“…The ductility of the stubby Y-type perfobond rib shear connector with transverse rebar D16 was 45.1% greater than that with D13. According to the assessment criteria for ductility provided by Kim et al (2013), the ductility of the stubby Y-type perfobond rib shear connector with transverse rebar D16 was also 28.8% greater than that with D13. These results show that, when stubby Y-type perfobond rib shear connectors with identical rib sizes are used in composite frame structures, the structures with larger-diameter transverse rebars are preferable in terms of ductility.…”

“…Eurocode-4 [37] defines a shear connector as ductile if δuk > 6 mm. In addition, Kim et al [32] suggested using the ratio of the slip capacity and initial relative slip (δu/δ90) to estimate the ductility in the inelastic behavior region of a shear connector by considering initial stiffness. Moreover, Kim et al [35] proposed Equation (1) to predict the shear strength of a Y-type perfobond rib shear connector.…”

“…Based on both ductility evaluation methods, shear connectors with large-diameter rebars are preferable in terms of ductility. The variables applied to Equation (1) in [32] to evaluate the shear resistance are listed in Table 6. As a result, the shear strengths of SY-D13-M and SY-D16-M predicted using Equation (1) in [32] were 803.5 and 1082.6 kN, and the experimental results were 894.6 and 907.4 kN, respectively.…”

Shear connectors are used in steel beam-concrete slabs of composite frame and bridge structures to transfer shear force according to design loads. The existing Y-type perfobond rib shear connectors are designed for girder slabs of composite bridges. Therefore, the rib and transverse rebars of the conventional Y-type perfobond rib shear connectors are extremely large for the composite frames of building structures. Thus, this paper proposes stubby Y-type perfobond rib shear connectors, redefining the existing connectors, for composite frames of building structures; these were used to perform push-out tests. These shear connectors have relatively small ribs compared to the conventional Y-type perfobond rib shear connectors. To confirm the shear resistance of these stubby shear connectors, we performed an experiment by using transverse rebars D13 and D16. The results indicate that these shear connectors have suitable shear strength and ductility for application in composite frame structures. The shear strengths obtained using D13 and D16 were not significantly different. However, the ductility of the shear connectors with D16 was 45.1% higher than that of the shear connectors with D13.

Abstract:The conventional strengthening strategy on the connection between the steel pile cap and reinforced concrete footing requires a series of complicated processes such as the distribution of reinforcing bars, their anchorage into concrete, and the usage of shear keys. This study investigates the structural performance of steel pile caps strengthened with newly proposed perfobond shear connectors subjected to lateral loading. Test parameters include the type of perfobond shear connectors, infilled concrete depth, and the number of L-shaped steel plates. The applied load versus deformation curve is plotted for all specimens, and their failure modes are identified. The effects of the test parameters on the peak load are examined in this work. From the results of this study, it can be confirmed that the proposed perfobond shear connector can be utilized as an alternative to the conventional steel pile cap strengthening method using steel rebars.

This paper focuses on the Y type perfobond shear connectors of steel‐concrete composite beams with the aim to investigate the influence of the structural parameter of the connection to the resistance and ductility of the structures. The Y shaped shear connections are a new shape developed with the benefits of resisting a higher shear force by the transversal bars and a bigger area of the concrete dowels surrounded by the Y shaped plate. This type of shear connection has significant resistance against vertical separation. In this paper, an advanced finite element model for a push‐out test with a Y type perfobond shear connector has been developed and validated by the experimental test. The aim of this research is to investigate different parameters such as the concrete strength, perfobond yield stress, the existence of the transversal bars on the structural behavior. The results showed that the concrete strength has a major effect as using a higher concrete resistance gave a higher ultimate resistance with a higher ductility. The existence of the transverse bars shows a major effect on the ductility load level. On the contrary, the effect of changing the diameter of the bars on the ductility load level was slightly noticeable. While using deferent steel grades for the perfobond plate significantly affected the ultimate resistance, but not the ductility load level. In further studies more parameters will be checked, and a formula and a guideline could be developed for a design purpose.
