A long retaining wall is braced by wood shores set at
an angle of 30° and supported by concrete thrust blocks, as
shown in the first part of the figure. The shores are evenly
spaced, 3 m apart.
For analysis purposes, the wall and shores are idealized
as shown in the second part of the figure. Note that the
base of the wall and both ends of the shores are assumed to
be pinned. The pressure of the soil against the wall is
assumed to be triangularly distributed, and the resultant
force acting on a 3-meter length of the wall is F 190 kN.
If each shore has a 150 mm 150 mm square cross
section, what is the compressive stress sc in the shores?
