Verification of rectangular RC cross-section under N, M, V
Verification of rectangular RC cross-section under N, M, V
The cross-section is rectangular, unilaterally reinforced and loaded by the bending moment and normal compression force. The program verifies a reinforced concrete section using the method of limit deformation. The maximum allowable strain of concrete in compression is 0,002 - 0,0035. Compression reinforcement is not taken into account.
The computed degree of reinforcement is checked using the following expressions:
where:
Shear
First, the program computes the ultimate shear strength of concrete VRd1.
where:
If the ultimate shear strength of concrete is exceeded, the ultimate shear strength VRd2 is checked.
where:
Next, the necessary reinforcement area is given by:
