Rcc Sloped Roof Slab Design

Here is a detailed article with all the information regarding procedure of rcc slab roof laying.

Rcc sloped roof slab design. This permits concrete place ment without the use of top forms. Foam decking creates a series of beam pockets which are filled with reinforced concrete. I have given an example for the calculation of the quantity steel rod in slab below. How to calculate slop of rcc slab.

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. Design of structures dos online 1 459 348 views. Where reinforcement is called a steel rod. Pockets running parallel to the ridgeline are usually cut into the foam on site.

Now that its projected on a horizontal surface with an amplified load follow the same procedures for the horizontal slab design. The slab should be provided steel bars to withheld tensile force so this slab is called the rcc slab. The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12. Others design the final roof finish to be applied over the foam.

Tips for laying rcc slab roof on 12 09 2014 9091 view s 3 comment s rcc slab laying is one of major step in any type of construction so it is mandatory to know all the points related to laying rcc slab. Some designers recommend a monolithic slab poured over the top of the beams. But bermudez says the design is relatively simple to create using finite element software. Folded plate design structurally these roofs are folded plates so they require an engineer ing design.

The full form of rcc is reinforced concrete cement. The slab should be strong enough to bear the required load according to design. 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.
