Rcc Sloped Roof Slab Design Pdf

Based on the boundary condition you can determine the axial thrust and the bending moment.

Rcc sloped roof slab design pdf.

The design of the upper storey extension was a lightweight strut. But bermudez says the design is relatively simple to create using finite element software. Sloping slabs under gravity load would be subjected to bending and axial thrust. Pockets running parallel to the ridgeline are usually cut into the foam on site.

The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12. Concrete compressive strength fc 3 ksi. The construction of the original building consisted of a reinforced concrete frame with cast in situ trough floors. 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. If the problem is statically determinate the equilibrium equations would. Steel yield strength fy 40 ksi. Domes concrete shell roofs 2.

Waffle slab grid slab 5. Design of structures dos online 1 459 348 views 0 41 construction sloping roof using mixer truck latest technologies building sloping concrete roof duration. Folded plate design structurally these roofs are folded plates so they require an engineer ing design. 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.

Design the roof slab beam and column of house given in figure 1. 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. Circular slab non planer roof slab. 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.

Some designers recommend a monolithic slab poured over the top of the beams.
