ULS Stress / Strain summary for section with HOGGING moment
—————————————————————————————————————————————————————————————————
height of neutral axis = 193.398 mm
at centroid of outermost 25% of tendon area:
height = 1040.0 mm
strain in PC concrete = -0.0153
initial strain in tendon = -0.0058
total strain in tendon = -0.0212
yield strain = -0.005 - fpu /Es .γm = -0.0131
Tendons are fully yielded, therefore the full ultimate capacity may be applied
to the section. (clause 6.3.3.1)
