The detail of column and pad footing are as under:                                   

The detail of column and pad footing are as under:                                                                             [5]

                Size of column: 300 mm x 300 mm.                                                                                           

Live load on column: 900 kN.

         

Dead load on column: 1200 kN.

         

Soil Bearing Pressure: 180 kN/m² and Depth of footing as 400 mm

         

Nominal cover: 50 mm and 20 mm diameter bars for reinforcement

  1. Design the footing for bending.     
  2. Check the footing in two way shear.         

iii. Write the reasons for considering the service loads for dimensioning of the footing and factored loads for calculating the factored soil pressure.

  1. Consider fcu=40 N/mm2, fy=460 N/mm2, severe exposure condition and 2 hours of fire resistance for all the questions.
  2. Use B.S 8110 for all your calculations and references.
  3. Draw the structural detailing after designing each member for all the questions.
  4. Unit weight of concrete as 25 kN/m3
