The figure shows the section of a gravity
dam (non-overflow portion) built of concrete.
Calculate (neglecting earthquake effects) the
maximum vertical stresses at the heel and toe of the
dam. Assume weight of concrete = 23.5 kN/m, and
unit length of dam. Allowable stress in concrete
may be taken 2500 kN/m and assuming yw = 9.81
kN/m.
