Foam decking creates a series of beam pockets which are filled with reinforced concrete.
Rcc sloped roof slab design.
The full form of rcc is reinforced concrete cement.
But bermudez says the design is relatively simple to create using finite element software.
The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12.
Pockets running parallel to the ridgeline are usually cut into the foam on site.
Folded plate design structurally these roofs are folded plates so they require an engineer ing design.
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.
Here is a detailed article with all the information regarding procedure of rcc slab roof laying.
The slab should be provided steel bars to withheld tensile force so this slab is called the rcc slab.
Others design the final roof finish to be applied over the foam.
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.
The slab should be strong enough to bear the required load according to design.
Now that its projected on a horizontal surface with an amplified load follow the same procedures for the horizontal slab design.
Triangular panels of pyramidal slabs make an angle with vertical axis.
Where reinforcement is called a steel rod.
Some designers recommend a monolithic slab poured over the top of the beams.
I have given an example for the calculation of the quantity steel rod in slab below.
