Unformatted text preview: 3. A 24" wide, square, prestressed concrete pile will be driven into the clay profile at right. Determine the pile length required to support an allowable load of 220 tons. Design the pile to meet a Factor of Safety = 2. 4. A proposed column is to be supported by a 1.5 m wide, 0.5 m deep square footing. The footing will be founded within a silty sand that has the following properties: m = 18 kN/m 3 , c’ = 0 and ’ = 30°. The high groundwater table has been determined to be 3 m below the ground surface. The local building code requires a Factor of Safety (FS) of 2.5. The load is applied eccentrically with e = 1.0 ft . Use the general BC Meyerhof equation and find the ultimate load, Q u , in kips if. 220...
