Unit 5: Column Footings:
1.
Design
an isolated square footing for the column of 300mmx300mm size carrying capacity
of 1000KN taking safe bearing capacity of the soil as 300KN/m2. Use
M20 concrete and Fe 415 steel.
2.
Design
an isolated Rectangular footing for the column of 300mmx450mm size carrying
capacity of 1000KN taking safe bearing capacity of the soil as 300KN/m2.
Use M20 concrete and Fe 415 steel.
3.
Design
a combined Rectangular footing for column of 300mm x 400mm size carrying
capacity of 1200KN and 1800KN. Spacing between Columns is 3m. Safe bearing
capacity of the soil as 250KN/m2. Width is limited to 1.5m. Use M20
concrete and Fe 415 steel.
4.
Design
a combined Trapezoidal footing for column of 300mm x 400mm size carrying
capacity of 1200KN and 1800KN. Spacing between Columns is 3m. Safe bearing
capacity of the soil as 250KN/m2. Width is limited to 1.5m one end
and 2.5m at other end. Use M20 concrete and Fe 415
Unit 6: Columns
5.
Design
a Circular column to carry a factored axial load of1200 KN. Use M20 concrete
and Fe-415 steel. Show the details of reinforcement.
6.
Design
a Rectangular column of 300mm x 450mm to carry a factored axial load of1500 KN.
Use M20 concrete and Fe-415 steel. Show the details of reinforcement.
7.
Design
a Square column 300mmx300mm size to carry a factored axial load of1200 KN and
100KN-M moment. Use M20 concrete and Fe-415 steel. Show the details of
reinforcement.
