Load transfer in cantilevered balconies requires Schöck Isokorb® to transfer moment and transverse forces into the connecting ceiling. Transfer of the bending moment is ensured by the tension rod (top) and the pressure bearing (bottom). A bending moment may be divided into a force couple, which has the same value but points in different directions. The moment is calculated from force F multiplied with the inner arm of lever e.
M = F x e
This is how the moment from the balcony slab is divided and transferred into the ceiling panel by tension in the upper tension rod and pressure in the pressure bearing. The higher Schöck Isokorb® is, the higher the inner lever arm, the higher the bending moment that can be transferred. The maximum (actually minimum) possible moment that can be transferred is called mRd.
