Calculation examples showing the loss in shear resistance

Design of precast floors with integrated building services –


Using reinforced concrete floors as space for building services becomes more and more common in practice. Conduits are built in the concrete cross-section being used for ventilation systems, electrical installations, or for using the concrete floors even as air-conditioned floor slabs. In comparison to suspended ceilings for covering installations, the reduction in the construction height and consequently the enclosed space is a decisive advantage here.

The weakening of the reinforced concrete floor slabs as a result of the conduits was only taken into consideration in individual...
