In this paper, according to the actual engineering application of the case, simulate the structure model to study the steel girder and concrete bearing wall in-plane nodes. The bearing capacity of the node is analyzed considering the axial force of the wall member, the embedded length of the steel beam and the restraining edge member. The influence of the embedded length of steel beam, the concrete strength of concrete bearing wall and the width of flange of steel beam on the bearing capacity of the node of steel beam and concrete load-bearing wall under plane load are studied. By means of large-scale finite element analysis software, The finite element nonlinear simulation analysis is carried out on the wall nodes. By changing the conditions of various factors, several finite element models are analyzed. The maximum load carrying capacity of the joint is analyzed respectively according to the embedded length of steel beam, the concrete strength of bearing wall and the width of the flange of H-beam.
