One drawback to this technique is the need to access both sides of the member of interest.
The surface of the concrete was smoothened and cleaned before the mounting, and the rebars were detected using a profometer to avoid installing the sensors directly underneath the rebars.

Figure shows how AE features vary during concrete cracking. Thus, this study focused on assessing the additional required number of tendons for different AASHTO I-girder types and spacing between them to achieve the redundancy of I-girder bridges.
The lower values of the energy calculated when trucks were crossing the road-viaduct can, therefore, be due to low values of duration. When restoring or renovating an old timber structure, or when adapting it to a new use, it is often necessary to evaluate the structural integrity and load-carrying capacity of the timbers.
Grid 2 comprises Channels 2, 9, 10, 13, 18, 23 to evaluate the condition of the connection slab-girder.

To properly locate the damaged areas in the structure, an understanding of the places where rot is likely to occur is essential.
There may be deterioration present within the core of a timber that cannot be seen and is too deep to probe with an awl.
In-place evaluation of wood-based materials and metals• These events contain a transient and a following oscillation, and they are preceded and followed by intervals of quiescence and ambient vibrations.
Moreover, the speed of light vehicles is generally higher than the one for trucks, which can generate hits containing more than one AE event, which gives higher values of duration.
State-of-the-art information on visual inspections, destructive and nondestructive testing NDT , and the hands-on experience provided in this seminar, are essential for those involved in evaluating concrete, masonry, wood, and metal structures.
One of the significant issues related to structural health monitoring is how to accurately interpret monitoring data in order to provide reliable condition assessment results.
Moreover, given that the design value is based on the 5 th percentile exclusion limit, flexural stresses that are more than 100 psi above the design value might reasonably be considered acceptable for timbers in existing structures, particularly if the timbers are performing well.
