Point A is located at coordinates (2.5, 1.5, -10) Point B is located at coordinates (2, 1,-5) Point C is located at coordinates (5, 0,-10) Point D is located at coordinates (6, 1,-5) The load value (Q) on the footing is 100 kN

Problem # 3 A combined footing supports an exterior column 16 in x 16 in carrying a service dead load of 155 kips and a service live load of 165 kips, plus a 22-in.-square interior column carrying service loads of 205 kips dead load and 230 kips live load. The distance between the columns is 18 ft, center to center. For shallow foundations, the allowable soil bearing pressure is 4 ksf and the bottom of the footing is 4 ft below final grade. Design the steel in long direction using fc' 3 ksi, fy 60 ksi.

Designing and detailing of Square Pad footing - BS Code (BS 8110 )

1- Design an appropriate footing/footings to support two columns A and B spaced at distance 2.1 m center-to-center. Column A is 20 cm × 30 cm and carries a dead load of 200 kN and a live load of 100 kN. Column B is 20 cm × 40 cm in cross section but carries a dead load of 300 kN and a live load of 150 kN. Width of footing is not to exceed 1.0 m, and there is no property line restriction. Use f- 28 MPa, f- 420 MPa, q all (net) =200 kN/m², ysoil= 17 kN /m³, and Dr=2.0 m.

A square footing is to be designed to support a column. The design loads on the columnare all downward and concentric. Calculations of the design loads using the required loadcombinations specified by ASCE 7-11 show that the controlling load combination givesa design column load of 450 k. The embedment depth of the square footing is to be 3 ft.The underlying soil has an undrained shear strength of 2,000 lb/ft2 and a unit weight of 109 lb/ft3. The groundwater table is at a depth of 4 ft. Using the ASD method, determinethe minimum required footing width to maintain a factor of safety of 3 against a bearingcapacity failure.

A footing is carrying a design column load of 22 k and a moment of 5 k-ft in one direction.The footing will be founded on sand at a depth of 2 ft. The water table is 3 ft below the groundsurface. Design the footing width for a square footing that will carry the design loads and meetthe presumptive allowable bearing pressure per the International Building Code.
