5. A square footing is 4 mx 4 m in plan. Determine the gross allowable load, Qall, that the square footing can carry. Use the general bearing capacity equation and a factor of safety F.-4). Given unit weight of soil y = 19 kN/m, c' = 0 kN/m, 6 - 35°, D-2 m. The load is applied vertically and the groundwater is very deep. Qall = ? B = 4 m

the foot) for your steel pile. Q_all = 20 tons
An 18-in diameter smooth steel pile is driven into dense sand. Find the depth the pile needs to be driven (to the foot) using the following soil profile to achieve a capacity of 20 tons. Factor of Safety 2 K0.75 Water Table@10 D-20x 30 2.0 ALT lon e TABLE...
You are designing the foundation for a natural gas import terminal. The subsurface is
predominantly alluvial clays in the upper 6 – 15 m below the ground surface (BGS), which
has resulted in large post construction settlements on nearby structures. To prevent large
settlements and differential settlements, the new gas tanks will be supported by pile
foundations. You have determined that pre-stressed concrete (PSC) piles are the most
economical solution. The pile layout will be a square with center-to-center spacing...
An eccentrically loaded (one-way eccentricity) square foundation, given: B = 5 ft, L = 5 ft, Df = 4 ft, e = 0.5 ft, γt = 110 pcf, c’=0 and ϕ’ = 30°. Note the ground water table is at great depth below the footing. Calculate the general bearing capacity to determine the maximum allowable load that the foundation can carry using Meyerhof’s effective area method for a FS of 3.
Problem 5-Bearing Capacity of Shallow Foundation (20 pts) For a square footing foundation, the following are given: B 3.0 m (width), D 1.2 m (depth). Y=20 kN/m3, = 32°, c' = 50 kPa, Use Terzaghi Equation and a factor of safety of 2.5 to determine the allowable bearing capacity and the maximum column load to cause bearing capacity failure. Assume that general shear failure occurs in soil. When Oar C S
