Documentation of Applied Shear Force for Shear Design

For uniformly distributed loading according to EN 1992‑1‑1 (Eurocode 2), the design section for the shear reinforcement can be placed at the distance d from the front edge of the support. Thus for the shear reinforcement, the applied shear force is reduced to VEd,red. To analyze the maximum design shear resistance VRd,max, however, the total shear force is applied.

To achieve complete documentation of the applied shear forces, the total shear force VEd as well as the reduced shear force VEd,red are displayed in the design details or graphically.

In the design details of Window 3.3, the shear resistance ratios of the reinforced cross-section are listed below:

  • VEd, red/VRd, c
  • VEd, red/VRd, s
  • VEd/VRd, max

VEd... Shear force effect
VEd, red... Reduced shear force
VRd, c... Shear force resistance without shear reinforcement
VRd, s... Shear force resistance with shear reinforcement
VRd, max... Maximum shear force resistance of the concrete compression strut

You can also display the utilization ratios graphically as a result diagram and add it to the documentation.
