Structure Dynamic Analysis Of Jiuhua Mountain Huixiang Pavilion Ten Thousand Buddha Tower

Chinese ancient building becomes an important part of cathaysia and world civilization as its time-honored history and rich in culture. Since ancient building were built mainly by wood and the durability of the wood is little better in china, these do different extent artificial and nature damage to existing ancient building. The reproduction of ancient building as a new architecture form combines modern building technology with ancient building art. It establishes a new path for rebuilding and restoring ancient building.The tower was built in 1782 and destroyed by fire in the end of 20 century .In 2001 it was rebuilt. The reconstruction of the tower was adopted by the reproduction building form of reinforced concrete. Its style refers as the wood tower of YingXian in shan xi province. On the basis of the cooperation with ancient architecture institute in shan xi province, the author finished its structural design and analysis.On the basis that the research and application of existing state has been investigated and the tower has been fully analyzed, the author adopted ANSYS to analyze dynamically. The purpose of dynamic analysis is to calculate its structural strength and manipulate quake-proof performances of macro structure. Specific analysis is as follows:1 Through modal analysis, we can grasp structural dynamic characteristics and find out structural main mode at each direction.2 By utilizing the acceleration response spectrum analysis, we can find out maximum internal force and the most main design factors of each structural element to provide some references for its structural design. By means of analyzing the nodal stress of floors lab beam and column element, we can further find out the weak position of the structure.3 By utilizing ANSYS ,the structure has been analyzed dynamically. According to the sort of the building site, the author proceed respectively the checking calculation by adopting three acceleration time-history curves of EI Centro Tang Shan and Ren Gong in order to prevent the minor structural element form destroying. According to the results of the structural analysis, the structural design of the tower has been improved.The experience proves that the combination of structural analytic soft of ANSYS and structural design soft of PKPM is of importance to the reliable design of irregular and complex structure.The analytic results of the paper offer meaningful reference to the similar structural design in the future.
