Design a reinforced concrete to support a concrete wall in a relatively large building. The wall is 12 inches thick and carries unfactored dead and live loads of 10 kip/ft and 12.5 kip/ft respectively. The allowable soil pressure is 5,000 psf and the its density is of 120 pcf. The bottom of the footing should be at 5 … See more We will design our footing to resist its load and check it for: 1. Soil bearing pressure 2. Shear resistance 3. Flexural resistance We enter the given information directly into ClearCalcs. Since in this case we are given the depth to … See more The first thing to do is to determine the width of our footing, which is determined by the allowable soil bearing capacity. We need to estimate the required thickness of the footing, since the self-weight of the footing is usually … See more The last failure mode which we need to check is the bending of the footing. We essentially have a cantilevered out concrete slab, with a uniformly distributed load from the soil's … See more After the little sneak peek we saw when checking soil bearing, we definitely want to take a look at shear. This is usually what will govern the footing's thickness in design. Since we are now dealing with concrete design, we … See more Webare so numerous that footings cover most of the available foundation area.
