Rcc Sloped Roof Slab Design

Pockets running parallel to the ridgeline are usually cut into the foam on site.

Rcc sloped roof slab design.

The slab should be provided steel bars to withheld tensile force so this slab is called the rcc slab. Some designers recommend a monolithic slab poured over the top of the beams. Others design the final roof finish to be applied over the foam. The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12.

Foam decking creates a series of beam pockets which are filled with reinforced concrete. Folded plate design structurally these roofs are folded plates so they require an engineer ing design. The slab should be strong enough to bear the required load according to design. Design it like a stair i e load the inclined slab and then project the inclined load to a horizonatal load by multiplying it with the inclined length an then dividing it by the horizontal length.

Rcc slab roof design example structural concrete roof or slab is made waterproof by applying stabilised bitumen sheets the floor is first cleaned and then some bitumen is sprinkled over the surface and then bitumen stabilised sheets are rolled over the surface and joined with other at edges by applying heat through gas torch. This permits concrete place ment without the use of top forms. The full form of rcc is reinforced concrete cement. Triangular panels of pyramidal slabs make an angle with vertical axis.

But bermudez says the design is relatively simple to create using finite element software. A roof slab consisting of a plane surface triangular in shape and bounded on each side by a sloping ridge forming the intersection of adjacent planes and culminating in a common vertex is known as pyramidal roof. I have given an example for the calculation of the quantity steel rod in slab below. Where reinforcement is called a steel rod.
