Abstract:
In order to study the influence of mountainous topography on the seismic response of the ancient masonry pagoda,we took the Zhongjiang South Pagoda located on top of the Tongyu Mountain in Zhongjiang County,Sichuan Province as a prototype,and selected the acceleration recordings by the stations of the Zigong Array during the Wenchuan MS8.0 earthquake as the input,and studied through a small shaking table test the variation trend of the natural vibration frequency of the structure at the bottom and on top of the mountain with the amplitude of input ground motion.We further analyzed the influence of the topographic effect on the seismic response of the ancient pagoda and the failure mode of the pagoda.The results show that the natural frequency of the ancient pagoda remains unchanged under the action of low-amplitude ground motion,and when the peak of free surface ground motion reaches 100 Gal and 150 Gal respectively,the ancient pagodas on top and at the bottom of the mountain is damaged.Under the influence of the natural vibration characteristics of the ancient pagoda,the spectral characteristics of the input ground motion and the building constitution,the ancient pagoda has undergone a failure mode of “slight on top and severe at the bottom” .The peak acceleration,maximum relative displacement and maximum inter-story drift of each floor of the ancient pagoda at the top of the mountain are 2-3 times,1.5-4.5 times and 1.5-4.5 times of those at the bottom of the mountain under the same working conditions,and the amplification factor of maximum relative displacement and maximum inter-story drift is related to the amplitude of input seismic motion.Thus,it is necessary to pay attention to the seismic safety of the ancient pagoda on the mountain.
