Is the offset already taken into account for the provided reinforcement, or is the length of the anchorage anchored to the longitudinal reinforcement?

Answer

In RF-CONCRETE Members (RFEM) or CONCRETE (RSTAB), the offset is considered by default when determining the provided reinforcement.

The difference between required reinforcement with and without offset is displayed when you open the Results navigator window:
- A s, -z (top)
- A s, + z (bottom)
- A s, -z (top), comp.
- A s, + z (bottom), comp.
display results.

In A s, -z (top), comp. and A s, + z (bottom), comp. the offset is included.
See Figure 1.

For the provided reinforcement in RF-CONCRETE Members or CONCRETE, the program considers the anchorage length for "straight" iron by default. The input can be found in the input window 1.6. See Figure 2.

The anchoring length becomes from A s, -z (top), comp. and A s, + z (bottom), comp. determines. Thus, the offset is also included here.
