45. CHAPTER 10 PROBLEMS
(1) It is required to design the flat slab
roof shown in figure. For architectural
purposes, it is not allowed to use drop
panels or columns’ heads.
Fcu = 25 N/mm2. Fy = 360 N/mm2.
L.L. = 4 KN/m2. F.C. = 2 KN/m2.
Walls = 1.5 KN/m2. Floor height = 3.5 m
46. CHAPTER 10 PROBLEMS
(2) Check the safety against punching
failure of a corner column (0.4 x 0.4 m) in
a flat slab system without marginal beams
of a typical panel (6.5m x 6m). The total
ultimate load is 17 KN/m2, ts = 200 mm
and Fcu = 25 N/mm2.
