A 1 m square footing is founded at a depth of 1.80 m on sand (foundation base thickness is 80 cm) and carries a vertical column load of 150 kN. The underlying sand has drained shear strength parameters of φ’=28°. First, compute the allowable shear load this column can carry using ASD with a sliding factor of safety of 1.1. Next, compute the allowable shear load for the case shear resistance using active and passive earth pressures and without them.

Question
A 1 m square footing is founded at a depth of 1.80 m on sand (foundation base thickness is 80
cm) and carries a vertical column load of 150 kN. The underlying sand has drained shear strength
parameters of φ’=28°. First, compute the allowable shear load this column can carry using ASD
with a sliding factor of safety of 1.1. Next, compute the allowable shear load for the case shear
resistance using active and passive earth pressures and without them.
Expert Solution
Step 1
Given data:
Area of footing=1m2
Depth of footing=1.8m
Depth of foundation=0.8 m
Column load=150 kN
Shear strength parameter,
Factor of safety=1.1
It is asked to compute the allowable shear load
1. Using ASD method
2. Active and passive earth pressure
