This permits concrete place ment without the use of top forms. Others design the final roof finish to be applied over the foam. 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. Waffle slab grid slab 5.

Foam decking creates a series of beam pockets which are filled with reinforced concrete. 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. 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.

The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12. Based on the boundary condition you can determine the axial thrust and the bending moment. Sloping slabs under gravity load would be subjected to bending and axial thrust. Domes concrete shell roofs 2.

Pockets running parallel to the ridgeline are usually cut into the foam on site. Steel yield strength fy 40 ksi.

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

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. Pyramidal roof slab 4. Concrete compressive strength fc 3 ksi. The construction of the original building consisted of a reinforced concrete frame with cast in situ trough floors.

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