摘要
介绍了线性多自由度体系在随机分布荷载作用下产生反应的功率谱密度函数和自相关函数,基于上述理论介绍了桥梁结构的动力荷载试验的基本原理、试验项目、试验目的.结合工程实例,阐明了桥梁结构的动力荷载试验在桥梁检测评估中的应用.
The power spectral density function and autocorrelation function of linear MDOF structure under the random loading is presented in the paper. Based on the principle, the test purpose, the test items are introduced. Combining with the project, the paper illuminates the use of the bridge dynamic load test in the bridge test and evaluation.
