What is the best way to determine pull bars at wall ends (stiffening loads)?

Answer

You can design the wall ends (at the transition to the ceilings) in RF-CONCRETE Surfaces. As a result, you obtain the amount of required reinforcement in [cm²/m].

As an alternative, you can insert result beams into the areas with the governing tension force in the walls and thus integrate resulting surface internal forces into member internal forces in these areas. In this case, it is necessary to pay attention to a sufficient FE mesh refinement in the integration area. This procedure is also described in the technical article of our Knowledge Base, which you can find under Links below.

Afterwards, you can design the result beams with the member internal forces, which basically come from the surfaces, in RF-CONCRETE Members (for a tension force in this case). Thus, you obtain the required tension reinforcement in [cm²] for a defined area.

The result evaluation corresponds approximately to the theory of wall-like beams. This article is described in detail in the technical article " Design of Wall-Like Beams in RFEM ".
