چکیده
Abstract This chapter aimed to present different data driven Vibration-Based Methods (VBMs) for Structural Health Monitoring (SHM). family of methods, widely used engineering applications, several advantages damage identification applications. First, VBMs provide continuous information on the health state structure at a global level without need access damaged elements and know their location. Furthermore, can be identified using dynamic response measured by sensors non-necessarily located in proximity any prior knowledge about By principle, identify related changes properties structures, such as stiffness variations due modifications connections between structural elements, or geometric material properties. A classification was presented this chapter. case studies were demonstrate potential these methods.

متن کاملUnsupervised Learning Methods for Vibration-based Damage Detection
The basic premise of vibration-based damage detection is that damage will significantly alter the stiffness, mass, or energy dissipation properties of a system, which, in turn, alter the measured dynamic response of the system. Although the basis for vibration-based damage detection appears intuitive, its actual application poses many significant technical challenges. A fundamental challenge is...
متن کاملPerformance of Vibration-Based Damage Detection Methods in Bridges
The important advances achieved in the modal identification, sensors and structural monitoring of bridges have motivated the bridge engineering community to develop damage detection methods based on vibration monitoring. Some of these methods have already been demonstrated under certain conditions in bridges with deliberate damage (Farrar et al., 1998). However, the performance of these methods...
متن کاملVibration-Based Damage Detection in Wind Turbine Blades using Phase-Based Motion Estimation and Motion Magnification
Vibration-based Structural Health Monitoring (SHM) techniques are among the most common approaches for structural damage identification. The presence of damage in structures may be identified by monitoring the changes in dynamic behavior subject to external loading, and is typically performed by using experimental modal analysis (EMA) or operational modal analysis (OMA). These tools for SHM nor...
متن کاملDamage Detection of Axially Loaded Beam: A Frequency-Based Method
The present study utilizes an analytical method to formulate the three lowest modal frequencies of axially-loaded notched beam through both crack location and load level in a specific format that can be used in existing frequency-based crack-identification methods. The proposed formula provides a basis to shift into two states, one with axial loading and the other without any loading whatsoever...
