Arch
The Arch and Dome Ideas are
presented, including their types. Designing with arch and dome design software

spans an open space, and designed to hold the weight above it.
Its development punctuated
the history of architecture by enabling builders to make larger openings and
distribute weight more efficiently.
The arch is a symbol of
strength because its shape makes it easier to transfer loads from the top
downward along the whole span which in turn is partially what makes this type
so strong compared with other arches without straight lines or corners.
On the other hand, without
the arch, many architectural masterpieces, such as bridges, cathedrals and
aqueducts for cities, would not have been possible.
Types of Arches
1. Roman Arch: The Roman
arch, also called the "round" arch, is both one of the earliest and
most widely used kinds. It forms a semicircle such that it often makes up the
bridge or aqueduct spans seen in Western Roman architecture. This shape is
strong because its smooth curvature spreads weight evenly across an entire
structure.
2. Pointed Arch: In this
type of arch, the top instead shakes off the weight a little more than usual.
This lets be built towering buildings like Gothic cathedrals that might
otherwise tend to collapse under their own weight. The pointed arch made
possible greater height; greater window area was another of its distinguishing
features in medieval building.
3. Segmental Arch: A
segmental arch is one that curves less than half of a circle and is known as a
segment. This type of arch is seen in modern doorways and bridges because it
has to be unnoticable and gently swinging: This makes segmental arch a sturdy
way to transfer load without making too deep an impression on our eyes when we
view from below!
4. Catenary Arch: This arch
is the shape of a hanging chain or cable called catenary curve. It is seen in
modern structures because it bears heavy loads and has aesthetic precision.
Uses for the catenary arch include bridges, roofs and even (in some modern art
installations) itself.
Dome
The dome is a hemispherical
structure, used often for spanning large spaces. It is one of history's oldest
and also most exquisite types of design, eliminating the need for support
columns in vast interiors.
Domes have appeared in some
of the most famous buildings in the world, including sacred temples and
government-civic buildings and public spaces.
Kinds of Domes
1) The Spherical Dome: The
spherical dome is a perfectly formed round body that offers good weight
distribution and a stable structure. It can be found in many places as a house
of worship, relatively simple civic building or even an art museum.
2) The Geodesic Dome:
Popularized by architect Buckminster Fuller, the geodesic dome is composed of a
network of triangles that form a roughly spherical shape. This design requires
only minimal materials yet delivers optimum strength. Geodesic domes are used
for all sorts of applications: horticultural exhibition spaces, temporary
shelters and even homes because they provide natural energy which can be
concealed below ground.
3) The Onion Dome: This
dome has a very distinctive shape, similar to the Russian and Eastern European
style of onion-shaped church domes. With its rising lines in the middle which
then converge and taper towards the top for added beauty, the onion dome is
extremely attractive.
4) Barrel Vault: A barrel vault is really a series of arches, an endless row on an arched foundation. It is only in the sense that they share same strength and stability achieved by vaults that treat (although not in form) really a dome.
