Question
A large sign is to be supported on two steel poles, each of the poles which will be
supported by a 500 mm diameter drilled shaft embedded into a stiff silty clay. The lateral
wind load will be 5.4 kN and will act at a height of 8 m above the ground surface. This
load will be equally distributed to the two poles. Assume the undrained shear strength for
stiff silty clay is 80 kPa. Assume a factor of safety of 3. Using a rigid analysis (Brom’s
Method), 1) compute the required depth of embedment and 2) the maximum moment in
each drilled shaft.
