8. To comply with architectural requirements, a column is a non-sway
frame is of T section. fy = 415 MPa, fc' = 27.5 MPa, 10 mmø ties, clear
cover is 40 mm.
(a) Compute the location of the geometric and plastic centroid
(b) If the T section is reinforced such that the plastic centroid of the
section falls at 280 mm from the extreme left along the x axis, determine
the bending moment Mu induced by a factored load Pu = 3200 KN acting
along x -a xis at 400 mm from extreme left.
