Answer:
RF‑PUNCH Pro defines the required length of the longitudinal reinforcement or the width of the reinforcement as follows.
For the length of the longitudinal reinforcement:
- Case 1 – No punching shear reinforcement required:
Length of longitudinal reinforcement = 2*lw,crit + column width
- Case 2 – Punching shear reinforcement required:
Length of longitudinal reinforcement = 2*lw,out + column width
For the width of the longitudinal reinforcement, the following applies:
- Case 1 – No punching shear reinforcement required:
Width of reinforcement = 6*d + column width
- Case 2 – Punching shear reinforcement required:
Width of reinforcement = maximum value from [(6*d + column width) OR (2*lw,out + column width)]
The add-on module does not calculate the anchorage length of the longitudinal reinforcement, and you have to take it into account additionally.
