Stirrup

Stirrups are used to absorb the shear and torsional forces in concrete components.

Dialog Box "New Stirrup"

The stirrup number is assigned automatically, but can be changed. The order is irrelevant for the numbering. It does not have to be continuous, either; gaps in the numbering are allowed.

Cover Points Nos.

Stirrups can only be placed at cover points. The cover points are points of the "On line" type on the cover line. You can also create additional cover points on the cover line and use them for the stirrup arrangement.

It is possible to define open and closed stirrups. If the stirrups are closed, the start and end cover points are connected to each other.

Material

In the list of already created materials, you can select a material for the stirrup, edit it, or define a new one. Only the "reinforcing steel" materials are allowed.

Parameters

The parameters of a stirrup diameter d_{s, st}, a stirrup diameter of curvature d_{br, st}, and a mandrel diameter k are interdependent. The relation is described in the following equation:

d_br,st = k · d_s,st
