【摘要】 中国古建筑以其悠久的历史和丰富的文化内涵,成为华夏文明和世界文明的重要组成部分。由于中国古建筑以木材为主,而木材材质耐久性较差,造成现存古建筑存在不同程度的人为和自然损坏。仿古建筑作为一种新的建筑形式,将现代建筑技术与古建筑艺术二者相结合,为再建、复原古建筑开辟了一条崭新的途径。 九华山回香阁万佛塔建于1782年,20世纪末因人为火灾而毁坏。2001年对其重建,重建采用钢筋混凝土仿古建筑形式,建筑风格参照山西应县木塔进行设计。但由于古建筑体形复杂,为其设计和分析增加了难度。在与山西省古建筑研究所合作的基础上,作者完成了该项目的结构设计和结构分析。 本文是在对古建筑与仿古建筑的研究与应用现状进行调研和对九华山回香阁万佛塔进行全面分析的基础上,结合本工程实际,采用ANSYS软件对万佛塔进行了小震作用下结构的动力分析。动力分析的目的是对结构强度进行计算,控制结构宏观抗震性能。具体分析时,按照以下步骤进行。 1、通过模态分析把握结构的动力特性,找出结构在各个方向的主要振型。更多还原

【Abstract】 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.更多还原
