Step 1 of 4      Determine the apparent lateral pressure ():
Where, unit weight is      Height is H      Substitute for , 8 m
for      Since the soil is sandy, the pressure diagram will be
rectangular throughout.    • Step 2 of 4      The diagram
illustrates how the pressure envelops are for the given braced
cut in sand. Note that are the partition forces in the pressure
envelope for strut B    • Step 3 of 4      Take moments to
evaluate the strut loads,     • Step 4 of 4      Calculate the
total strut forces by multiplying the obtained strut forces per
unit length by the spacing of the struts in plan (S’).      At
point A:      At point B:      At point C:      Therefore, the
strut load at point A is      The strut load at point B is
The strut load at point C is      These are the forces needed to
be carried by the individual struts and to select the section
properties of
