Design of shear reinforcement for plates
Design of shear reinforcement for plates
The program allows determination of the required amount of shear reinforcement form by stirrups and hooks, respectively.
First, the program computes the ultimate shear strength in a given section – the shear force transmitted by concrete Vc and the maximum allowable shear force Vmax.
where:
for cross-sections with height smaller than 200mm
vc is computed acording to following formulas for cross-sections with height greater than 400mm, intermediate values are obtained using linear interpolation method.
where ρw is degree of reinforcement and fc' is limited to value 50MPa.
If the ultimate shear strength of concrete is exceeded, the ultimate shear strength Vmax is checked.
As for stirrups the necessary reinforcement area is given by:
As for hooks the necessary reinforcement area is given by:
