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:
