Higher Study | Reinforced Concrete Structures | Bond

In reinforced cement concrete construction, lap splices are not recommended to be used for rebars when the bar diameter is more than:
By what value the bond stress of deformed bars is increased in tension?
In limit state design, permissible bond stress in the case of deformed bars is more than in the plain bars by what percentage?
The resistance offered to slipping of steel bars from concrete is due to: i. Pure adhesion ii. Frictional resistance iii. Mechanical resistance Which of these is/are correct?
What shall be maximum allowed anchorage length of U-type hook in a RC compression member?
Which of the following statements in regard to the design considerations for bond and anchorage is INCORRECT?
At which condition the splicing of the reinforcement bars in R.C.C. beams is required?
Consider a reinforcing bar embedded in concrete. In a marine environment this bar undergoes uniform corrosion, which leads to the deposition of corrosion products on its surface and an increase in the apparent volume of the bar. This subjects the surrounding concrete to expansive pressure. As a result, corrosion induced cracks appear at the surface of concrete. Which of the following statements is TRUE?
Which one of the following formulas is correct to express the bond stress Bs? Assume shear force at the section = Q. Lever arm = Jd and sum of the perimeter of bars = S.
