Behavior of V-shaped angle shear connectors: experimental and parametric study

Abstract

In this paper a new shear connector called V-shaped angle shear connector for steel-concrete composite system is proposed. This shear connector was proven to improve some mechanical properties of shear connectors, including high shear transfer, uplift resistance, sufficient ductility, and strength degradation resistance under cyclic loading, as well as to being cost effective compared with similar shear connectors, such as C-shaped channel and angle shear connectors. A total of 14 push-out tests were performed on composite beams with these connectors under monotonic and low cyclic loading. The failure mode, shear resistance, and ductility of the push-out specimens were investigated. The study also comprises of finite element and parametric analysis using an effective numerical model of the experimental push-out tests using the program ABAQUS. The finite element models were validated against the test results presented in experimental tests. Results showed that V-shaped angle shear connector has excellent behavior in terms of both shear strength and ductility. In addition, high resistance under cyclic loading was exhibited since the shear resistance of this connector was almost similar in both monotonic and cyclic loadings. Finite element results show good agreement with experimental results. The results discussed on the ductility and strength of this connector with different size and slope of inclination. In addition, the channel and angle shear connectors were compared with V-shaped angle shear connectors. V-shaped angle shear connectors behave much better than other similar connectors, such as normal angle shear connectors, and are superior to channel shear connectors in most specimens.

Experimental Study and Finite Element Modelling of Push-Out Tests on a New Shear Connector of I-Shape

“…Recently, several authors have proposed new types of shear connectors, such as Y-type perfobond rib connector [1], J-hook connector [2], Bolted connector [3], Rubber-sleeved stud [4], and V-shaped angle connector [5]. In this context, a new shear connector, called I-shape connector is proposed.…”

Fire performance of headed shear studs in profiled steel sheeting

“…Conversely, the effect of the deck thickness decreased when the stud location was moved to a favourable position in the rib deck because the failure mode changed from rib punching to concrete pull-out. Numerous experimental and numerical studies have been conducted regarding the characteristics of shear connections in ambient conditions [7][8][9][10]. However, to the best of our knowledge, few researchers have addressed the effect of temperature on shear connections, especially with regard to a transverse deck.…”

“…Moreover, it is known from numerous experiments and finite element analyses (FEAs) that the strength of a shear stud is influenced by its cross‐sectional area, height, and tensile strength and the elastic modulus and compressive strength of concrete . Furthermore, the failure modes of shear studs have been observed, and the load transfer through shear studs has been studied through static and fatigue tests . The relative displacement and initial tangential stiffness have been compared and analyzed based on the results of the statistical analysis of the load–displacement curves obtained from static tests …”
