A strip footing foundation supports a bearing wall for an industrial building. The foundation bears on a cohesionless soil where the unit weight is 18 kN/m³
and the angle of internal friction is 30°. The footing depth-to-width ratio is 1. Estimate the foundation settlement (in mm) expected if the original design for static conditions included a factor of safety of 3 but an earthquake event results in a ground motion peak velocity of 0.23 m/sec and the ground acceleration coefficient A is 0.3.
