Expert Solution
Step 1: Given:

Dimension of rectangular short tied column = 300 x 450 mm

Number of reinforcement bars = 6

Diameter of reinforcement bars = 28 mm

Diameter of ties = 10 mm

Spacing of ties = 300 mm

Compressive strength of concrete, f’c = 28 MPa

Yield strength of steel, fy = 420 MPa
