam bridge deck is studied in this research. The results indicate that the effect of the wheel track position is negligible for two-way four-lane bridge when the wheel track sways laterally, and the fatigue stress of bridge deck concrete is the most unfavorable while the loading position is 7.0 m away from the bridge center line. The fatigue damage decreases by 30%–40% when the centerline of the lane deviates from the most unfavorable stress position by 1 m. The punching fatigue of the concrete is more sensitive to the changes in slab thickness, and the thickness of the deck concrete slab is recommended to be ≥35 cm.

“…Dieng et al (2013) used ultra-high performance fiber reinforced concrete (UHPFRC) to renovate existing bridge decks, whereas the flexural strength of UHPFRC was largely affected by the direction of fibers. Recently, a steel-UHPC (ultra-high performance concrete) composite bridge deck has been proposed to reinforce the cracked orthotropic deck (Shao et al, 2013; Zhu et al, 2018b). Steel-UHPC composite bridge decks have been successfully used for small and medium span bridges, but no reports are available for long-span cable-stayed bridges.…”

Fatigue cracking induced by vehicle load is a prevalent problem in orthotropic steel decks. In addition, pavement debonding in steel bridge decks is another familiar issue resulting from low slip resistance in the faying surface between the steel and asphalt concrete. The present study proposed a strengthening method that uses ultra-high performance concrete to stiffen a repeatedly maintained cable-stayed bridge in order to help address these two problems. The existing issues of the real bridge and the corresponding causes were investigated. Following this, an ultra-high performance concrete paving system was designed to improve the stiffness of the orthotropic steel decks. For this paving system, a 45-mm ultra-high performance concrete layer was connected to the deck by welded shear studs. The local stresses at the typical vulnerable fatigue cracking points were determined by means of a finite element model and of a field loading test to evaluate the strengthening effect. The results showed that this strengthening method can prevent the propagation of fatigue cracks. The local stresses of the U-ribs and diaphragms were reduced by 45.4% and 40.0%, respectively. The repaired bridge has sufficient resistance against fatigue cracking based on the in situ observations.
