Question
A tied column 350 mm x 600 mm in cross section is reinforced with 6-28
mm Ø bars arranged as shown in the figure. It is assumed that the column
section has a strain on its compression edge equal to 0.003 and has a
tensile strain of +0.002 on its outer edge. f = 27.6 MPa. fy = 414.6 MPa.

Determine the total compressive force of the steel reinforcement
considering that its compressive stress is reduced by 0.85 f' to account
for the holes in the concrete.
2 Determine the nominal axial load that causes this strain distribution in the
column section.
3 Determine the nominal moment that causes this strain distribution in the
mn section.
