Abstract: Recent world events have exposed the vulnerability of civilian infrastructure under the extreme effects of accidental or man-made explosions with respect to protecting the lives and safety of occupants. Accordingly, there exists a need to develop new retrofit strategies to mitigate the effects that explosions have on structures. To date, a great deal of research has focused on the
use of fibre reinforced polymer (FRP) materials for the retrofit of seismically deficient structures and structures suffering from corrosion related problems. Recently, research has begun focusing
on the application of FRP retrofits for blast resistant structures. The advantages of FRP – including adaptability and high strength-to-weight ratio – offer tremendous potential for retrofitting existing structures against potential blasts threats. However, FRP retrofitted structures subjected to impulsive loading are susceptible to premature failure caused by FRP debonding. Consequently, the Blast Research Group at the University of Ottawa is actively investigating the innovative use of FRP anchors to increase the blast capacity of FRP retrofitted reinforced concrete structures.
