Considering Shift Rule and Anchorage Length in Provided Reinforcement

Is the shift rule or the anchorage length of the longitudinal reinforcement already taken into account in the reinforcement proposal?

Answer:

In RF‑CONCRETE Members (RFEM) or CONCRETE (RSTAB), the shift rule is taken into account by default when determining the reinforcement.

You can see the difference between the required reinforcement with and without the shift rule when displaying the results in the Results navigator:

A_{s,-z (top)}
A_{s,+z (bottom)}
A_{s,-z (top),req.}
A_{s,+z (bottom),req.}

In A_{s,-z (top),req.} and A_{s,+z (bottom),req.}, the shift rule is included. See also Image 01.

1 Distribution of Required Reinforcement

In the case of the reinforcement proposal in RF‑CONCRETE Members or CONCRETE, the anchorage length for a "straight bar" is taken into account by default. You can find the setting for this in Window 1.6. See Image 02.

2 Selecting Anchorage Type for Longitudinal Reinforcement

The anchorage length is determined from A_{s,-z (top),req.} and A_{s,+z (bottom),req.}. So the shift rule is also included here.
