“…Since the crack in this period is much larger than the previous step from 1100 to 2100, the propagating stress wave attenuates more than the previous period. The cycles (6)(7)(8)(9)(10)(11) shown in the damage index are more clear than the previous cycles (1)(2)(3)(4)(5). In addition, the highest values of the damage index reached to one, which implies the concrete column was subject to severe damage in the maximum displacement of each cycle.…”

“…In this project, piezoceramic-based devices, called smart aggregates (SA), were utilized as transducers for structural health monitoring of RC columns under a pseudo-dynamic loading procedure. In addition to the structural health monitoring function, the smart aggregate can be used to perform early-age concrete strength monitoring [8,9], impact detection [10], seismic detection [11], and soil freeze-thaw monitoring [12], demonstrating that SAs are multi-functional devices. In previous studies, SAs have been successfully implemented for structural health monitoring of various concrete structures under different loading cases including: a concrete bridge bent-cap under static loading [13], a concrete frame under static loading [14,15], a shear wall under reversed cyclic loading [16], columns under seismic loading [17], stress wave base communication in concrete structures [18,19] and columns under reversed cyclic loading [20,21].…”

Structural health monitoring is an important aspect of maintenance for bridge columns in areas of high seismic activity. In this project, recently developed piezoceramic-based transducers, known as smart aggregates (SA), were utilized to perform structural health monitoring of a reinforced concrete (RC) bridge column subjected to pseudo-dynamic loading. The SA-based approach has been previously verified for static and dynamic loading but never for pseudo-dynamic loading. Based on the developed SAs, an active-sensing approach was developed to perform real-time health status evaluation of the RC column during the loading procedure. The existence of cracks attenuated the stress wave transmission energy during the loading procedure and reduced the amplitudes of the signal received by SA sensors. To detect the crack evolution and evaluate the damage severity, a wavelet packet-based structural damage index was developed. Experimental results verified the effectiveness of the SAs in structural health monitoring of the RC column under pseudo-dynamic loading. In addition to monitoring the general severity of the damage, the local structural damage indices show potential to report the cyclic crack open-close phenomenon subjected to the pseudo-dynamic loading.

The piezoelectric ceramics sensors are embedded in the concrete columns with large and small eccentric compression for crack online monitoring. The digital oscilloscope receiver is applied to obtain in real-time the full waveform characteristics of acoustic emission signal during the column damage process. Using signal processing and passive monitoring technology, this article conducts crack development of real-time dynamic monitoring and evaluation on the damage process of the two specimens by the piezoelectric sensors. The experiment results show that the generation and development of the cracks are obviously companying with the acoustic emission phenomena. The energy accumulation process of the acoustic emission signal has obvious deference from the two specimens and shows basically the property of the cracks development. This technology opens a new road for real-time monitoring and damage detection on line for cracks of concrete structures.

“…In the context of overheight vehicle detection, piezoelectric sensors depend on the force of impact with a vehicle to generate an electrical response that can be used to trigger any of a variety of warning and signaling devices to an overheight condition (Song et al, 2007). In this regards, piezoelectric sensors are not completely preventive.…”

IntroductionOverheight vehicle impacts with bridges are surprisingly common and are of particular concern in areas of Indiana such as the I-65 -I-70 merger location in Indianapolis. The damage from collisions can range from minor to severe, and there is evidence that some bridges are impacted multiple times, leading to the potential for cumulative damage effects. With this in mind, there is a clear need to attempt to prevent overheight vehicle collisions with bridges; and this study provides an in-depth examination of the availability and in-field performance of Overheight Vehicle Detection and Warning (OVD&W) systems that could help address this challenge. FindingsThe findings of this study indicate that most states have updated their infrastructure to account for overheight vehicles and permanently avoid collisions. The few states that still actively employ overheight vehicle detection and warning systems (OVD&W) tend to use optoelectronic single-or dual-eye infrared detection systems and report that the devices have decreased the amount of damage occurring to their structures. The initial equipment and installation costs of these systems range from a few thousand to twenty-five thousand dollars based on DOT interviews, and on-going maintenance appears minimal. Overall, considering that the only other completely effective option to avoid overheight vehicle incidents is to raise the height of affected structures, or lower the roadway surface, an (optoelectronic) OVD&W system is a relatively inexpensive and effective method for decreasing overheight vehicle accident. ImplementationThe combined insights gained through this study were used to develop a straight-forward decision tool that can be employed by INDOT personnel to identify equipment options to address site specific needs for overheight vehicle protection. This tool and its underlying principles were applied to a test case focused on the I-65 -I-70 merger location in Indianapolis, IN leading to a preliminary OVD&W system strategy for that specific location. It is recommended that the sensor characteristics and design decision logic exemplified through this case example be used for future OVD&W system deployment envisioned in the State. AbstractOverheight vehicle impacts with bridges are surprisingly common. The damage from collisions can range from minor to severe, and there is also evidence that some bridges are impacted multiple times, leading to the potential for cumulative damage effects. Thus there is a clear need to attempt to prevent overheight vehicle collisions with bridges.This Synthesis Study provides a review of solutions that exist to detect and forewarn overheight vehicles and thereby prevent a collision, and specifically examines the breadth of available overheight vehicle detection technologies, the commercial availability of such equipment, and the experience of relevant DOTs with installed and functioning systems.The findings of this study indicate that most states have updated their infrastructure to account for overheight vehicles an...
