VI. The height of a ground floor interior column in reinforced concrete frame with-out sides-way from the foundation level to the top of the slab is 4m. The column has a square section of b=h=250mm. The concrete grade is of C25, the reinforcements is 4 numbers and the diameter is 16 bars of HRB335 arranged symmetrically in the section. If the axial load is 650kN, check the appropriateness of this Member. Data : C25 concrete fc=11.9MP Because the longer side is less than 300mm, so fc=D0.8X11.9MP=9.52MPA HRB335 steel (f = 300N / mm ).

Concrete structure design 

VI. The height of a ground floor interior column in reinforced concrete frame with-out
sides-way from the foundation level to the top of the slab is 4m. The column has a
square section of b=h=250mm. The concrete grade is of C25, the reinforcements is 4
numbers and the diameter is 16 bars of HRB335 arranged symmetrically in the
section. If the axial load is 650kN, check the appropriateness of this Member.
Data : C25 concrete fc=11. 9MP
Because the longer side is less than 300mm, so fc=0.8×11.9MP-9.52MPA
