Due to the linear elastic properties of the FRP bars up to failure, the traditional definition of ductility applied to the steel reinforced structures cannot be directly applied to the structures reinforced with FRP reinforcement. Several methods such as the energy-based method or the deformation-...
Experiments on integrating ANN with fuzzy logic to calculate the bond strength of steel bars with concrete were conducted, and works proved the ANN-based model to be more capable of accurately predicting the ultimate bond strength than the FL-based model [24]. An investigation on ANN models ...
Each specimen was prepared with a 12-D22-type SD40 main rebar, reinforced with shear reinforcement D10 steel bars at 250-mm intervals. A sub, with high stiffness, was installed at the top of each specimen to provide confinement for the columns. The average vertical load on columns was ~...
1.What is Rebar? Rebar is a steel bar that is used in concrete construction. By adding these reinforcing steel bars, you're creating reinforced concrete. Whether your project includes floor slabs, walls or posts, rebar helps k...
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...
However, less attention has been paid to the twin confining effect of FRP and steel reinforcement on the cyclic behavior of concrete. In this study, a total of 32 concrete specimens were tested under monotonic and cyclic axial compression. The specimens were confined using steel bars or/and ...
