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:
