“…Angle profile can be used in L-and C-shaped angle connectors. Between these two, C-shaped angle shear connectors have better performance and high shear resistance [7][8][9][10][11][12][13][14].…”

This paper presents experimental studies to investigate the behaviour of stiffened angle shear connectors subjected to isothermal fire loading. Push-out tests were conducted on 48 specimens covering various geometries of stiffened angle shear. The specimens were initially heated at room temperature, which gradually increased to target temperatures, and loaded up to failure for the assessment of their shear resistance at high temperatures. The behaviour of these connectors at ambient and high temperatures was compared. Results showed that the full-length stiffened angle shear connectors exhibited higher shear resistance compared with the half-length ones, whereas the ductility of the half-length stiffened shear connectors was greater than that of the full-length ones; the connector fracture governed the failure mode. Although heating exerted a substantially destructive effect on the resistance of the shear connectors, it led to increased ductile behaviour.

“…Previously, Adaptive Neuro Fuzzy Inference was used to classify the prevailing parameters affecting the shear strength forecast for angle shear connectors developed in C and L [17]. The use of channel shear connectors embedded in lightweight concrete in composite structures and shows that lightweight concrete has a minor effect on the specimens' ductility and load displacement performance [2,18]. The shear transfer capacity of a precast concrete sandwich panel system consists of two prefabricated reinforced concrete wythes separated by a layer of wythe is influenced by the composite behavior/ action degree [19].…”

“…Basalt fiber reinforced polymers effectively served as a shear connector and longitudinal reinforcement. The panels reinforced with Basalt fiber polymers showed a distinct load Plateau after connector failure occurred, which gave warnings of failure over excessive deflections usually used to warn of failure in parts strengthened with FRP [18,21]. An appropriate estimation of channel shear connectors shear capacity at varying slip, web and thickness flanges, weight, and concrete compression strength [20].…”

This study investigates the structural behavior of precast lightweight sandwich panels with dimensions of (500 × 500 mm) and 120 mm height. Specimens consists of three layers: concrete face wythes (with thicknesses of 45 mm and grades of (80, 70) MPa) and high-density foam (with thickness of 30 mm) as a core material. Steel and carbon fiber shear connectors (rods and strips) were used in panels with angles of (45°, 60° and 90°). Three-point flexure load test was carried out on all panels. Obtained results were studied with predicted ultimate loads from ANSYS software and the theoretical extremes capacities of 0% and full-composite cases to evaluate the effects of changing components. Strength/weight ratio and degree of composite action were obtained to can judge the panels with effective parameter. It was found that adding carbon fiber strips has a high positive effect in degree of composite action. Steel bars shear connectors were the optimum shear connectors' type with high strength concrete. Carbon fiber strips and rods shear connectors were the best shear connectors' type with light high strength concrete. All properties of specimens enhanced with the decrease of the angle of shear connectors with both of steel and carbon fiber shear connectors. Angle of 45° is the optimum angle that resists the flexure load, obtaining high degree of composite action and high strength/weight ratio. It also obtained the highest percent of predicted ultimate loads from ANSYS software.

“…The shear resistance and ductility of the two types of connectors were primarily investigated using static and cyclic loadings. Tahmasbi et al (2016) [9] investigated the behavior of two shapes of angle shear connectors (C and L-shaped) embedded in solid concrete slabs experimentally and numerically. Finite element model (FEM) was built to simulate the behavior of these connectors by employing nonlinear behaviour using large displacement and damage plasticity.…”

This research presents an experimental program to study the effect of using angle shear connectors instead of the headed stud on the flexural behavior of composite beams under negative bending moment (NBM). Both the angle and headed stud shear connectors used in this study have the same cross-sectional area. Five composite beams were casted and tested using three-point load configuration to ensure the NBM effect. Different parameters were included in this study such as the type of shear connector, bond interaction (partial and complete bond interaction) and arrangement of angle shear connectors. Two proposals method were suggested for angle setting in this study to investigate the structural behavior of the composite section. It has been found that, in the case of single angle shear connectors, the ultimate strength decreased by 4.12% compared with samples with the headed stud shear connectors. The direction of the angle setting has been shown to affect the flexural behavior of the composite section.
