DAMAGE ASSESSMENT OF REINFORCED CONCRETE BEAMS USING HILBERT-HUANG TRANSFORM

DAMAGE ASSESSMENT OF REINFORCED CONCRETE BEAMS USING HILBERT-HUANG TRANSFORM

The detection of damage in reinforced concrete bridge using vibration characteristics has been the topic of much research in the last two decades. Since reinforced concrete structures are nonlinear in behaviour, even with relatively low levels of damage, it is difficult to make a reliable estimate on the modal properties for use in the damage detection/health monitoring. The Hilbert-Huang transform (HHT) comprises the empirical mode decomposition (EMP) of the data and performing the Hilbert ...

Detection of Damages in Nonlinear Reinforced Concrete Frames

Detection of Damages in Nonlinear Reinforced Concrete Frames

An objective of the structural health monitoring system is to identify the state of the structure and to detect its damagesafter a major event, such as the earthquake, to ensure the reliability and safety of structures. Innovative analysistechniques for the damage detection of structures have been extensively studied recently. However, practical andeffective damage identification techniques remain to be developed for nonlinear structures, in particular nonlinearhysteretic reinforced concrete ...

A Non-destructive Damage Detection Method for Reinforced Concrete Structures Based on Modal Strain Energy

A Non-destructive Damage Detection Method for Reinforced Concrete Structures Based on Modal Strain Energy

In recent years, much research and development has been carried out on the use of vibration characteristics to detect structural damage in various types of structures. Being a type of the widely developed methods, the vibrations based damage detection methods, in particular modal based methods, are found to be promising in assessing the ldquo;health rdquo; condition of a structure in terms of locating and quantifying damage. However, despite of advances in vibration based damage detection ...
