Example 11 (TBEC 2018 section Z-l-2.1.): Reinforced concrete building with 6 floors and 1 basement will be constructed on a soil deposit with shear strength parameters of c, = 250 kPa and $µ = 0°. Unit weight of the soil is given as 19 kN/m³. Depth of the foundation is 3.5 m and dimensions of the raft foundation is 14m x 19m. Under the static condition and with 1.4DL+1.6LL load combination, maximum foundation pressure is determined as 364 kPa whereas, in earthquake condition with 1DL+1LL+1E, maximum foundation pressure is given as 216 kPa. Calculate the ultimate bearing capacity by using General Bearing Capacity equations and determine whether the foundation is safe or not.

A planned subterranean vault for heavy power transformer equipment is required in an area where a thick deposit of weak soils exists. The vault is 8 m by 12 m in plan area and is 4 m high. The soil unit weight is 15 kN/m3. The approximate weight of the vault structure plus included equipment is 5,500 kN. It is proposed to apply the floating foundation concept to the design–installation of the vault, to eliminate the expense of deep foundation support. Does the proposal appear reasonable?
Compute the increase in vertical stress beneath the center of the foundation (i.e., relative to the stresses that existed prior to construction) at depths of 0 ft, 3 ft, 9 ft, and 15 ft beneath the base of the footing (i.e., at depths of 2 ft, 5 ft, 11 ft, and 17 ft beneath the ground surface). 2a.

A 100'x50' mat foundation (also called slab-on-grade) will be placed at the site shown in Figure 1. Calculations show that the foundation will cause an average increase in vertical stress in the clay layer of (a) 850 psf under the foundation center, and (b) 350 psf under the foundation corner. Find the foundation settlement due to the consolidation of the clay layer both at the foundation center and the foundation corner. Can the resultant differential settlement be considered tolerable?
