“…Zheng et al [41] highlighted the importance of hole geometries in PBL shear connectors for shear capacity evaluation and investigated the performance of circular and long-hole PBL ribs through pushout testing. Fan and Zhou [42] proposed a new PBL connector, perfobond hoop (PBH), comprising PBL with stirrups embedded in the hole for steel-concrete composite arch elements, particularly for bridges. The experimental results showed the better mechanical property and higher shearing capacity of perfobond hoop than PBL connectors.…”

Shear connectors are devices that provide shear connection at the interface of steel girders and reinforced concrete slabs in composite structures to accomplish composite action in a flexure. The seismic response of composite structures can be controlled using properly designed shear connectors. This state-of-the-art review article presents considerable information about the distinct types of shear connectors employed in composite structures. Various types of shear connectors, their uniqueness and characteristics, testing methods and findings obtained during the last decade are reviewed. The literature, efficacy, and applicability of the different categories of shear connectors, for example, headed studs, perfobond ribs, fibre reinforced polymer perfobonds, channels, pipes, Hilti X-HVB, composite dowels, demountable bolted shear connectors, and shear connectors in composite column are thoroughly studied. The conclusions made provide a response to the flow of the use of shear connectors for their behaviours, strength, and stiffness to achieve composite action.

“…Herein, a modified formula for calculating shear capacity was also proposed by considering rib height and spacing (Ahn et al, 2010). On the basis of the PBH connector extracted from the mechanical properties of the PBL shear connector (Valente and Cruz Paulo, 2004; Zhan et al, 2020; Zhou, 2014), a simplified formula of PBH was presented by the method of shear friction theory and multiple linear regression analysis (Li et al, 2019). First and foremost, according to the failure modes between the nail legs and connecting member materials, Hu derived the estimation equation of PBL shear connectors from critical transverse loading (Hu and Zhang, 2021).…”

The paper study the shear bearing performance and failure mechanism of perfobond leiste (PBL) shear connectors after hydrochloric acid corrosion. Seven groups of specimens with PBL shear connectors were designed, these PBL shear connectors suffered from hydrochloric acid corrosion time of 0 h, 1 h, 4 h, 12 h, 24 h, 48 h and 72 h. Herein, loading process, shear bearing capacity, load-slip curve, and failure mode were obtained by the push-out experiment, and then refined the finite element model (FEM) was established. Following the parameter analysis of 14 experiment specimens and 77 finite element models, the force mechanism of PBL shear connectors after hydrochloric acid corrosion were analyzed. With the extension of the corrosion time of PBL shear connectors, the shear capacity, deformation capacity, and slip decrease gradually. Among them, the finite element parameter analysis of PBL shear connectors demonstrates that their shear bearing capacity has the ability to be modified by raising the concrete strength, the diameter of penetrated steel bar, the diameter of steel plate holes, and changing the end bearing mode. On condition that the concrete strength is raised from C30 to C60, the shear capacity is reduced by 5.19%. When the diameter of penetrated steel bar has mushroomed from 12 mm to 25 mm, the shear capacity declines by 9.59%. Meanwhile, the shear bearing capacity of the end bearing is about 2 times of the non-end bearing. Once the diameter of steel plate holes adds 35 mm to 65 mm, the shear capacity just decreases by 2.48%. Finally, the reliability of PBL shear connectors are analyzed by the exit experiment data and the shear bearing capacity formula of PBL shear connectors. The research results can offer a reference for the shear bearing capacity of PBL shear connectors after hydrochloric acid corrosion.

“…Shear connectors are the pivotal elements that bond the steel beam to the concrete slab. Stud and Perfobond Leiste (PBL) shear connectors are mostly used in engineering thus far [1]. Stud shear connectors can resist longitudinal shear force through the stud rod, and a large part resists the lifting force of the concrete slab.…”

For steel–concrete composite structure, a new type of stud–PBL composite shear connector can improve the shear resistance of steel–concrete interface, and polypropylene fiber ceramsite concrete can reduce the self-weight. Therefore, investigating the shear behavior of stud–PBL composite shear connectors for steel–ceramsite concrete composite structures bears significance. In this study, static testing and numerical simulation of the composite shear connector push-out specimen of polypropylene fiber ceramsite concrete were first conducted. The influencing factors of the shear bearing capacity were then analyzed. The formula for determining the shear bearing capacity of the steel–ceramsite concrete composite structure stud–PBL composite shear connectors was ultimately established. The results indicated that the new composite shear connector exhibited excellent shear resistance and good deformation ability. In addition, increasing concrete’s strength, stud’s diameter, and perforated plate’s thickness could significantly improve the shear bearing capacity of the composite shear connector. The calculated value of the shear bearing capacity of the composite shear connector was well correlated the measured value of the test. Overall, the stud–PBL composite shear connector could effectively improve the interfacial shear bearing performance of the steel–ceramsite concrete composite structure. Moreover, the established formula demonstrated broad applicability.
