“…In this field, three main approaches have been found: design proposals, behavior studies and calculation methods. Design proposals are focused on the conception of new geometries or the distribution of materials that improve the behavior of SCCBs [15][16][17][18][19][20][21][22][23][24][25]. Behavior studies are centered on the application of experimental or numerical approaches to study the bridge response when submitted to fire [26][27][28][29][30], seism [31][32][33][34][35][36][37][38][39], fatigue [40][41][42][43][44][45][46][47][48][49][50][51][52], secondary torsion [53], vibrations [54][55][56][57][58][59], blasting loads [60], or other phenomena [61]…”

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.

“…(2) e maximum vertical displacement of the bridge deck increases sharply from 26 mm to 55 mm as the load increases to 90% of the ultimate value. In contrast, the maximum sliding displacement increases stably to 1.7 mm during loading due to the firm connection between the steel plate and UHPC layer by the PZ connectors.…”

“…Lu used experiments and numerical analysis to investigate the mechanical behavior of the Dongping Bridge deck structure and found that the overall sti ness of the composite deck slab was low [1]. Peng-Zhen et al [2] found that Perfobond Leisten (PBL) shear connectors exhibited good anti-fatigue performance, and the perfobond strips reached the yield strength before failing [2]. Shao and Cao [3] conducted a fatigue assessment of a lightweight steel-ultrahigh-performance concrete (UHPC) composite deck (LWCD) and observed that the shear stress ranges of the headed studs were lower than the fatigue strength [3].…”

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.

“…Initially, the CFH were observed only in composite beams, as a constituent part of shear connectors, called Perfobond [1]. However, several other applications have emerged over the years (Figure 1) [2]- [5]. Although there are several applications of CFH in civil construction, it is noted that a large part of the research that involve these elements was dedicated to studying not the CFH itself, but some structural arrangement (most often Perfobond connectors in composite beams) in which the CFH is a constituent part.…”

Since the development of perforated plate shear connectors, different formulations have been proposed to predict their shear strength. Most of these formulations were derived from standard push-tests on multiple concrete filled holes (CFH) specimens simulating specific steel-concrete composite beam applications. Aiming at a more general application of these connectors in composite structures and the understanding of the physical and geometric parameters that influence their shear strength, the present work evaluated the use of 12 different formulations to predict 92 test results of single-hole specimens extracted from the literature. Such tests were chosen because the single-hole configuration allows better isolation of the connection behavior which facilitates comparative analysis. The predictions were statistically evaluated, and it was considered that the best formulations were those that showed lower scatter of data and a correction factor closer to one. Also, it was investigated if the individual terms that constitute the formulations adequately describe or show relation to the mechanics that govern the connection. It was verified that the best statistically rated formulations were also the ones showing clearer relation to the connector mechanical behavior. Among the evaluated formulations, three were significantly better than the others for strength prediction, however, it was noted that they can be further improved by considering the influence of concrete confinement and plate thickness on the hole’s strength.
