2.- Among these six yield lines patterns, the most likely one is the
cantilever pattern, rectangular shape.
The minimum Mp required to build the slab is Mp = 2q
3.- If q = 10 kN/m2, and the Mp is 100 kNm/m, as the required
Mp to build the slab is Mp = 2q = 20 kNm, the safety factor
would be 100/20 = 5
4.- If we build the slab with a cross section that can support up to
100 kNm, the total distributed load that can be supported is q =
Mp/2 = 50 kN/m2
If the slab weight is 7,5 kN/m2 is qlived = 50 – 7,5 = 42,5 kN/m2
