Verification of rectangular RC cross-section under M, V

The cross-section is rectangular, reinforced on one side and loaded by the bending moment M_Ed.

The permissible moment for a given area of reinforcements A_s reads (Art. 6.1, Art. 3.1.7(3)):

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

Standard values of coefficients ρ_min, ρ_max are built-in the program – these values can also be inputted by the user depending on the selected National annex.

Shear

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

where:

If the ultimate shear strength of concrete is exceeded, the maximum ultimate shear strength V_Rd,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, ν_max are built-in the program – these values can also be inputted by the user depending on the selected National annex.
