摘要

古塔的动力特性是评价其结构抗震性能和损伤状态的重要指标。本文介绍了秦峰塔动力特性测试的方法、过程及测试结果。为了得到秦峰塔准确的结构动力特性

为古塔的维修及保护提供依据

采用环境激励的方法测试了秦峰塔的动力特性

得到了其前三阶固有频率、振型和阻尼比;然后采用有限元软件ANSYS对秦峰塔建立有限元模型

并进行模态分析。所得计算结果与测试结果相比

误差较小

说明所建立的有限元模型是可靠的

可以为古塔的后续动力响应分析提供理论分析模型

测试结果可供同类古塔的维修加固、抗震鉴定等参考。

Abstract

The dynamic characteristic is an important index to evaluate the anti-seismic property and damage state of ancient pagodas.The experiment method

process and measurement results were introduced in this paper.In order to obtain the dynamic characteristics of Qinfeng pagoda for the purpose of preservation and repair

the dynamic measurements were carried out by ambient excitation and the three frequencies

mode shapes and damp ratios were obtained.Then

the finite element（FE） model for Qinfeng pagoda was developed based on the test documents and modal analysis is made using the developed FE model.It can be concluded that the results of dynamical characteristic calculated by the FE model are accordance with those measured from the field test.The results from the experiment can provide the reference for the maintenance

reinforcement and earthquake-resistance of similar ancient pagodas.
