Verification of rectangular RC cross-section under M, V
Verification of rectangular RC cross-section under M, V
The cross-section is rectangular, reinforced on one side and loaded by the bending moment Md.
The ultimate moment is provided by (Art. 5.2.7):
The program further checks whether the location of neutral axis x is less than the limit location of neutral axis xlim given by (Art. 5.2.7.1):
The computed degree of reinforcement is checked using the following expressions (Art. 3.1.4.3, Art. 3.1.4.6):
Shear
First, the program computes the ultimate shear strength of concrete Qbu (Art. 5.3.3, Appendix 9).
where: | for: | | is: κq = 1,25 |
for: | | je κq = 1,50 | |
for: | | je κq = 1,60 |
If the ultimate shear strength of concrete is exceeded, the ultimate shear strength Qmax is checked (Art. 5.3.2.1).
Next, the necessary reinforcement area is given by (Art. 5.3.4):
where (Art. 5.3.5):
The magnitude of c is bounded by the following expression:
