Bolt end plate connection is one of the most widely used connection methods in steel structures. It is mainly used for beam-column connection and beam-to-beam splicing in a steel frame and a light steel portal steel frame. The connection strength of the bolt end plates of the steel structure under earthquake action reflects the seismic resistance of the steel structure. The analysis method for the bolt end plate connection strength of steel structures under earthquake action is proposed. The finite element model and the model for the bolt end plate strength of the steel structure under earthquake action are established. Under the one-way static load and cyclic load, the connection strength of the bolt end plate connection joints is simulated and analyzed. The analysis results show that under the action of earthquake, the thickness of the bolt end plate has little influence on the contact area, but it has a great influence on the contact stress. Under the action of earthquake, when the column web and the beam are yielded at the same time, the envelope is the fullest, the energy dissipation coefficient is also the largest, and the seismic performance is the best. The analytical results of the tested methods are in good agreement with the actual values, and the correlation coefficient is always greater than 0.99.
