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 Mu.
The ultimate moment is provided by (Ch. 10, Art. 10.2.7.3, Art. 9.3.2.1):
The computed degree of reinforcement is checked using the following expressions (Art. 10.5.1):
The program further checks whether the location of neutral axis c is less than the limit location of neutral axis cmax given by (Art. 10.3.2):
Shear
First, the program computes the ultimate shear strength of concrete Vc (Art. 11.2.1.1).
If the ultimate shear strength of concrete is exceeded, the ultimate shear strength Vmax is checked (Art. 11.2.1.1 + Art. 11.4.7.9).
Next, the necessary reinforcement area is given by (Art. 11.4.7):
where (Art. 11.4.2, Art. 9.3.2.3):
