What defines the dimensions 'Length' and 'Width of Reinforcement' relating to the longitudinal reinforcement in RF-PUNCH Pro? Is the anchorage length included?

Answer

The RF-PUNCH Pro defines the required length of the longitudinal reinforcement or the width of reinforcement in the RF-PUNCH Pro 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
The following applies for the width of the longitudinal reinforcement:
  • 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)]
An anchorage length of the longitudinal reinforcement is not calculated by the add-on module and must additionally be taken into account by the user.
