“…Zheng et al proposed a long-hole-type PBL connector and a slotted-type PBL connector while considering the hole’s structure to improve the shear-bearing capacity of the connector and facilitate construction. Zheng et al verified that the connector had good shear and pullout resistance based on push-out tests, numerical simulations and parametric analyses, respectively [ 36 , 37 , 38 ]. In particular, in order to ensure the ductility of shear connectors, the deformation and slip capacity of shear connectors were improved.…”

In order to improve the shear resistance and structural ductility of the perfobond rib (PBL) connector, a new PBL connector with steel–rubber tenon is proposed in this study, which aims to increase the shear load capacity of the connector while improving the ductility of the connector. First, models of new PBLs are established based on the validated finite element method, and their mechanical properties are compared with other shear connectors. The results show that the stiffness and shear load capacity of the proposed connector can be effectively improved when the steel ring is added, where the shear stiffness can be reduced, and the deformation capacity of the specimen can be improved when the rubber ring is added. When a steel ring with a thickness of 5 mm and a rubber ring with a thickness of 5 mm are involved, the shear load capacity of the connector with steel–rubber tenon is increased by 13.7%, and the shear stiffness is reduced by 37.3% compared to the conventional concrete tenon connector, while the ductility is increased by 75.1% compared to the connector with steel ring tenon. Subsequently, as for the connectors with steel–rubber tenon, the effects of the thickness of the steel ring, the thickness of the rubber ring, the diameter of perforated rebar, the strength of concrete and the strength of perforated steel plate are analyzed based on the finite element model of a PBL. The results show that an increase in the thickness of the steel ring, the diameter of the perforated rebar and the strength of the concrete will cause an increase in the shear stiffness and shear load capacity of the connector; however, an increase in the thickness of the rubber ring can cause a decrease in the shear stiffness and shear load capacity of the connector, while a change in the strength of perforated steel plate has little effect on the shear stiffness and shear load-carrying capacity. Finally, based on the finite element parametric analysis results and the damage mechanism of the proposed connector, a calculation equation applicable to the PBL connector with steel–rubber tenon is presented to predict the shear load capacity of the connector.

“…The use of steel-concrete composite structures in civil engineering has seen rapid growth in the past decades due to their excellent mechanical properties, convenient construction performance and outstanding economic features [ 1 ]. In order to fully utilize the respective properties of steel and concrete, it is necessary to resist the slip between steel and concrete through shear connectors to ensure a reliable connection between the two materials [ 2 ]. As the most commonly used shear connectors for composite structures, headed studs have the advantages of good ductility, simple preparation and easy construction, but also have the disadvantages of insufficient fatigue performance and harsh requirements for installation equipment [ 3 , 4 ].…”

Perfobond rib (PBL) shear connectors, made up of the perforated steel plates with the penetrating rebars passing through the holes, are extensively adopted in steel-concrete composite structures for their excellent performance. The adequate understanding of mechanical properties for PBL connectors is of great significance for their reasonable design. In this study, a push out experiment, including 12 specimens with the parameters of concrete strength, diameter of penetrating rebars and the number of holes on perforated steel plate, was performed to explore the mechanical behavior of PBL connectors with steel fiber high strength concrete (SFHSC). The experimental results showed that the shear capacity of the PBL connectors increased with the increase in concrete strength, diameter of the penetrating rebars and the number of holes. Furthermore, a general prediction formula for the shear capacity of PBL connectors was developed, which considers the shear contribution of concrete dowels, concrete end-bearing, interfacial bonding between the perforated steel plates and concrete and the penetrating rebars as well as the enhancement effect of steel fibers. The prediction results of the equation are in good agreement with the experimental data and could provide a reference for the design of PBL connectors.

“…In this special issue, four papers investigate the behaviours of novel prefabricated structures using experimental and numerical approaches [46][47][48][49]. On the other hand, several innovative structural forms are invented and the behaviours of those structures are presented and discussed in four other papers [50][51][52][53]. Two structural strengthening techniques using composite and shape memory alloy materials for the reinforced concrete structures are proposed and studied [54,55].…”
