 Definition : A dome is a element of architecture that
resembles the hollow upper half of the sphere.
 Dome is rounded vault made of either curved
segments or a shell of revolution , meaning an arch
rotated around its central axis.
 A masonary dome produces an thrust downward
and outward so domes can be divided into 2 kinds:
simple and compound , depending on the use.
 A dome can be supported by columns or piers that
transition to the dome through squinches or
pendentives.

 Early and indigenous domes
 the early domes were likely to be made from saplings, reeds
timbers and covered with thatch tuff or skins.
 Materials may have transmitted to ramed earth , mud bricks or
more durable adobes as result of local conditions.
 Roman and byzantine domes
 They are customarily hemispherical in shape on general and
monumental dome in particular.
 The dome of pantheon is the most important dome of roman
period Largest roman concrete dome.
 Morden period domes
 Morden period domes were made from many durable materials
and in many new styles and forms.
 New production techniques allowed iron, wood and many
different materials to use in dome construction..
 Unique glass domes springing straight from ground level were
used for green house.

A. Geodesic dome is a sphere or say partial spherical structure
based on a network of great circles on the surface of a
sphere.
B. The triangular elements formed by network makes it rigid
and also helps in distributing stress of the structure.
C. Its main part is the joints that completes the whole sphere.
D. Geo means earth and desic means divided

 The Panelized Technique Allows The Builder To Attach The
Plywood Skin To The Triangles While Safely Working On The
Ground Or In A Comfortable Shop Out Of The Weather. This
Method Does Not Require Expensive Steel Hubs….
 Holes Are Drilled Through The Members At Precise Locations
And Steel Bolts Then Connect The Triangles To Form The Dome.
These Members Are Often 2x4's Or 2x6's, Which Allow For
More Insulation To Fit Within The Triangle

 Generally For Such Domes They Start With A Steel Framework
Dome, Wrapped With Chicken Wire And Wire Screen For
Reinforcement. The Chicken Wire And Screen Is Tied To The
Framework With Wire Ties.
 A Coat Of Material Is Then Sprayed Or Molded Onto The Frame.
Tests Should Be Performed With Small Squares To Achieve The
Correct Consistency Of Concrete Or Plastic.
 Generally, Several Coats Are Necessary On The Inside And

 It is a dome having the form of a segment of a sphere,
with the center well below the springing line; a shallow
dome.
 A dome that is very shallow; its radius of curvature of
the dome is very large compared with its rise.
 They exist entirely in compression so that it can be
built much thinnoer than other dome shapes without
becoming unstable.
 The trade-off between the proportionately increased
horizontal thrust at their abutments and their
decreased weight and quantity of materials may make
them more economical.
 They are more vulnerable to damage from movement
in their supports.

 A parabolic dome is a unique
structure in which bending
stress due to the uniformly
distributed load of its dead
load is zero.
 Hence it was widely used in
buildings in ancient
times,before the advent of
composite structure.
 However if a point load is
applied on the apex of a
parabolic dome,the bending
stress becomes infinite.
 Hence it is found in most
ancient structures,the apex of
the dome is stiffened or the
shape modified to avoid the

• In ancient Egypt brick vaulting was used ,chiefly for drains . The
Chaldeans and Assyrians used vaults for the same purpose but
seem also to have made architectural use of high domes and
barrel vaults.
• The Greeks made no use of vaults.
• Then Rome adopted this technique by using concrete as a
construction material so that no outer or external thrust or
buttresses need to be given. Thus vaults could be easily erected
over vast spaces ,producing impressive and complex thermo ,
amphitheatres , and basilicas .
• The tunnel vault spans between two walls ,like a continuous arch.
The cross , or groined , vault is formed by the intersection at right
angles of two barrel vaults , producing a surface that has arched
openings for its four sides and concentration of load at the four
corner points of the square or rectangle .
• the semicircular arch was universally employed in Romanesque
vaulting throughout Europe , and the roman cross vault was the
type used for covering square or rectangular compartments.

 STRENGTH
• The thrust generated against
wall which is its failure.
• Solution :
1. Walls should be thick(approx.
4m) and strong.
 2. Two or more vaults
should be kept parallel to
each other.
3. Intersection of two vaults
sholud be done at right angle
which is known as groin vault.
• Butressing should be done.
• Uses:

 GROIN VAULT
 Definition
 A Groin vault (also known as a double barrel vault) is produced by the
intersection at right angles of two barrel vault.
 Characteristics
 The word “groin” refers to the edge between the intersecting vaults.
 Sometime the arches of groin vaults are pointed instead of round.
 In comparison with a barrel vault, a groin vault provides good economies of
material and labour.
 The groin vault required great skills in cutting stone to from a neat arris.
 Difficult to construct neatly because of the geometry of cross groins.
 The construction of groin vault can be understood most simply by
visualizing two barrel vault section at right angles merging to form a
squarish unit.

 Definition
 The intersection of two or three barrel vaults produces a rib vault or ribbed
vault .
 Characteristics
 when they are edged with an armature of piped masonry often carved
in decorative patterns compare groin vault an older from of vault
construction.
 While the mechanics of the weight of a groin vault and its
transmission outwards to the supporting pillars remained as it had
been the new use of rib vaults demonstrates the skill of the masons
and the grandeu of the new ideas circulating at the introduction of
gothic architecture in the end of the eleventh century.
 This technique was new in the leta eleventh century for example in
the roof of the lchoir side aisles at Durham cathedral.
 Ancestors of the gothic rib vault in the Romanesque vault can be
found at caen and durham both sites of early gothic constructions and
elsewhere.
 Some ribbed vaults even have six section in each bay.
