6.3.2 Slab loads The slab load (kN/m2) eonsists of a dead load
g. and a live load Ps' The dead load on the slab consists ofits own
weight and the weight ofthe flooring above. Dead load of the slab
gs is calculated from:
g, =t, x re + Flooring
.......................................... (6.3) The floor covering
(jlooring) is usually taken from 1.5 to 2.5 kN/m2 depending on the
used materials. The live loads Ps on the slab depend on the usage
of the structure as given in Chapter l.
In cases where the slab is supported on aH four sides and the
ratio of length to width is larger than 2 (Fig. 6.3), the short
direction ofthe slab is stiffer than the long one. In 8uch a case,
the slab carries the load in its short direction and aets as a
one-way slab. Accordingly, only the beams (AB and CD) of long spans
support the loads from the slab.
