N = 0.4fcuAc + 0.8 fyAsc

N = capacity of concrete

Fcu = concrete strength (N/mm2)

Ac = cross section of concrete column

fcu = yield strength of steel (N/mm2)

Asc = steel content in a column

Given that fcu = 30N/mm2 and fy = 460N/mm2.

Assuming percentage of steel reinforcement in a rectangular concrete column is 2%,

determine the capacity of the column.

Ac = 300 × 400 = 120,000

Asc = 2 % × 120,000 = 2,400


= 0.4(30)(120000) + 0.8(460)(2400)

= 1440,000 + 883,200

= 2323200 N = 2323.2kN

Thus, this column can sustain any ultimate load below 2323.2 kN.
