“…Izadi et al (2019) used a method for strengthening fatigue cracking of steel truss bridges with Fe-SMA, and verified its applicability and feasibility using fatigue test. Yuan et al (2019d) and Wang et al (2019l) adopted UHPC as the structural layer to investigate the enhancement effect of light composite bridge deck structure. Kinoshita et al (2019a) strengthened the welded joints of steel bridge with ultrasonic impact method, demonstrating that ultrasonic impact could effectively decrease the stress concentration of the welded joints, reduce the local microscopic defects of the weld toe at welded joints and welding residual stress, and significantly improve the fatigue resistance of the welded joints of the steel bridge.…”

“…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.

“…Concrete cracks occurred, and the bottom flange of the T-shaped ribs yielded first under the concentrated load in the midspan sections of the steel-concrete composite (SCC) deck [9]. e modified overlay significantly reduced the average stresses in the longitudinal rib deck of the sandwich plate system (SPS) and reactive powder concrete (RPC) system [10]. A pultruded fiber-reinforced polymer (FRP) shell was proposed for a concrete composite bridge deck, revealing that the prestressed FRP shell produced camber and significantly reduced the deformation under a construction load [11].…”

Composite bridge decks consisting of steel plates and concrete are used to minimize fatigue cracking and damage of asphalt pavement of orthotropic steel bridge decks subjected to wheel loads. This paper presents a methodology to optimize the parameters and mechanical performance of a corrugated steel plate-ultrahigh-performance concrete (UHPC) composite bridge deck with panel zone (PZ) shear connectors using the improved non-dominated sorting genetic algorithm (NSGA-II). A 3-D finite element model is established in ANSYS Workbench software to conduct numerical parameter analysis, and ABAQUS software is used to analyze the optimized model’s mechanical performance. The results show a significant improvement in the mechanical performance of the optimized composite bridge deck, with a 27.66% decrease in the maximum stress in the UHPC layer. The vertical displacement of the optimized composite bridge deck increases sharply when the load reaches 90% of the ultimate load, and a significant change in the strain is caused by the sliding displacement between the UHPC layer and steel plate. The bottom part of the corrugation yields first in the middle span, followed by failures of the ribs. In addition, as the tensile stress increases, damage occurs first in the UHPC layer near the PZ shear connectors in the shear bending area and the bottom in the bending area, expanding significantly to the entire bending and loading areas. The results indicate that the parameter optimization of the corrugated steel plate-UHPC composite bridge deck using NSGA-II improves the structure’s bending performance.
