“…Most of the recent studies of effect of fire have been evaluated on the headed stud and Profobond shear connectors. Quevedo and Silva, 2013 [8] performed FE modeling of headed stud shear connectors at elevated temperatures. Parametric numerical simulations show that when concrete failure wins over stud failure, the height of the connectors, the compressive strength of the concrete, and the level at which concrete temperature is considered, all have a significant impact on the resistance.…”

This is a numerical study to investigate the behavior of novel stiffened angle shear connectors embedded in solid concrete slabs at both ambient and elevated temperatures. An advanced nonlinear finite element model is developed and validated with available experimental work by Nouri, K., et al. 2021. Additionally, parametric studies are performed to evaluate the variations in concrete strength and the connector’s dimensions. The results indicate that the ultimate strength of the stiffened angle shear connector drops by 92% in 1050 °C. Comparing studies show the strength of the stiffened shear connector at 700–850 °C is equivalent to the ordinary C-shaped shear connectors. The stiffened shear connector is more ductile at elevated temperatures as compared to ambient temperatures. The shear strength raised to 66% and 159.7% by increasing the height and width of the stiffened shear connector, respectively. Furthermore, the height of the stiffened shear connector is crucial to enhance the shear strength capacity as compared to the ordinary C-shaped shear connector.
