“…While many methods can be employed for the identification of damage in structures, the success of these methods are limited to cases where damage is severe enough to result in significant changes in the global modes of response of the structural system (Doebling et al 1996). Most recently, researchers have explored the use of high-frequency local response measurements of structural components to identify the onset of damage (Park et al 2000). As a result, the success of these techniques will necessitate accelerometers that exhibit superior performance in the high frequency bands of interest.…”

Abstract:The use of advanced embedded system technologies such as microelectromechanical system (MEMS) sensors and wireless communications hold great promise for measuring the response of civil structures to ambient and external disturbances. In this paper, the design of a high-performance planar piezoresistive MEMS accelerometer is discussed in detail. The piezoresistive accelerometer possesses superior performance characteristics including low noise densities when measuring local structural responses characterized by high-frequency content. A low-cost wireless sensing unit, designed for automated structural monitoring, is utilized to record and wirelessly transmit measurements obtained by the piezoresistive accelerometer. To validate the performance of the wireless monitoring system including the interfaced piezoresistive accelerometer, a five degree-offreedom laboratory test structure is utilized. Introduction:The field of structural engineering can gain great benefit by embracing new technologies being developed in related fields such as microelectromechanical system (MEMS) sensors and wireless communications. One area where advanced technology can have an immediate impact is in improving the current state-of-practice of structural monitoring systems. The importance of structural monitoring is growing due to the recognition that monitoring is an effective vehicle for advancing our understanding of civil structures and their response to external loads. For example, research directed towards developing performance-based earthquake engineering design criteria can benefit from wide-spread use of monitoring systems because they provide empirical data for validation of structural and statistical models. Structural monitoring systems are also required for the acquisition of real-time response time-histories that are used by structural health monitoring algorithms to rapidly identify potential damages in a structural system.

“…By comparing the impedance signature taken in the pristine state and at any other time, structural damage can be determined. Generally, both frequency and amplitude shifts are produced relative to the pristine state (without damage) (Ayres et al, 1998;Chaudhry et al, 1995;Sun et al, 1995;Park et al, 2000;Zagrai and Giurgiutiu, 2001;Giurgiutiu et al, 2002Giurgiutiu et al, , 2004Peairs et al, 2004;Narayanan and Subramaniam, 2016a). Application of EMI technique for damage detection in concrete structures requires a careful study of the changing compliance of the substrate for different forms of damage in the substrate material from the incipient to the visible stages.…”

“…Application of EMI technique for damage detection in concrete structures requires a careful study of the changing compliance of the substrate for different forms of damage in the substrate material from the incipient to the visible stages. The use of PZTs for health monitoring of concrete structure was demonstrated by the ability of EMI technique to register changes due to formation of cracks well in advance of failure (Park et al, 2000;Narayanan and Subramaniam, 2016b). Several other studies of damage in concrete using impedance-based measurements of PZTs have been conducted using embedded defects and artificial damage in the form of machine cuts (Tseng and Wang, 2004;Lim et al, 2006;Dongyu et al,2010;Wang et al, 2013).…”

Piezoelectric based PZT (Lead Zirconate Titanate) smart sensors offer significant potential for continuously monitoring the development and progression of internal damage in concrete structures. Changes in the resonant behavior in the measured electrical conductance obtained from electromechanical (EM) response of a PZT bonded to a concrete substrate is investigated for increasing levels of damage. Changes in the conductance resonant signature from EM conductance measurements are detected before visible signs of cracking. The root mean square deviation of the conductance signature at resonant peaks is shown to accurately reflect the level of damage in the substrate. The findings presented here provide a basis for developing a sensing methodology using PZT patches for continuous monitoring of concrete structures.

“…However, in recent years, there has been a renewed interest in formulating new approaches to damage detection that are more robust in the face of environmental factors. In particular, new damage detection methods receiving recent attention all include the use of new analytical tools such as pattern recognition (Sohn and Farrar 2001), Bayesian system identification (Yuen, Au and Beck 2004) and active sensing impedance spectroscopy (Park, Cudney and Inman 2000). To validate and compare the performance of current and future damage detection methodologies, a powerful structural health monitoring benchmark study has been devised that offers an extensive data set collected from a full-scale laboratory structure tested under ambient and forced vibrations.…”

In this paper, a novel approach to the characterization of structural damage in civil structures is presented. Structural damage often results in subtle changes to structural stiffness and damping properties that are manifested by changes in the location of transfer function characteristic equation roots (poles) upon the complex plane. Using structural response time-history data collected from an instrumented structure, transfer function poles can be estimated using traditional system identification methods. Comparing the location of poles corresponding to the structure in an unknown structural state to those of the undamaged structure, damage can be accurately identified. The IASC-ASCE structural health monitoring benchmark structure is used in this study to illustrate the merits of the transfer function pole migration approach to damage detection in civil structures.
