A building will have a factored column load of 300 kN. The column is to be supported on a square spread footing underlain by a soil with the follow properties: c' = 5 kPa, o' 35°, y = 18.5 kN/m³. The groundwater table is at a depth of 15 m and the footing will be located 0.5 m below the ground surface. Determine the required footing size if Þ = 0.5. Use Terzaghi's bearing capacity equation for a square footing. Solve for 'B', making sure to use the reduction factor Þ; trial and error is the easiest way to solve for 'B'. Recommend a "reasonable" dimension for construction/design purposes.
Foundation example
Foundation and Retaining Wall Design 3 Decimal Places
A structural engineer finished a design of a library. They determine that each column will carry 1000 lbs. the soil beneath the footing has the properties: gamma= 130 pcf, c= 75psf, phi= 40 degrees. The groundwater table is of great depth so it’s no concern. Sketch figures. What is the minimum size of the footing for a factor of safety of 3? Case 1: assume square footing Case 2: assume round footing
Subject: Principles of Foundation Design (Use NCSP) A rectangular footing is to be used to support a 300x400 (*400mm side is parallel to the long dimension of the footing) column loaded with 420 kN dead load and 540 kN live load. One side of the footing is 4.0m. Use effective soil pressure of 70 kPa. f'c=35 MPa and fy=420 MPa. Use minimum steel ratio for longitudinal bars as 0.0018. •Calculate the required thickness of the footing (mm) based on wide beam shear. db=16mm. Size of footing should be multiples of 10mm (Answer: 300) •Calculate the required thickness of the footing based on two-way shear. db=16mm (Answer: 430) • Calculate the required number of 16mm bars along long direction. . Use the governing thickness based on shear requirements. (Answer: 22)
