Experimental and numerical research has been conducted to investigate the role of using angle shear connectors as a replacement of headed stud (HS) on the performance of the composite beams under the effect of the negative bending moment (NBM). The replacement was done by using the same cross-section area for both connectors. A total of five specimens were fabricated and tested under the effect of NBM. Shear connector type, bond interaction (partial and full), and angle shear connectors arrangement were considered as the main parameters. A finite element model (FEM) was built using commercial software for modeling the composite beams. The experimental results, the ultimate strength decreased by 4.12% for single angle shear connectors, compared to the specimens with HS shear connectors. The numerical results showed a good agreement with the experimental results in terms of load-displacement relation and mode of failure.
