China's ancient pagoda combines the essence of foreign culture and traditional Chinese architectural art, is an outstanding representative of ancient Chinese high-rise buildings, with valuable cultural relics value.However, it is of great theoretical and practical value to study the seismic response of solid masonry pagoda and to study the seismic response of solid pavement.In this paper, a representative of the solid brick mausoleum tower as an example, designed to produce a 1/8 ratio of Xuan Zang tower model,carried out 7 degrees and 8 degrees ELCENTEO wave of Tianjin wave one-way and two-way vibration table .The experimental results show that the seismic response of the seismic wave is more intense when the seismic wave is bi-directional, and the damage at the top of the Xuanzang tower is more serious due to the seismic wave, which is mainly due to the fact that the tower Layer in the tower structure,indicating that when the structure of the existence of the mutation layer is particularly unfavorable to the earthquake.Using the ABAQUS finite element software, the numerical simulation experiment model of Xuanzang tower was established, and the numerical simulation analysis under the same seismic wave was carried out. The numerical simulation results were compared with the results of the shaking table. The acceleration and displacement of the two were consistent It is shown that the finite element simulation simulation analysis can be used as a supporting method for shaking table test, and can reveal the seismic response and damage site of the ancient tower to a certain extent, which provides practical reference value for the development of the ancient tower.Numerical model of Xuanzhuang pagoda test model structure and the prototype structure establishment, comparison and analysis of the seismic dynamic response of the two. and analyzed the structure of the dynamic similarity relation, verify the rationality of test model. On the basis of seismic response analysis of the damage form of Xuanzhuang pagoda are predicted,reveals the damage law of Guta, to provide reference for the development of Guta protection work.
