Mechanically fastened FRP systems
"Rehabilitation of existing structures with Fiber Reinforced Polymers ( RP) has been growing in popularity because of their superior performance in terms of resistance to corrosion and high stiffness-to-weight ratio. Of the several external strengthening systems that have proved to be effective and efficient, Mechanically-Fastened (MF) FRP pre-cured laminates are now emerging as a promising technique which, in some cases, presents substantial advantages with respect to bond systems.
The purpose of this research was to validate, from a mechanics point of view, the Mechanically-Fastened Fiber Reinforced Polymer (MF-FRP) as a rapid and efficient strengthening system to retrofit existing deteriorated reinforced concrete badges.
Tensile tests, in the longitudinal and transverse direction of the laminate, were performed on full section and open hole coupons in order to characterize the material. Bearing tests, in the longitudinal and transverse direction of the laminate, were done to find the capacity of the fastener-FRP-concrete connection. Finally, shear-bond tests were conducted using different bolts and varying boundary conditions such as the presence of washer, epoxy and clamping torque. The results of the experimental tests were analyzed to assess the complete load-deformation behavior, the efficacy of the strengthening method and its configuration.
In addition, three structurally deficient badges were strengthened using MF-FRP during the period of January-May 2004 and load tested in order to have a feedback on the design assumptions"--Abstract, page iii.
