dc.description.abstract
The use of fiber-reinforced polymers (FRP) in civil construction applications with the
near-surface mounted (NSM) method has gained considerable popularity worldwide and can
produce confident strengthening and repairing systems for existing concrete structures. By using this
technique, the FRP reinforcement is installed into slits cut into the concrete cover using cement mortar
or epoxy as bonding materials, yielding an attractive method to strengthen concrete structures as an
advantageous alternative to the external bonding of FRP sheets. However, in addition to the two
conventional failure modes of concrete beams, sudden and brittle debonding failures are still likely to
happen. Due to this, a damage identification technology able to identify anomalies at early stages is
needed. In this work, some relevant cluster-based methods and their adaptation to electromechanical
impedance (EMI)-based damage detection in NSM-FRP strengthened structures are developed and
validated with experimental tests. The performance of the proposed clustering approaches and
their evaluation in comparison with the experimental observations have shown a strong potential of
these techniques as damage identification methodology in an especially complex problem such as
NSM-FRP strengthened concrete structures
