A spreаd fооting, 10 ft x 10 ft in size is designed tо support а column loаd of 380 kips. It will be built at grade (i.e., at the ground surface, duly leveled and compacted) at a site underlain by granular soil with total unit weight of 116 pcf and friction angle of 33 degrees. The water table is at the ground surface. What is the bearing capacity of the soil? What is the factor of safety? Shallow foundations typically require a minimum FS of 3. Is the calculated FS adequate? Solve using the following calculation steps and selecting your answer for each step by filling in its blank space using the correct value from the options provided for each. Applicable unit weight = [BLANK-1] pcf. (choices: 116 or 53.6 or 62.4) Bearing factor, N c = [BLANK-2]. (choices: 26.1 or 38.6 or 35.2) Bearing factor, N q = [BLANK-3]. (choices: 26.1 or 38.6 or 35.2) Bearing factor, N γ = [BLANK-4]. (choices: 26.1 or 38.6 or 35.2) Shape factor, s c = [BLANK-5]. (choices: 1.68 or 0.6 or 1.65) Shape factor, s q = [BLANK-6]. (choices: 1.68 or 0.6 or 1.65) Shape factor, s γ = [BLANK-7]. (choices: 1.68 or 0.6 or 1.65) Bearing capacity, q = [BLANK-8] psf. (choices: 5660 or 3962 or 3800) Original design load = [BLANK-9] lbs. (choices: 380000 or 640000 or 116000) Applied stress at the foundation level due to the column load = [BLANK-10] psf. (choices: 3800 or 6400 or 1160) Factor of Safety, FS (rounded value) = [BLANK-11]. (choices: 1.5 or 3.5 or 4.5) Is the FS adequate? [BLANK-12]. (choices: yes or no or barely)
