Verification of circular RC cross-section
The program verifies a reinforced concrete pile using the method of limit deformation. The maximum allowable strain of concrete in compression is 0.002 - 0.0035.
The degree of reinforcement is checked using the formula:
- Column - check for dominant compression
- Beam - check for dominant bending
Interaction diagram N-M
Usage ratio of concrete cross-section subject to the combination of bending moment and normal force is determined as |0L| / |0R|. Where L is load and R is strength with prescribed eccentricity.
