【摘要】 结构动力特性是由结构自身固有的质量和刚度决定的,因此可以用来评价古建筑结构的抗震性能和损伤状态。基于可园邀山阁保护技术的研究,介绍了应用环境随机激振技术测试砖结构古建筑动力特性的要点和方案,并将测试结果与有限元分析软件ANSYS计算分析的结果进行了对比,获得的试验结果较为理想,说明建立的可园邀山阁有限元模型是可靠的,采用的测试方法是合理、可行的。这些将为同类古建筑的测试、抗震评估及维修加固提供有益的参考。更多还原

【Abstract】 The Structural dynamic behavior of structure is determined by the inherent quality and stiffness of the structure,thus it can be used to evaluate the seismic property and structure damage of historic building structure.On the base of the research of protection technology on Yaoshange in Ke Garden,the key points and schemes for applied ambient random excitation technology to determine the dynamic behavior of ancient masonry building is introduced.The test scheme for Yaoshange is verified by the results of finite element software ANSYS.The test results obtained are ideal.The results show that finite element model of Yaoshange in Ke Garden is reliable and the test method is feasible.It will provide a useful reference for similar ancient buildings in test of dynamic behavior,seismic performance evaluation,repair and reinforcement.更多还原
