A square column 410 x 410 mm (along with 4 No. 16 mm bars) carries a dead load of 1020 kN and an imposed load of 410 kN. The foundation soil has a safe bearing capacity of 200 kPa. Fe, 415 is to be used for reinforcement. You have to design a square footing. The column and the foundation are constructed of M20 grade concrete.
Ans:
Plan Area
No details are given regarding the depth of foundation and unit weight of soil. Hence we will assume that the weight of footing and soil above it is 10% of applied load.
Total load = 1020 + 410 + 0.1 x 1430 = 1573 kN
Area required here = 1573/200 = 7.865 m2
Adopt 2800 mm x 2800 mm square footing.
Ultimate Soil Reaction
Factored loads have to be taken
Weight of footing is not to be considered
Design load = 1.5 DL + 1.5 LL = 1.5 x 1430 = 2145 kN
Soil reaction = 2145/(2.80 x 2.80) = 273.6kPa
In the drawing, the weight of the block on the table is 380 N and that of the hanging block is 215 N. Ignore all frictional effects, and assuming the pulley to be massless.
