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 to 0,0035. Compression reinforcement is not taken into account. Minimum eccentricity is applied: (Art. 6.1(3)):

The computed degree of reinforcement is checked using the following expressions (Art. 9.2.1.1):

Standard values of coefficients ρmin, ρmax are built-in the program - these values can also be input by the user depending on the selected National annex.

Shear

First, the program computes the ultimate shear strength of concrete VRd,c (Art. 6.2.2(1)).

where:

If the ultimate shear strength of concrete is exceeded, the ultimate shear strength VRd,max is checked (Art. 6.2.3(3)).

Next, the necessary reinforcement area is given by (Art. 6.2.3(3)):

Standard values of coefficients ν, νmax are built-in the program - these values can also be input by the user depending on the selected National annex.
