The amount of reinforcement and final shape in several of the bails must be determined in each case. This can be done acc. procedures given in Memo. Concrete Quality C35 and beam dimension: W × H = 300 × 450 is used in the example. This beam dimension corresponds approximately to minimum beam cross-section in order to exploit the unit’s capacity.
For more info reinforcement in beam see memo 522 a-e.
The figure illustrates the recommended principal reinforcement in the column. A portion of the vertical force will spread into the column via the reinforcement bar welded to the bottom of the steel plate, while the remaining force will go into the column via distributed concrete stress underneath the steel plate. Splitting forces will occur due to horizontal spreading of the forces into the cross section of the column.

Beam cross-section and secondary beam suspension point in the longitudinal direction of the main beam will vary. This may produce different varieties of force once the main beam and the exact load bearing behavior must be assessed in each case. This will vary depending on the geometry of the compound and may arise at the transmission which is not covered by example in the calculations.
