Title: Acoustic emission monitoring for assessment of steel bridge details

Abstract

Acoustic emission (AE) testing was deployed on details of two large steel Interstate Highway bridges: one cantilever through-truss and one trapezoidal box girder bridge. Quantitative measurements of activity levels at known and suspected crack locations were made by monitoring AE under normal service loads (e.g., live traffic and wind). AE indications were used to direct application of radiography, resulting in identification of a previously unknown flaw, and to inform selection of a retrofit detail.

  • The monitoring of multiphase flow is an established process that has spanned several decades. This paper demonstrates the use of acoustic emission (AE) technology to investigate sand transport characteristic in three-phase (air-water-sand) flow in a horizontal pipe where the superficial gas velocity (VSG) had a range of between 0.2 ms{sup −1} to 2.0 ms{sup −1} and superficial liquid velocity (VSL) had a range of between 0.2 ms{sup −1} to 1.0 ms{sup −1}. The experimental findings clearly show a correlation exists between AE energy levels, sand concentration, superficial gas velocity (VSG) and superficial liquid velocity (VSL)
  • Delaminations in bridge decks typically result from corrosion of the top mat of reinforcing steel, which leads to a localized separation of the concrete cover from the underlying concrete. Because delaminations cannot be detected using visual inspection, rapid, large-area interrogation methods are desired to characterize bridge decks without disruption to traffic, without the subjectivity inherent in existing methods, and with increased inspector safety. To this end, disposable impactors such as water droplets or ice chips can be dropped using automatic dispensers onto concrete surfaces to excite mechanical vibrations while acoustic responses can be recorded using air-coupled microphones. In this work,more » numerical simulations are used to characterize the flexural response of a model concrete bridge deck subject to both steel and ice impactors, and the results are compared with similar experiments performed in the laboratory on a partially delaminated concrete bridge deck slab. The simulations offer greater understanding of the kinetics of impacts and the responses of materials.« less
  • Acoustic surface waveguides are developed to enhance the transmission of acoustic emission (AE) signals in high attenuating fiber-reinforced plastic (FRP) structures. In this paper, the design of the surface waveguide system and the source location technique are described. Experimental results of using a surface waveguide for AE monitoring of a FRP composite pressure pipe are presented to demonstrate the effectiveness of the proposed waveguide system. A metal wire was selected as a waveguide, and pencil breaks and electronic pulses were used as artificial AE signals. The results indicate that the use of the surface waveguide can significantly increase the AEmore » monitoring range. Also, a high transmission efficiency was experimentally determined for the epoxy joints developed to attach the surface waveguide to the FRP pipe. The proposed surface waveguide appears to be a promising technique for AE monitoring on existing FRP pressure vessels and storage tanks.« less
