In this study, the behavior of cold formed steel portal frame apex connection subjected to major axis bending moments have been investigated. For this purpose, experimental and numerical models have been developed. Two types of fasteners have been studied. First, self-drilling screws with diameter 6mm, whereas the second type is ordinary bolts of diameter 12mm. Four specimens have been fabricated to investigate the behavior of these connections. Further, the specimens are modeled numerically using (ABAQUS) software. The model is verified by comparing its results with the experimental tests. A parametric study was conducted to investigate the effect of bolt type, gusset plate thickness, bolt number and arrangement, and the use of lower flange plate
