Sensitivity Analysis of Transmissibility Functions for Structural Damage Detection
In order to assess structural safety conditions, many vibration-based damage detection methods have been developed in recent years. Among these methods, transmissibility function analysis can utilize output data only, and proves to be effective in damage detection. However, previous research mostly focused on experimental validation of using transmissibility function for damage detection. Very ...
متن کاملOutput-Based Structural Damage Detection by Using Correlation Analysis Together with Transmissibility
Output-based structural damage detection is becoming increasingly appealing due to its potential in real engineering applications without any restriction regarding excitation measurements. A new transmissibility-based damage detection approach is presented in this study by combining transmissibility with correlation analysis in order to strengthen its performance in discriminating damaged from ...
متن کاملDamage detection of metro tunnel structure through transmissibility function and cross correlation analysis using local excitation and measurement
In a modern metropolis, metro rail systems have become a dominant mode for mass transportation. The structural health of a metro tunnel is closely related to public safety. Many vibration-based techniques for detecting and locating structural damage have been developed in the past several decades. However, most damage detection techniques and validation tests are focused on bridge and building ...

Copyright Notice iv To my parents and to my wife Yang and my daughter Grace for their love, support, encouragement, and inspiration v Acknowledgements I would never have been able to finish my dissertation, reach the heights or explore the breadths of knowledge without the guidance of my committee members, the discussions with my collaborators and colleagues, the support from my family and my w...
متن کاملDamage Detection in Beam-like Structures using Finite Volume Method
In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...
