“…The theoretical model for calculating the flexural capacity of CBDs under hogging moment was established using the composite beam model considering the slip effect. The sample analysis showed that the use of anti-pullout connectors could achieve a rebar stress reduction exceeding 50% and produce a capacity decli-nation of only 6%, compared to the full composite CBDs, which would significantly reduce the theoretical crack widths on the concrete layer [61].…”

Keywordshigh-performance cementitious composites composite bridge deck orthotropic steel bridge deck flexural behavior crack resistanceThe orthotropic steel bridge deck (OSBD) has been widely used in recent decades, benefiting from its advantages of lightweight and easy assembly. However, the longitudinal and transversal stiffeners of OSBDs are connected to the top flange plate through dense welds, which will easily introduce fatigue cracks. Hence, the composite bridge deck (CBD) system was proposed, adding a concrete layer over a steel plate to increase the sectional stiffness of OSBDs and reduce the fatigue stress amplitude. Furthermore, some new materials with extraordinary properties such as ultra-high-performance concrete (UHPC) and engineering cementitious composites (ECC) were used to replace the normal concrete, to improve the bearing capacity and crack resistance of CBDs. In this review, four kinds of bridge deck systems with different structural types including OSBD, steel-concrete, steel-UHPC, and steel-ECC CBDs were discussed. The flexural performance of four systems under sagging and hogging moments was reviewed, and close attention was paid to the crack resistance of the CBD system. In addition, the shear connection used in the CBDs was concentrated, and the shear behavior of some connectors including studs, perforated rib (PBL), and modified clothoid (MCL) shape shear connectors was investigated. The CBD structure assembled by duplicate profile steel parts proposed recently was introduced and discussed.

“…Zhou et al [15] conducted model tests and a finite element analysis on the joints in a railway bridge, studying the force transmission mechanism and the influence of structural design parameters on the mechanical properties of the joint. Liang et al [16] conducted half-scale model tests on the joint between a steel-concrete composite beam and concrete beam in a large-span cable-stayed bridge. They established a finite element model to study the crack development law of the joint and proposed a new type of joint with an improved crack resistance performance.…”

In this study, a refined model of the Shanghai Damaogang Bridge’s (hybrid beam type) box deck joints is established. The correctness of the model is verified by construction monitoring. For the front and back bearing plates, the force performance of the joint members under the most unfavorable loads is investigated, and the force transmission mechanism is analyzed. The influence of the bearing plate thickness and the joints’ stiffness on the stress distribution of the joint members, the internal force of the joints, and the force-transfer efficiency is investigated by the method of controlling variables, and the optimal structural parameters of the nodes are also studied. The results show that, within the proximity of the back bearing plate, the thickness of the back bearing plate affects stress distribution in the joint. The increased stiffness of the welding studs makes the range of shear force along the bridge direction of the top and bottom welding studs larger, and the longitudinal distribution of welding stud shear force is more uneven. The concrete structure bears a higher proportion of the internal force in the joint compared to the steel structure.

“…A steel-concrete composite segment is set between the steel girder and the concrete girder, so that steel and concrete become a coordinated whole to ensure smooth transmission of the internal force. Because the hybrid girder makes good use of characteristics of steel and concrete and gives full play to their advantages, the mechanical performance, spanning capacity, structural layout and economic benefits of the whole hybrid girder are superior to those of steel or concrete structure alone [1][2][3][4][5][6].…”

A steel-concrete composite segment of a steel-concrete hybrid girder features a complex structure and generally encounters difficulties in positioning and temporary fixation. In view of this, this study explored the layout of survey control networks and put forward a method for observing deformation of a concrete box girder at the cantilever end at the steel-concrete composite segment based on Hanzhuang Grand Canal Bridge, Tai'erzhuang District, Zaozhuang City, Shandong Province, China. Moreover, a construction process for hoisting the steel-concrete composite segment was proposed and a temporary fixation device for the segment used with a hanging basket was developed.The key sequences of temporary fixation were researched, which could provide practical and technological reference for similar engineering.
