Single and Double Pile Two-Way Shear

Please refer to sections 4.16.8 and 4.16.9 for a discussion on the two-way shear check performed on single and double piles. The pile two-way shear critical section is taken at 1.5d + 6d_p /10

The capacity check that is performed is:

v = \frac{P}{U d} \leq v_{c} \min {\begin{matrix} 0.8 \sqrt{f_{c u}} \\ 5 {N/mm}^{2} \end{matrix}
