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. Model 1 has a slope of 36 degree. But bermudez says the design is relatively simple to create using finite element software. So i ve made three models in staad to study about the behavior of the building for different slope angles.

Roof diaphragm design shearwall design continuous footing design. Pdf chapter 2 structural design of rcc building. The slab should be strong enough to bear the required load according to design. Reinforced concrete sloped roof slab overhang detail cantilever overhang inclined slab supported from a reinforced concrete beam at the roof edge.

Now that its projected on a horizontal surface with an amplified load follow the same procedures for the horizontal slab design.

This permits concrete place ment without the use of top forms. 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. 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. They have asked me to suggest the pitch height such that it is economical and also safe in design.

Folded plate design structurally these roofs are folded plates so they require an engineer ing design. Triangular panels of pyramidal slabs make an angle with vertical axis. The full form of rcc is reinforced concrete cement. 2003 international building code.
