Refer to Problem 7.15. If the design earthquake parameters are V = 0.35 m/s and A = 0.3, determine the seismic settlement of the foundation. Assume FS = 4 for obtaining static allowable bearing capacity.

Problem 7.15.

The following are the average values of cone penetration resistance in a granular soil deposit.

Depth (m) …………………… Cone penetration resistance, q_c (MN/m²)

2 ………………………………………… 1.73

4 ………………………………………… 3.6

6 ………………………………………… 4.9

8 ………………………………………… 6.8

10 ……………………………………..… 8.7

15 ……………………………………….. 13

For the soil deposit, assume γ to be 16.5 kN/m³ and estimate the seismic ultimate bearing capacity, q_uE, for a continuous foundation with B = 1.5 m, D_f = 1.0 m, k_h = 0.2, and k_v = 0. Use Eqs. (7.47) and (7.48).
