A 7 foot-square footing is embedded 3 feet below the ground surface and is supported on a clayey sand fill having a total unit weight of 130 pcf. Groundwater is at 8 feet below the ground surface. Consolidated undrained triaxial tests with porewater pressure measurements on three "identical" samples suggest the fill has a drained friction angle of 29 degrees and drained cohesion of 50 psf. What is the allowable bearing capacity for this footing for a factor of safety of 3 AND what is the maximum allowable column load the footing can safely support based on this factor of safety?

Question

A 7 foot-square footing is embedded 3 feet below the ground surface and is supported on a clayey sand
fill having a total unit weight of 130 pcf. Groundwater is at 8 feet below the ground surface.
Consolidated undrained triaxial tests with porewater pressure measurements on three "identical"
samples suggest the fill has a drained friction angle of 29 degrees and drained cohesion of 50 psf.
What is the allowable bearing capacity for this footing for a factor of safety of 3 AND what is the
maximum allowable column load the footing can safely support based on this factor of safety?

2. Change the footing dimension in the question below to a strip footing with width of 6 ft. and find the settlement using Schmertmann's modified method to calculate the required settlement. Example 8-2: A 6 ft x 24 ft footing is founded at a depth of 3 ft below ground elevation with the soil profile and average N160 values shown. Determine the settlement in inches (a) at the end of construction and (b) 1 year after construction. There is no groundwater. The footing is subjected to an applied stress of 2,000 psf. Ground Surface Clayey Silt 3 ft Y = 115 pcf; N160= 8 Sandy Silt B = 6 ft 3 ft Y = 125 pcf; N160= 25 Coarse Sand 5 ft Yt = 120 pcf; N160= 30 Sandy Gravel 25 ft Yt = 128 pcf; N160= 68
Scenario The wall footing at right is to be constructed to carry an inclined load at 85 degrees with the horizontal, as shown. Assume that there is impenetrable bedrock below the Sample point shown in the figure. 1) Calculate the expected primary settlement of the soil at the Sample point. Also, determine the time it will take for 60% of the expected primary settlement to occur. 2) Determine the factor of safety against bearing failure of the soil for the wall footing if qult of the soil is 160 kN/m2.
An isolated footing having dimensions of 1.5m x 2.2m is provided at a depth of 1.2m in a stratum of cohesionless soil having a relative density of 71%. Determine the bearing capacity factors Nc, Nq and Nγ as per IS code.
subject
A square footing 5 ft by 5 ft supported on a sandy stratum is designed to carry a column loading of 250,000 lb. The unit weight of the sands underlying the footing location vary between 120 and 125 pcf. Estimate the foundation settlement to be expected using the subgrade reaction method. (Neglect the weight of the footing.)
