Roof Slab Design Example

Slabs s1 and s2 to be designed.

Roof slab design example.

Q the length and breadth of slab is 10 meter and 7 meter respectively. Design the floor to satisfy ultimate and serviceability limit state requirements. Beside this the slab has following information for main bars length of on rod 7 meter diameter 12 mm. 2 thick brick tile.

Slab reinforcement cantilever reinforcement slab thickness roof apex reinforcement example of a 1. Some of the prominent examples of the one way slabs are the cantilever slabs chajjas and verandahs. Design the roof slab beam and column of house given in figure 1. Plan view of a reinforced concrete pitched inclined slab.

Live load 40 psf figure 1. Concrete compressive strength fc 3 ksi. Roof slab forms the top cover for main vessel which is filled with concrete for the purpose of nuclear radiation shielding. Steel yield strength fy 40 ksi.

One method of overcoming this problem is to use ribbed slabs which are suitable for longer spans supporting light loading as in residential or commercial buildings. Design example the layout of a floor slab is shown in figure 1 below. Numecal for rcc roof slab steel calculation. Let the shorter span has provided the main rod and longer span has provided distribution rod.
