Verification of circular RC cross-section
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. Concrete strength η*fcd is reduced by ten percent due to shape of cross-section (Art. 3.1.7).
The degree of reinforcement is checked using the formula:
- Pile
Ac < 0,5m2 | ρmin = 0,005 |
Ac > 1m2 | ρmin = 0,0025 |
where: | Ac | - | cross-section area of pile |
intermediate values are interpolated
- Column - check for dominant compression
- Beam - check for dominant bending
where: | d | - | pile diameter |
As | - | cross sectional area of reinforcement |
Standard values of coefficientsρmin, ρmax are built-in the program – these values can also be inputted by the user depending on the selected National annex.
