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 کاملAnalysis of Concrete Bridge Girders Strengthened with Frp Laminates under Service and Extreme Loading Conditions
The project is a continuation from fiscal year 2004-2005. Previous work aimed at developing new analytical tools for analysis of RC beams strengthened with FRP laminates. The models were used to analyze several test specimens of RC beams and to investigate the corresponding failure mode, and whether it is due to CFRP fracture, debonding, or concrete crushing. Current work focused on using the e...
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 کاملUniversality of the Frequency Spectrum of Laminates
Waves in periodic media undergo multiple scattering and interference. As a result, their frequency spectrum is divided into bands in which waves pass freely, and gaps in which waves cannot propagate. This band diagram depends on the physical and geometrical properties of the periodic cell, through a dispersion relation. Using a new representation of the dispersion relation of laminates, we show...
