| 中文摘要: |
| 虽然结构声强技术已成功地应用于匀质薄壁结构，但在建筑结构的应用研究只是一些定性的探讨，本文应用结构声强技术研究建筑结构中弯曲波声强的测量，以传统方法获得的结构总损耗能量测量值为参考、基于95％合成置信区间研究弯曲波声强的测量精度，初步探讨结构声强技术在建筑中应用的可行性． |
| 英文摘要: |
| Although structural intensity techniqes have been successfully applied to uniform thin structures, its applications to building structures are only in qualitative studies.In this paper the measurements of structural intensity in building structures are carried out and the measurement accuracy is studied based on the 95% combined confidence interval of the intensity and the total energy dissipated in the structure. It studies the feasibility of the applications of structural intensity techniques to building structures. |
