  3. Acoustic Emission Monitoring for Assessment of Steel Bridge Details

    6108vb26w?file=thumbnail
    Description: 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...

  4. White Paper: Tiltmeter-Based Bridge Scour Monitoring

    Fj236210v?file=thumbnail
    Description: Scour is by far the primary cause of bridge failures in the United States. Scour and other hydraulic effects are particularly threatening because the deterioration is often invisible, hidden beneath turbid water. Many scour monitoring methods attempt to measure the development of scour pockets themselves. However, this is difficult due...

  6. Localization of Noise Sources in Large Structures Using AE

    Pr76f3467?file=thumbnail
    Description: This paper describes application of AE monitoring techniques to localize the sources of large noises in civil structures. These noises occur during operation of moveable portions of a structure in such things as lift bridges and moveable sports stadium roofs. The use of straightforward AE monitoring techniques can provide clear...

  9. Crack Response to Blast Vibrations and Moisture Induced Volumetric Changes in Foundation Soils

    Work
    Description: In this paper vibratory crack response is compared to that produced by volumetric changes in foundation soils induced by natural events. These natural phenomena include changes in the water table, changes in soil moisture, and formation of ice lenses to name a few. Previous papers have compared vibratory responses of...
