基于振动的方法是评估桥梁结构性能的有力工具。在本文中，插值损伤检测方法是用来解释的频率响应函数（FRF）的测量进行钢筋混凝土单跨桥梁的集中损伤水平的增加。该方法的灵敏度记录和讨论的实验数据的量和损害的严重程度。结果令人鼓舞。它们显示了该方法在大多数考虑的情况下正确检测损坏位置的能力，并给出损坏的相对严重程度的定量指示。并与模态曲率法的计算结果进行了比较。(C)2014爱思唯尔有限公司版权所有。
Vibration based methods are powerful tools to assess the structural behavior of a bridge. In this paper, the Interpolation Damage Detection Method is used to give an interpretation of frequency response function (FRF) measurements performed on a reinforced concrete single span bridge subject to increasing levels of concentrated damage. The sensitivity of the method is documented and discussed with respect to the amount of experimental data available and the severity of the damage. The results are encouraging. They show the ability of the method to correctly detect the damage location in the majority of the scenarios considered and to give quantitative indication of the relative severity of the damage. A comparison with the results obtained by the Modal Curvature Method is also presented. (C) 2014 Elsevier Ltd. All rights reserved.
