Behavior of Damaged Continuous Reinforced Concrete Beams Repaired by CFRP Sheets

چکیده
Despite the widespread use of RC continuous beams, performance these when repaired via Fiber Reinforced Polymer (FRP) composite material, has received less attention. Furthermore, several features flexural aspect beams still demand experimental and analytical evaluation. However, many anchoring methods have been developed to delay premature failure in which are strengthened with FRP materials. The plan this study consists eight cast dimensions (150*250*2800) mm considering length clear span is 1300mm. Except for one, all specimens were attached Carbon sheets about 70% negative positive moment zones beyond a predetermined damage level. Moreover, suggested modifying end-anchor technique adding CFRP layers (45, 65, 95) % as ratios. According results, optimal percentage restored ultimate capacity was 108.8% peeling-off concrete cover mode, obtained from using an two sheet. Also, increasing ratio leads decline toughness ductility values. In addition, it possible repair structure 95% rather than remove it.

Flexural Testing of High Strength Reinforced Concrete Beams Strengthened with CFRP Sheets
The objective of this study is to investigate the effectiveness of externally bonded CFRP sheets to increase the flexural strength of reinforced high strength concrete (HSC) beams. Four-point bending flexural tests to complete failure on six concrete beams, strengthened with different layouts of CFRP sheets were conducted. Three-dimensional nonlinear finite element (FE) models were adopted by A...
متن کاملStrut Deformation in CFRP-Strengthened Reinforced Concrete Deep Beams
Strut-and-tie model (STM) method evolved as one of the most useful designs for shear critical structures and discontinuity regions (D-regions). It provides widespread applications in the design of deep beams as recommended by many codes. The estimation of bottle-shaped strut dimensions, as a main constituent of STM, is essential in design calculations. The application of carbon fibre reinforced...
