Abstract (en)
[origin: WO2011034420A1] Hollow core slab (1) comprising a top flange (5) and a bottom flange (6), a plurality of voids (3) and webs (4) between said voids and extending between said bottom and top flange. The hollow core slab is provided with one or more constructive elements for reducing the shear and/or bending force in the webs and/or for increasing the shear and/or bending resistance or capacity of the webs. Such constructive elements may comprise e.g. non-vertical webs (11), expansion joints (12), non-homogeneous material distribution (13) in the slab, small outer cores (14), preferably positioned at the side of the top flange, wide outer webs and/or absence of outer cores, bottom corner not significantly rounded off (16), vertical outer edges (17), reinforcement means (18) in the bottom flange, reinforcement means (19) in at least part of the webs.
