Bond Strength of Composite CFRP Reinforcing Bars in Timber
The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members. This article examines the behaviour of carbon FRP (CFRP) bars in timber under direct pull-out conditions. The objective of this experimental program is to investigate the bond strength between composite bars and timber: bar...
متن کاملMonotonic and Cyclic Bond Behavior of Deformed CFRP Bars in High Strength Concrete
Composite reinforcing bars (rebars) that are used in concrete members with high performance (strength and durability) properties could have beneficial effects on the behavior of these members. This is especially vital when a building is constructed in an aggressive environment, for instance a corrosive environment. Although tension capacity/weight (or volume) ratios in composite rebars (carbon ...
متن کاملSplice Strength of High Relative Rib Area Reinforcing Bars
The reinforcing bar deformation patterns currently used in the U.S. were established over 45 years ago. In the interim, material properties and design procedures have changed, resulting in more congested reinforcement, the use of higher strength materials, and the application of coatings to provide corrosion protection. Based on an improved understanding of the interaction between reinforcing s...
متن کاملBond of High Strength Concrete with High Strength Reinforcing Steel
This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
