| Title |
A Study on the bond characteristics of deformed reinforcing bars and the influence of the deformation in the concrete members |
| Abstract |
The slip resistance is occurred by the key action of the knob in case of deformed bars while by frictional resistance in case of the two should be clearly distinguished. The key action affects concrete around the bar and causes splitting crack. As splitting cracks and cone cracks are developed in the cross section of concrete. This study clarified splitting crack whose variation is a diameter of steel bar and concrete clear cover thickness. Also the bond strength was analyzed in crack line of section and longitudinal direction of member. |
