Roof slab design example.

Design example the layout of a floor slab is shown in figure 1 below. Let us take an example of a slab. Steel yield strength fy 40 ksi. Q the length and breadth of slab is 10 meter and 7 meter respectively.

Let the shorter span has provided the main rod and longer span has provided distribution rod. Numecal for rcc roof slab steel calculation. 2 thick brick tile. Plan view of a reinforced concrete pitched inclined slab.

Design the floor to satisfy ultimate and serviceability limit state requirements. 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. Roof slab forms the top cover for main vessel which is filled with concrete for the purpose of nuclear radiation shielding. Live load 40 psf figure 1.

The shorter span of one way slab is provided with the main reinforcement while the longer span is provided with the distribution reinforcement. Design the roof slab beam and column of house given in figure 1. Beside this the slab has following information for main bars length of on rod 7 meter diameter 12 mm. Concrete compressive strength fc 3 ksi.
