Question: a footing must be designed to carry a load of...

Question details

A footing must be designed to carry a load of 100 tons. Calculate the required diameter (feet) of a round, flexible footing using an allowable unit end bearing of 3 tsf (round up to the nearest whole foot) Next, calculate the immediate settlement (inches) under the center and edge of this footing if the underlying soil is a sandy clay with E 200,000 psi and u -0.4 1. Repeat problem 1 for a square, flexible footing. Calculate the immediate settlement at the center and a corner. Which footing (square or round) will experience the greatest differential settlement? 2. 3. For the two-layer subsurface profile shown to the right, calculate the immediate settlement (inches) under the center of the flexible storage tank full of water water 62.4 pcf 50 ft diameter 30 Clay Crust 10 E-6x105 psf, μ 0.3 Saturated Clay 1.2 x 10 psf Assume a reasonable value for u A surcharge is applied to the soil profile to the right. Calculate the primary consolidation settlement (mm) if the clay is normally consolidated (NC) 4. Sand Groundwater table Sand Δσ.-90 kPa. Hi 2m. H.-2m. H3 1.5m Sand: Ydry 14.6 kN/m3, Ysat 17.3 kN/m3 Clay: Ysat 19.3 kN/m3, e 0.75, Ce 0.252
