“…is may be ascribed to the comparatively higher strength of the RAC and transverse rebar used in present tests. e characteristic slip for all specimens using RAC was far larger than 6.0 mm, which is the lower limit value for a ductile shear connector suggested in Eurocode 4 [27], indicating the favorable ductility of PBL using RAC in steel-concrete composite beams.…”

“…Various formulas for predicting the shear resistance of PBL embedded in normal concrete have been proposed recently [22][23][24][25][26][27]. e majority of these equations comprises four terms: bond e ects at the steel plate-concrete interface, transverse rebar resistance, concrete dowel resistance, and the end-bearing resistance.…”

“…In addition to the use of FE simulation, experimental studies on PBL connectors and the in uence of di erent parameters that a ect its shear sti ness, strength, and load-slip response were gradually established during the past few decades or so. Empirical formulas for predicting bearing resistance of PBL fabricated with normal concrete are commonly found in the literature [17][18][19][20][21][22][23][24][25][26][27]. e majority of published researches in this area has focused mainly on behavior of PBLs in composite beams fabricated from normal concrete or high-strength concrete ; however, very few were related to beams made of RAC materials [18,28].…”

In this paper, the use of recycled aggregate concrete (RAC) for the upper slabs in steel-concrete composite beams is proposed. Perfobond rib connector (PBL), a relatively new type of shear connectors, has been widely used to ensure composite action between the steel and concrete elements in composite beams. For the past decades, several studies on assessing the performance of PBLs have been conducted, but very few focused on the PBLs that are embedded in RAC slabs. is paper presents results of an experimental and numerical simulation study that focused on characterizing the behavior of PBL fabricated using RAC. In the experimental program, a total of six standard push-out specimens, divided into three groups, were fabricated and loaded to failure. Test results indicated that the ductility of the PBLs using RAC materials decreased as the perforated steel plate thickness decreased, while the PBL ultimate strength increased by 4.3% and 12.8% for steel plate thicknesses of 10.0 mm and 12.0 mm, respectively, as compared to specimens with 8.0 mm steel plate thickness. Finite element (FE) models for PBLs embedded in RAC were developed, and numerical results were validated by corresponding experimental results. An extensive parametric numerical analysis was conducted to assess the effects of different parameters such as transverse steel rebar diameter and perforated steel plate strength and thickness on the performance of such connectors. Numerical simulation results showed that the PBL ultimate strength obtained based on the perforated plate fracture failure mode increases linearly as the steel rebar diameter increases. Also, numerical results indicated that as steel plate strength and thickness increase, failure mode changes from steel plate fracture to rupture of reinforced concrete dowels. Furthermore, existing published analytical formulas for predicting behavior of PBLs were assessed via a comparison with experimental and numerical results developed in this study. e outcomes of this study contribute in providing fundamental knowledge in a new sustainable application of PBL in steel-concrete composite beams with RAC slabs.

“…(18) was modified from Eq. (7) which was developed for the evaluation of PBL with conventional concrete in steel-concrete joints, the related experimental results obtained by the third parties Wang et al [6], He et al [7], Su et al [8], Zheng [21], and authors' previous research [22] were introduced to assess the applicability of Eq. (18) to PBL using conventional concrete in steel-concrete joint in hybrid girders.…”

“…The results revealed that the shear resistance of a PBL in a twin configuration was about 80% of that of a single independent PBL and the connectors effectively transferred the forces in steel-concrete joint. Zheng et al [21] presented results from twenty-one push-out tests of PBL embedded in conventional concrete involving both hole diameter and shape. It was concluded that the shear stiffness of the connector was improved with the increase of hole diameter.…”

The use of Perfobond Leisten (PBL) shear connectors in building structures has attracted increasing interest. A new approach for using perforated steel plates in concrete‐filled steel tube (CFST) column splices was implemented in this study. The shape of the perforation opening in perforated steel plates is generally a circle, similar to that of PBL shear connectors. However, in this study, an oval‐shaped perforation was used to increase the double shear area of the concrete. A pull‐out experiment was conducted on perforated steel plates with oval‐shaped perforations in a CFST block to evaluate the tensile performance of the perforated steel plates. A total of 29 specimens were tested, and the pull‐out strengths of the perforated steel plates were determined and analyzed under passive confinement from the steel tube. The contribution of the stress transfer was discussed in terms of the double shear of the concrete in the perforation and the bond and/or friction between the surface of the steel plate and concrete. Formulas for determining the maximum pull‐out strength were also developed.
