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.
The limiting stress is reported, but reinforcement per section 18.4.1 is added to resist the total tensile force if necessary, so no section will fail this criterion.
Bonded tendons that are at an angle (vertical or horizontal) to the cross section will only have their component perpendicular to the cross section considered.
Usable reinforcing stresses are limited to 0.6fy and 30,000 psi.
No check is made to ensure that the structure is post-tensioned.
User defined reinforcement that is at an angle to the cross section will only have the component perpendicular to the cross section considered.
