摘要
桥梁结构的动力特性是结构抗震、抗风以及进行在线健康监测的基础。介绍桥梁动力特性测试中的脉动测试法以及结果分析中的模态分析法,并结合某斜拉桥的模态试验及结果,分析验证了脉动测试法、模态分析法的有效性,同时为该大桥的进一步研究提供了依据。
The dynamic characteristics of bridge structure are the basis of structural seismic resistance, wind resistance and online health monitoring. The article introduces the pulse test method in the bridge dynamic characteristic test and the modal analysis method in the result analysis. According to the modal analysis and result of a cable-stayed bridge, the article analyzes and validates the effectiveness of pulse test method and modal analysis method, and also provides the basis for the further study of this bridge.
