Fire Resistance Testing of Concrete Slabs Reinforced by GFRP Rebars

Journal of Applied Fire Science, 2005
This article investigates experimental testing of fire resistance of concrete beams reinforced by GFRP rebars. Three beam specimens were used in the fire exposure testing with emphasis on their ability to sustain loads under fire exposure. One specimen was reinforced with ordinary steel rebars and the other two specimens were reinforced with GFRP ...

Design Recommendations for Bond of GFRP Rebars to Concrete

Journal of Structural Engineering, 1996
To develop design guidelines for bond of glass-fiber-reinforced plastic (GFRP) rebars to concrete, a total of 102 specimens were constructed and tested subjected to monotonic static loading. The research program was inclusive of the experimental testing of 48 beam specimens, 18 pull-out specimens, and 36 hooked rebar specimens.

Study on Stress Relaxation Properties of GFRP Rebars/Bolts

Advanced Materials Research, 2010
Glass fiber reinforced plastics (GFRP) rebars / bolts are more and more being applied in construction projects with its superior corrosion resistance. To improve the economical efficiency of their application it is very significant to develop the prestressed GFRP rebars/bolts structure system.

Development Length of GFRP Rebars Based on Pullout Test

Journal of the Korea Concrete Institute, 2007
The development length equations of the GFRP rebars are suggested based on the pullout tests performed in this study. A total of 48 pullout and modified pullout tests were completed. Test variables included embedment length (L=10, 15, 20, and ), vertical and horizontal installation of the rebars, height of the rebars (H=100 and 300 mm), and cover ...

Bond strength improvement of GFRP rebars with different rib geometries

Journal of Zhejiang University-SCIENCE A, 2007
Based on the Canadian Standards Association (CSA) criteria, 105 pullout specimens were tested to investigate the effect of different rib geometries on bond strength of glass fiber reinforced polymer (GFRP) rebars embedded in concrete. Two kinds of conventional reinforcing rebars were also studied for comparison.

High temperature effects on concrete members reinforced with GFRP rebars

Composites Part B: Engineering, 2013
Abstract GFRP rebars are often used for the internal reinforcement of concrete structures, such as bridge deck slabs, to improve the corrosion resistance. Several studies were conducted to evaluate the static and fatigue behaviour of these elements but the fire resistance still needs further investigation.

Thermal effects on GFRP rebars: experimental study and analytical analysis

Materials and Structures, 2009
The bond mechanism between Glass Fiber Reinforced Polymer (GFRP) bars and concrete is investigated through experimental testing and analytical modeling. This bond depends on several parameters such as temperature. The present paper studies the thermal effect, under high temperature up to 80°C, on bond behaviour at the interface GFRP bars/concrete ...

Service Life Prediction of Gfrp Rebars in an Alkaline Environment

Polymers and Polymer Composites, 2007
This study proposes a model that predicts the degradation of a GFRP rebar exposed to an alkaline environment, and based on this estimate, predicts the service life of the GFRP rebar. The alkaline environment was a pH 12.6 solution of 0.16% calcium hydroxide, 1% sodium hydroxide, and 1.4% potassium hydroxide, and the GFRP rebar was immersed for 300 ...
