Types
Types of Curved Roofs : 1. Shell Roof and 2. Dome Roof.
CURVED ROOFS
Curved
Roof is the modification of pitched roof. As the name implies, the roof surface
is curved in one or more directions. Curved roofs are used for covering large
area.
Types
of Curved Roofs
1.
Shell Roof and 2. Dome Roof.
1. SHELL ROOF
Shell
Roof is used for covering big structures. As the shell section needed is very
thin, a lot of material is saved. Dead load is very much less. The shell acts
as a membrane free from high bending stresses.
Two
types of Shell Roofs are:
(a)
North-light Shell Roof (Fig. 16)
See
Fig. 16. It contains Shell Roof, Glazing, Edge Beam and Valley Beam.
Uses:
North-light shell roof is used where sunlight is essential. For big buildings
such as industrial buildings, assembly halls, libraries, etc., R.C.C. shells
are used. In small buildings, shell roofs made of either brick or plain
concrete is used.
(b)
Barrel Vault Shell Roof (Fig. 17)
It
has a long multiple Cylindrical Shell with Edge Beams. It is used where
sunlight is not a must.
2. DOME ROOF
A
Dome is a semi-spherical or semi-elliptical shaped structure. It is used where
the building is circular or hexagonal in plan. It is supported on circular or
regular polygon shaped walls. It is a very thin structure. It is constructed of
brick or stone or concrete.
Dome
is used where architectural treatment is needed. This type of roof is most
suitable for Monuments and Places of worship.
