Abstract | Most structures are built to have a long life. However, during this long life, they can be incurred damage due to structural deterioration, environmental effects and random actions such as impacts. Early damage assessment and appropriate retrofitting will enable the continued safe and efficient functions of the structures. In this context, vibration based techniques have emerged with the potential for reliable damage assessment. This study develops a dual criteria approach based on the vibration characteristics for detecting and locating damage in arch bridges. Steel arch bridges are one of the aesthetically pleasing bridge types in which damage has been rarely studied. In particular, the arch rib and struts (or columns in deck type bridges) which are important structural components, have received much less attention in damage detection. This study will therefore focus on damage detection in arch bridge structural components using indices based on modified Modal Flexibility (MF) and Modal Strain Energy (MSE) methods. The study is carried out through numerical simulations supported by limited experimental testing. The modelling techniques are first validated through experimental testing of a laboratory scale arch bridge model and this is followed by damage detection studies in this bridge structure. Data obtained from finite element analyses of the healthy and damaged arch bridge models are applied into the modified MF and MSE algorithms for detecting and locating the damage. Results demonstrate that the proposed method is capable of detecting damage in the arch rib and vertical columns of deck type arch bridges. |
