“…ese activities can be preventive when related with the design of infrastructures preventing the possibility of damage [126] or corrective, with a repair approach. Focusing on the search in SCCBs, two main trends have been established: repair and renovation [127,128] and the evaluation of bridge conditions [129][130][131].…”

“…Alternatively, the authors have proposed different methods to assess bridge conditions, giving stakeholders infrastructure management data to make decisions regarding the maintenance of the bridge. Gheitasi and Harris [129], using a finite element model, assess the composite action that is still working in bridges with damage in the concrete slabs; this method allows us to evaluate if the structure needs maintenance or, on the contrary, it still has sufficient resistance capacity. In other studies, the authors proposed a decision-making method according to the data obtained by instrumented bridges that have corrosion damage on the steel beams [130].…”

Steel-concrete composite bridges are used as an alternative to concrete bridges because of their ability to adapt their geometry to design constraints and the possibility of reusing some of the materials in the structure. In this review, we report the research carried out on the design, behavior, optimization, construction processes, maintenance, impact assessment, and decision-making techniques of composite bridges in order to arrive at a complete design approach. In addition to a qualitative analysis, a multivariate analysis is used to identify knowledge gaps related to bridge design and to detect trends in research. An additional objective is to make visible the gaps in the sustainable design of composite steel-concrete bridges, which allows us to focus on future research studies. The results of this work show how researchers have concentrated their studies on the preliminary design of bridges with a mainly economic approach, while at a global level, concern is directed towards the search for sustainable solutions. It is found that life cycle impact assessment and decision-making strategies allow bridge managers to improve decision-making, particularly at the end of the life cycle of composite bridges.

“…Results show that longitudinal splitting cracks tend to appear on the concrete slab since the transverse splitting force in concrete slab below the large stud is larger than the small-headed stud. In addition, with respect to normal strength concrete (NSC) slabs, durability problems such as freeze–thaw cycles and various chemical problems still remain as a big challenge up to now (Gheitasi and Harris, 2015; Lachemi et al, 2007; Umphrey et al, 2007; Yang et al, 2018).…”

In this article, the static shear behavior of large-headed studs embedded in ultra-high-performance concrete was investigated by push-out test and numerical analysis. A total of nine push-out specimens with single and grouped studs embedded in ultra-high-performance concrete and normal strength concrete slabs were tested. In the testing process, only shank failure appeared without cracks occurring on the surface of ultra-high-performance concrete slab when the steel–ultra-high-performance concrete specimens reached ultimate shear capacity. The shear capacity of specimens with large studs embedded in ultra-high-performance concrete slab increased by 10.6% compared those in normal concrete, and the current design codes such as Eurocode4, AASHTO LFRD 2014, and GB50017-2003 all underestimate the shear capacity of such kind of steel–ultra-high-performance concrete composite structures according to experimental results. Numerical models were established using ABAQUS with introducing damage plasticity material model. The influence of stud diameter, concrete strength, thickness of clear cover, and spacing of studs on the static shear behavior was thoroughly investigated via parametric analysis. Based on the experimental and numerical analysis, the existence of wedge block and the decrease of axis force are beneficial for improving the shear capacity of stud shear connectors.

The main structural elements of reinforced concrete (RC) bridges deteriorate with time under such uncertain hazards as scouring and corrosive conditions. In this paper, a multi-hazard framework is proposed to assess the performance of bridges subjected to the main effective uncertain natural hazards during their lifetime. In this assessment, the uncertainties associated with the combined effects of multiple hazards including pier scour, earthquake, carbonation, and corrosion are considered. Therefore, for each of the hazards, their severity relationships have been extracted over time, and the effects of these hazards on concrete elements are presented as resistance dimming parameters. The annual and cumulative losses due to these hazards in unit currency are estimated using the life-cycle costs. For decision making, the present value of the expected cumulative cost associated with the retrofit or design scenarios is evaluated using a cost-benefit analysis. The results for a case study bridge, using the proposed framework, indicate the significant impact of the different scenarios on reducing the expected value of damages or incurred losses due to multiple hazards.
