Rcc sloped roof slab design pdf.

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

The design of the upper storey extension was a lightweight strut. Axial forces from snow loads and roof live loads should usually not be considered simultaneously with an extreme wind load because they are mutually exclusive on residential sloped roofs. Sloping slabs under gravity load would be subjected to bending and axial thrust. The slab should be strong enough to bear the required load according to design.

Pdf chapter 2 structural design of rcc building. The construction of the original building consisted of a reinforced concrete frame with cast in situ trough floors. Domes concrete shell roofs 2. Circular slab non planer roof slab.

The full form of rcc is reinforced concrete cement. 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 slab should be provided steel bars to withheld tensile force so this slab is called the rcc slab. Steel yield strength fy 40 ksi.

Waffle slab grid slab 5. Concrete compressive strength fc 3 ksi. Simply the slab in which steel bars are used is known as rcc slab. Pyramidal roof slab 4.
