PILE FOUNDATION A square pile cap shown consists of five piles. The foundation is subjected to an ultimate vertical load of
1050kN
on a
450mm
square column and moment of
160kN-m
. The diameter of piles is 0.30
m,f_(c)^(')=28MPa
and
f_(y)=276MPa
, effective depth of footing
=0.6m
. Reduction factors for moment
=0.90
and for shear
=0.75
, respectively. Compute the maximum and minimum pile reactions at ultimate loads. Determine the punching shear stress around the square column. Determine the critical beam shear stress. Design the number of
28mm
diameter bars considering the critical design moment.
