摘要
本研究旨在通过全尺寸环境振动试验与有限元分析相结合的方法，研究泰国清迈素贴寺(Phrathat Doi Suthep temple)一座备受尊敬的砖砌体倒钟形佛塔的基本动力特性。研究结果表明，有限元分析表明，x、y和扭转方向一阶振型的固有频率分别为3.817 Hz、3.836 Hz和9.294 Hz。从环境振动测量中，频率分别为4.086 Hz、4.025 Hz和10.819 Hz。通过比较，有限元计算得到的频率值与实测值相近。差额分别为6.59%、4.70%和14.09%。因此，本文对有限元模型进行了验证，并将其用于所附论文(砖砌体倒钟形车体的抗震性能)中的振动分析。
Ambient Vibration Tests and Finite Element Analysis for Dynamic Properties of Brick Masonry Inverted Bell-shaped Chedi
This research is aimed to study fundamental dynamic properties of an esteemed brick masonry inverted bell-shaped chedi at Phrathat Doi Suthep temple, Chiangmai, Thailand, by using full-scale ambient vibration tests associated with the finite element analysis. The study results showed that the finite element analysis indicated 3.817 Hz, 3.836 Hz and 9.294 Hz for the natural frequencies of the first modes on the x, y and torsion directions. From the ambient vibration measurements, the frequencies were 4.086 Hz, 4.025 Hz and 10.819 Hz. In comparison, the finite element gives the similar frequency values with the measured ones. The discrepancies are respectively 6.59, 4.70 and 14.09 percent. Hence, the validation of the finite element model has been made and used for vibration analysis presented in the accompanied paper (Seismic Performances of Brick Masonry Inverted Bell-Shaped Chedi)
