Section 18.4.1a Initial (at stressing) Compressive Stress Limit
- 0.6 f’ci is the limiting value.
- For sections with multiple concrete strengths, the minimum concrete strength is used to determine the limiting stress.
- For sections with multiple concrete strengths, approximate extreme fiber stresses and centroid stresses are reported.
- No check is made to ensure that the structure is post-tensioned.
