Rcc sloped roof slab design pdf.

Domes concrete shell roofs 2. The construction of the original building consisted of a reinforced concrete frame with cast in situ trough floors. Pdf chapter 2 structural design of rcc building. Some designers recommend a monolithic slab poured over the top of the beams.

Long cylindrical shell ijert a roof slab consisting of a plane surfaces triangular in shape and bounded on each side by a sloping ridge forming the intersection of adjacent. Others design the final roof finish to be applied over the foam. An extra floor was required to be constructed which involved converting the original roof slab to a floor slab thereby increasing the live load capacity to 3 kn m 2. Sloping slabs under gravity load would be subjected to bending and axial thrust.

But bermudez says the design is relatively simple to create using finite element software. Design the roof slab beam and column of house given in figure 1. Waffle slab grid slab 5. According to the 1995 aci code all two way reinforced concrete slab systems including edge supported slabs flat slabs and flat plates are to be analyzed and.

Folded plate design structurally these roofs are folded plates so they require an engineer ing design. The design of the upper storey extension was a lightweight strut. Pockets running parallel to the ridgeline are usually cut into the foam on site. Foam decking creates a series of beam pockets which are filled with reinforced concrete.

Circular slab non planer roof slab. Steel yield strength fy 40 ksi. Based on the boundary condition you can determine the axial thrust and the bending moment. If the problem is statically determinate the equilibrium equations would.

The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12.
