Pile caps in a bunched square reinforcement pattern exhibit no significant mechanical advantage over pile caps in a grid reinforcement pattern. Square pile caps in a grid reinforcement pattern perform better because...

... & cracking reinforcement The bond between concrete and reinforcement allows for the transfer of forces and their composite response. Bond forces have been found to depend on three main physical phenomena, namely adhesion, friction and mechanical interlocking between the ribs of the reinforcement...

...Ramesh Gopal; Sethumadhavan Krishnachandran Reinforced concrete (RC) in aggressive environments has higher concrete clear cover provided to protect the reinforcement against corrosion. However, providing such higher cover in severe environments could result in increased crack widths...
