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 Qbu and the maximum allowable shear force Qmax.
where: | for: | h ≥ 0.3m | is: κq = 1.25 |
for: | h > 0.15m | je κq = 1.50 | |
for: | h < 0.15m | je κq = 1.60 |
As for stirrups, the necessary reinforcement area is given by:
As for bends the necessary reinforcement area is given by:
where:
The magnitude of c is bounded by the following expression:
