“…In the last twenty years several approaches have been proposed for damage identification based on the analysis of responses to vibrations recorded on the structures. In references Yan et al, 2007 andFan et al 2011 comprehensive state-of-the-art are reported. A very diffuse approach to the problem of damage detection is based on the analysis of changes of modal characteristics between the original (undamaged) state and the (possibly damaged) current state.…”

“…To 3.3-5 overcome limitations in this assessment process, significant efforts have been made to design remote systems capable of relaying information about scour reducing the need for manual intervention. These systems can be broadly categorized as follows (Prendergast & Gavin 2014): single-use devices (NCHRP 2009;Briaud et al 2011), pulse or radar devices (Forde et al 1999;Yu 2009;Yankielun & Zabilansky 1999), buried or driven rod systems (NCHRP 2009;De Falco & Mele 2002;Zarafshan et al 2012;Fisher et al 2013), sound-wave devices (Nassif et al 2002;Fisher et al 2013;Anderson et al 2007), fiber-Bragg grating devices (Lin et al 2006;May et al 2002) and electrical conductivity devices (Anderson et al 2007). Table 1 gives an overview of the function and detection methodology of a number of types of instrument available.…”

Abstract. When dealing with asset management of infrastructural systems, maintenance planning of bridges and other critical structures has to be thought against natural deterioration due to environmental conditions, but also taking into account potential criticalities induced by the occurrence of seismic and flood hazards. The aim of this work is to focus on potential damage scenarios, assessment methods for common bridge structures potentially subject to earthquake loading and scouring phenomena due to flooding hazards.

“…Traditionally, the performance indicators used for monitoring purposes have been modal-based parameters. Many techniques incorporating modal parameters have been proposed, developed, and expanded upon over the years, several of which are detailed in the following review papers [18][19][20][21][22][23][24][25][26][27][28]. However, the accurate determination of modal parameters from in-service bridges has proven to be quite a non-trivial task that faces numerous challenges and limitations.…”

A State of the Art Review of Modal-Based Damage Detection in Bridges: Development, Challenges, and Solutions

Abstract:Traditionally, damage identification techniques in bridges have focused on monitoring changes to modal-based Damage Sensitive Features (DSFs) due to their direct relationship with structural stiffness and their spatial information content. However, their progression to real-world applications has not been without its challenges and shortcomings, mainly stemming from: (1) environmental and operational variations; (2) inefficient utilization of machine learning algorithms for damage detection; and (3) a general over-reliance on modal-based DSFs alone. The present paper provides an in-depth review of the development of modal-based DSFs and a synopsis of the challenges they face. The paper then sets out to addresses the highlighted challenges in terms of published advancements and alternatives from recent literature.

“…Typical damage identification methods found in the literature are usually developed by processing structural dynamic responses. Such methods can be largely categorized into two groups: vibration-based damage detection methods [5][6][7] and wave-propagation-based damage inspection methods [8][9][10].…”

Hierarchical Wavelet-Aided Neural Intelligent Identification of Structural Damage in Noisy Conditions

A sophisticated hierarchical neural network model for intelligent assessment of structural damage is constructed by the synergetic action of auto-associative neural networks (AANNs) and Levenberg-Marquardt neural networks (LMNNs). With the model, AANNs aided by the wavelet packet transform are firstly employed to extract damage features from measured dynamic responses and LMNNs are then utilized to undertake damage pattern recognition. The synergetic functions endow the model with a unique mechanism of intelligent damage identification in structures. The model is applied for the identification of damage in a three-span continuous bridge, with particular emphasis on noise interference. The results show that the AANNs can produce a low-dimensional space of damage features, from which LMNNs can recognize both the location and the severity of structural damage with great accuracy and strong robustness against noise. The proposed model holds promise for developing viable intelligent damage identification technology for actual engineering structures.
