This paper compares the results of a nonlinear finite element analysis (FEA) of an internal hybrid steel beam to RC column connections with those of the experiment on a half-scale. This study used extended face bearing plates (EFBP) embedded in the panel zone (PZ) to make prefabricated RC column to steel beam connections (PRCS). Steel beam flanges were made to be stronger than scaled sections to transfer more force to the PZ. Nonlinear FEA was performed with ABAQUS software to evaluate the connections under unidirectional loading. Failure mode, connection stiffness, and PZ shear strength determined by nonlinear FEA matched well with the experimental findings. PRCS1 model was used to evaluate the number of PZ stirrups, axial load on the column, width and height of EFBP, and height of stiffener connected to the beam flange. PZ shear strength and stiffness were significantly improved by increasing EFBP width. Increasing the height of EFBP only with increasing the height of the stiffener can increase the shear strength of the PZ. Increasing the axial load of the column had a significant effect on increasing the shear strength of the PZ. PZ shear strength of the PRCS4 with cover plates (CP) was also assessed by developing its numerical model and strengthening the beams and columns. The presence of CP in the sample without a steel web panel (SWP) illustrated a significant effect compared to the sample with SWP. Based on the performance of the CP in different PZ forms, the formulation was developed to determine the shear strength of CP.
