Bond of Frp Laminates to Concrete
Fiber reinforced polymer (FRP) laminates are being successfully used for strengthening of existing reinforced concrete structures. Bond of the FRP reinforcement to the concrete substrate is of critical importance for the effectiveness of the technique. In this project, flexural test specimens were prepared to address some of the factors expected to affect bond, namely, bonded length, concrete s...
متن کاملField Assessment of Urm Walls Strengthened with Frp Laminates
Unreinforced masonry (URM) walls strengthened with composites were tested to failure at a decommissioned building in St. Louis, Missouri. The walls were subjected to out-of-plane loading. Previous work on URM as well as reinforced masonry walls strengthened with FRP laminates has shown remarkable increases in capacity and ductility. However, most of this research work has been conducted in the ...
متن کاملLap Splice Length and Fatigue Performance of Frp Laminates
In this paper, the lap splice length and the long-term (fatigue) performance of lap-spliced carbon FRP laminates were investigated. Lap-spliced CFRP coupon specimens were fabricated with a splice length of 12.7, 25.4, 38.1, 50.8, 76.2, and 101.6 mm. To eliminate the bending on the lap splice joint, a symmetric specimen configuration was adopted. The width of the specimens was 38.1 mm. These spe...
متن کاملAnalysis and design of pultruded FRP shapes under bending
A comprehensive approach for the analysis and design of pultruded FRP beams in bending is presented. It is shown that the material architecture of pultruded FRP shapes can be efficiently modeled as a layered system. Based on the information provided by the material producers, a detailed procedure is preserited for the computation of fiber volume fraction (V r) of the constituents, including fib...
متن کاملThe optimum configuration of FRP laminates of coupling shear wall concerning the load capacity
Using of CFRP carbon sheets because of their high strength, lightness and ease of use have been very expanded in retrofitting concrete members. Including shear walls systems FRP can be used in order to rebuild or maintain the strength of an aged structural member. Repairing, or retrofitting of the intact structural member is conducted to enhance the structural resistance that was deteriorated d...
