“Construction of slab-column-connections
in semi-precast slabs”

Semi-precast slabs become more and more important as flat slabs due to the high degree of prefabrication. Their structural design is important in terms of safety owing to the high shear stress and moment action in the area of the slab-column-connection. The distance between precast slabs and column varies in practice. Based on the minimum joint width of 4 cm between the precast slabs, as required by individual technical approvals, the distance chosen between precast slab and column edge partially is of this width. The advantage of such a construction is the fact that dimensional and positional...
