Based on given soil data. Soil is a loam with grain the #200sieve. The Liquid Limit = 29, Plastic Limit = 24, friction angleφ = 25 degree, cohesion c = 0.21 tons/sf, unit weight γ=124lb/ft3.
Assumptions: No eccentric or inclined loading. Concretecompressive strength(f'c)=3,000 psi & flexural strength ofsteel, (fs)= 20,000 psi, FS=safety factor= 3, strip footing = 2,200lb/ft2, depth of footing 12"
What is the dimension of a strip footing required to supportthe maximum load to prevent capacity failure, and the requiredsteel in the footing to support tensile stresses?
