Through the finite element method and static cohesion method, the shaking table test of the steel structure model was simulated and the simplified analysis model was established. On this basis, the steel structure model with TMD device with high frequency electromagnetic energy was further discussed The comparison and analysis of the natural frequency and the dynamic response of the structure show that the calculated results are in good agreement with the experimental results, which shows that the proposed simplified analytical model and calculation method are reliable.
