Markus Baumgärtel Design RFEM RF-CONCRETE

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

One could also measure the wall ends (at the transition to the ceilings) with RF-BETON surfaces and as a result obtain a required reinforcement quantity in [cm² / m].
Alternatively, one could also insert result bars into the areas with the relevant tensile force in the walls and integrate the area intersection variables resulting in these areas into stump sizes. In this case, attention should be paid to a sufficient FE mesh compaction in the area for which the surface intersection sizes are to be integrated into stub sizes.

Subsequently, these result bars (with the stump sizes that actually come from the areas) in RF-CONCRETE bars measured (in this case, for a tensile force).
This gives the tensile reinforcement in [cm²] required for a defined area.
