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 M.

The permissible moment for a given area of reinforcements As reads:

The program further checks whether the location of neutral axis x is less than the limit location of neutral axis xmax given by:

- for steel Fe 250

- for steel Fe 400

- for steel Fe 500

The computed degree of reinforcement is checked using the following expressions:

Shear

First, the program computes the ultimate shear strength of concrete Vuc.

where: τc is determined according to table 19 standard IS 456 : 2000.

If the ultimate shear strength of concrete is exceeded, the ultimate shear strength Vuc,max is checked.

where: τc,max is determined according to table 20 standard IS 456 : 2000.

Next, the necessary reinforcement area is given by:

where:
