1. Design a wall footing for the following conditions. Service dead load is 6 kips/ft, service live load is 8 kips/ft. Soil unit weight is 120 lb/ft?. Allowable soil pressure, qa is 4000 psf. The base of the footing is placed 3 ft below the ground surface. Wall is 12 in, thick. Geotechnical analyses have determined the width to be 4 ft. fe' = 3500 psi normal weight concrete, and fy = 60 ksi. Note: you don't need to design...
HW#10 Given the following column loading and footing information, determine the size of a mat foundation shown below: I 15 Column Information: Column A: Live load = 40 kips, Dead load = 50 kips Column B: Live load = 80 kips, Dead load = 100 kips. Distance between two columns: 15 ft. W soil = 120 psf 24" I CA C. Footing information: Distance from column A to edge of footing: 1 ft. Allowable soil bearing capacity = 3000 psf...

A square footing is founded at 3-ft depth below ground surface as shown in Fig1, The factored axial load acting on the square footing is 140 kips, Determine the size of the footing (B x B) if the Factor of Safety (F.S.) is 3.0. Ground surface ЗА B-? Silty Sand Fig.1 A 68-ft long pre-stressed concrete pile with square cross section (14 inch) is driven into the soil profile shown in Fig. 2. Compute the ultimate compressive load...
CVE 313- 1- Design a square footing for the interior column shown in the figure. The column carries 2 k 't of uniform live load and 1.5 k/t of uniform dead load (including the self weiht of the structure), the base of the footing is 5 ft below grade, the soil weight is 100 lb/ft', and q," 5000 psf. and concrete unit weight is 150 lb/ (25 points) NOTE: Your design should only include the following (one-way shear, two-way shear,...

2. A 5-ft square, 2-ft deep spread footing is subjected to a concentric vertical load of 60 k and an overturning moment of 30 ft-k. The overturning moment acts parallel to one of the sides of the footing, the top of the footing is flush with the ground surface, and the ground water table is at a depth of 20 ft below the ground surface. Compute the minimum and maximum bearing pressures, d show the distribution of bearing pressure in...

1. A continuous footing is shown in the figure below. Using Terzaghi's ultimate b.c. equation and bearing capacity factors, determine the gross allowable load per unit area (qall) that the footing will carry. Given: y 112 pcf, c' 450 psf, ' 22, Dr 4 ft, B 3 ft, and F.S. 3. 4all Unit weight of soil y 2. Repeat problem #1 using the general bearing capacity equation. Use the appropriate assumptions
The total settlement for clay being the elastic settlement
plus the primary consolidation settlement.
2. A foundation carrying 150 kips needs to be designed in New Jersey (frost depth 3 ft) for a FOS of 3. The founding soil is deep normally consolidated clay deposit with average Su value of 1100 psf, and saturated unit weight of 130 pcf and a moist unit weight of 110 pcf with water table at 3 ft depth. The laboratory tests performed on undisturbed...
