Question
An eccentrically compressed column is a rectangular section. The dimensions
of the section are b × h = 400 mm × 600 mm, a, = a = 40 mm, and lo = 4.6 m.
The strength of the concrete is fe = 16.7 N/mm. The properties of the rein-
forcement are f = fy = 300 N/mm², E, = 2 × 10° N/mm². If the axial com-
pressive force N. = 1200 kN and the moment M = 600 kN:m are applied on
the column and the section is asymmetrically reinforced,
1. Determine A, and A.
2. If 4920 compression steel bars have already been placed (A', = 1257 mm?),
determine Aş.
3. Compare the calculation results and analyze the difference. 1
