四川省某砖石古塔隔震加固方案研究
Study on Isolated Reinforcement Scheme of Ancient Masonry Pagoda in Sichuan Province
摘要
Abstract
In order to more effectively protect masonry pagodas and retain their original historical style and features,Pengzhou Zhenguo White Pagoda was examined as a representative case. The isolation performance of the pagoda was analysed using different isolation schemes as parameters. The vertex maximum acceleration,interlayer displacement,and shear force values under rarely severe earthquake before and after isolation were compared,and the wind resistant and anti-overturn status after isolation were calculated. The results showed that the seismic response could be reduced under a rare earthquake by selecting larger isolation bearings and an outer edge arrangement. The maximum acceleration of the vertex was decreased by approximately 80%,while the horizontal shear was decreased by approximately 70%,which effectively improved the seismic safety of the masonry pagoda.关键词
