A column carries a load of 44 kips and is supported on a 1-foot thick spread footing, which rests on clay. What is the task required for this column?
Calculate the total load on the column.
Size the smallest square footing to support the load.
Determine the height of the column.
Find the allowable soil bearing pressure.
What is the formula for net allowable soil bearing pressure in spread footing design?
q_{net} = q_{allowable} - P_{footing}
q_{net} = P x A
q_{net} = q_{allowable} + P_{footing}
q_{net} = AP

What is the purpose of including both the weight of the column and the weight of the footing in calculations?
To determine the height of the column.
To calculate the total load on the footing.
To find the thickness of the footing.
To measure the area of the footing.
What is the task required for a footing size of 6'-0" X 6'-0"?
Determine if it will be sufficient to carry the given loads.
Calculate the height of the column.
Find the thickness of the footing.
Measure the area of the footing.
What is the formula to determine the area of a square footing required to support a given load?
A = qallowableP
A = P + q_{allowable}
A = P x q_{allowable}
A = Pqallowable
An existing building is suffering from cracks in the exterior walls. The investigating engineer wants to ensure that the foundations are not overloaded. The existing columns carry dead + live load of 45,000 pounds. The footings are 3 ft 6 in. x 3 ft 6 in. x 1 ft 6 in. thick and rest on sandy soil. The soils report estimates the allowable soil bearing pressure to be 2500 psf. Determine whether the existing footings are adequate to carry the load.
Yes, the footings are adequate.
No, the footings are not adequate.
The footings need to be larger.
The footings need to be smaller.
A column carries a load of 22 kips and is supported on a 2 foot thick spread footing which rests on sand (allowable soil bearing capacity 2000 PSF) . Size the smallest square footing (to the next 6 inches) that can support the load.
3 feet
4 feet
5 feet
6 feet
How do you calculate the total load on a column if the dead load is 40,000 lbs and the live load is 50,000 lbs?
95,000 lbs
