Q2: Compute the total stresses, which induced from geostatic stress and increase vertical stress from circular foundation under points A and B to 3 and 6 m depth from the base of the foundation. The foundation was constructed at 2.0 m below the natural ground level (NGL). The surface load intensity is 330 kN/m². R1= 4, (calculate R2 from the drawing, do not assume it). Assume any other parameter you need in your answer.

We are interested in the forces at a footing due to dead, live, and earthquake loads. The horizontal forces are 0.8 for dead, 1.0 for live, and 4.4 for earthquake. The vertical forces are 2.6 for dead, 3.5 for live, and 3.9 for earthquake. For vertical forces, positive indicates compression and negative indicates uplift. Apply all the relevant load combinations. All forces are in kips. Determine the largest uplift force in kips to two decimals. Since uplift is negative, provide a negative answer. If your calculations show that there is no uplift, enter zero. × -10.52

We are interested in the forces at a footing due to dead, live, and earthquake loads. The horizontal forces are 0.6 for dead, 0.9 for live, and 4.9 for earthquake. The vertical forces are 2.5 for dead, 3.7 for live, and 3.8 for earthquake. For vertical forces, positive indicates compression and negative indicates uplift. Apply all the relevant load combinations. All forces are in kips.   Determine the largest compressive vertical force in kips to two decimals.
