Application width of concentrated load on slab
The application width t of concentrated load P onto the middle level of the slab is expressed as: t = b0 + 2×(s+hs/2) = b0 + 2×s + hs, where s is the covering thickness. Thickness s should not be taken into consideration, when the concentrated load is applied directly onto the concrete‘s surface, e.g. in the case of brick masonry.
Distribution width of concentrated load
One-way slab bearing concentrated load The distribution width of the concentrated load is a function of the support types of the slab (fix, simple, free) and the distance x between the center of mass and the supports. The following table gives the distribution width of partial uniform load for every type of support.
Distribution width of partial uniform load
bm,f = ty + 2.5×x×(1-x/l) tx,max = l, ty,max = 0.8l

Fixed-end slab
bm,vL = ty + 0.5×x tx,max = l, ty,max = 0.8l bm,vR = ty + 0.5×(lx) tx,max = l, ty,max = 0.8l
bm,vL=0.37+0.5×1.5 bm,f=0.37+2.5×1.5×(1=1.12 m Example 1 0.375)=2.71 m bm,vR=0.37+0.5×2.5 =1.62 m bm,vL=0.37+0.5×2.0 bm,f=0.37+2.5×2.0×(1=1.37 m Example 2 0.5)=2.87 m bm,vR=0.37+0.5×2.0 =1.37 m Left: για 0.2
