In order to better study the impact of near-field vibration pulse effects on high-rise structures, a random point source method and an equivalent velocity pulse superposition method were used to generate 26 multi-environmental near-field vibration samples with pulse effects for 7-degree fortification. Through the finite element modeling and analysis, the vibration type of the light and heat tower structure is obtained, and the seismic response of the heat absorption tower is analyzed by the generated random ground motion, and the mean value and variance of the structure dynamic amplification factor, base shear force and displacement angle are obtained. Coefficient of variation. The results show that the random seismic response of the structure shows an obvious discrete type, the dispersion of the acceleration amplification factor increases with the height of the tower, the displacement response increases with the height of the tower, and the steel structure on the top of the tower has a significant whiplash effect.
