In this thesis, the influence of column force, joint hoop reinforcement, and repeat load on the stress and sheer bearing capability of inclined pressure bar is analyzed utilizing finite element software. In the case study, the column axial force's influence on the inclined pressure bar's equivalent width, stress and sheer bearing capability of RCFEN is obtained by changing the column force when modeling the RCFEN with ANSYS. In the former model, the joint hoop reinforcement influence on the equivalent width inclined pressure bar and the strength of RCFEN is achieved by changing the quantity of joint hoop reinforcement; the inclined pressure bar's equivalent width and the strength variation of RCFEN under cyclic load are gained by applying low frequency cyclic load on the inflection point of column and the middle of beam.
