This paper presents the bond behaviors of deformedsteel rebarsin engineered cementitious composite (ECC) and concrete under direct pullout condition. A total of 12 specimens were casted and tested, it was found that the deformed steel rebar has a much higher bond strength in ECC than in concrete...
16.12. Average fatigue life in hours of lap shear joints exposed to cyclic stress while immersed in water at 40°C (from Briskham, 1999). The pressing environmental need to remove toxic hexavalent chromium from pretreatment tanks created an urgent need for the development of a viable chromate-...
Both concrete and mortar substrates were prepared for bonding FRP sheets. Cyclic loading way was applied on all composite beams and the interface tension-softening diagram was derived through improved J-integral method and then verified through FEM analysis. Figure 20 shows the experimental ...
The bond mechanism of Fiber Reinforced Polymer (FRP) rebar to concrete was studied. Five different types of 12.7 and 12.0-mm rebar subjected to different surface treatments were tested, and the bond mechanism was compared with that of untreated FRP rods and ordinary deformed steel. High bond val...
This has garnered increasing attention from scholars, who have begun to focus on the research regarding the application of FRP reinforcement [16,17,18,19,20]. FRP bars are used in concrete as reinforcing steel bars, which have the advantages of chloride ion corrosion resistance, high tensile ...
Bond performance under cyclic loads Bond strength between concrete and non-shrink grouts that are common in accelerated bridge technology (ABC) and other prefabrication practices Developing a numerical model by machine learning based on existing literature and new experimental results to predict bond shear...
This experimental study mainly focuses on comparing the bond behavior of carbon fiber reinforced polymer (CFRP) rebars in a high strength concrete block under monotonic and cyclic loading conditions. In addition to the loading procedure, various embedment lengths were also taken as test parameters. Ob...
A direct approach to resolve the corrosion problems would be to replace the steel reinforcement with fiber-reinforced polymer (FRP) bars in concrete structures [5]. Due to the extensive use of nonmetallic technology of reinforcements, several design guidelines have been published especially Sensors ...
