Design of Shear Reinforcement for Slabs

The program allows determination of the required amount of shear reinforcement form by stirrups and bends, 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.

As for stirrups the necessary reinforcement area is given by:

As for bends the necessary reinforcement area is given by:
