Q/ Find the number of steel bars for a rectangular foundation and support
an interior column of dimensions (0.350 m x 0.350m). One of the
dimensions of the footing must not exceed 2.5 m.
Notes:
Dead load = 700 kN
Live load = 500 kN
lall(gross) = 250 KN/m²
fy = 420 MPa
%3D
f = 25 MPa
D;= 1 m
Diameter of steel bar = 20 mm
Ø (For beam shear equations)= 0.75
Ø (For tensile reinforcement equations)= 0.9
Y= 17 KN/m3
