2. What is Geodesic Dome?
A Geodesic Dome is a hemispherical thin-
shell structure (lattice-shell) based on a
Geodesic Polyhedron. The triangular
elements of the Dome are rigid in
structure. These elements distribute the
stress throughout the structure, making
the dome able to withstand heavy loads.
3. Where is Geodesic Dome used?
These domes can withstand hurricanes,
earthquakes & fires better than rectangle-
based structures. They are used for
military Radar Systems, Churches,
Auditoriums & for special Events in which
temporary, inexpensive & strong shelters
are needed.
4. Objective:
Build a model of Geodesic Dome using newspaper tubes.
Materials used:
Newspaper, scissor, glue, rolling stick, cello tape.
Description of newspaper tubes:
Long tubes (14 cm) - 35 nos.
Short tubes (12.5 cm) - 30 nos.
Project - Geodesic Dome
5. Project - Geodesic Dome
Procedure:
• Connect 10 long tubes using cello tape to form base.
• Form triangles using long & short tubes (10 nos. each).
• Connect vertices of the triangles using 10 short tubes.
• Form sets of 5 adjoint triangles (each set includes 2 long tubes & 1 short
tube in the middle as common side).
• Connect vertices of these triangles using 5 short tubes.
• Finally connect 5 long tubes from the 5 vertex points to meet at a single
point at the peak of the dome.
6. Project - Geodesic Dome
Result:
The Geodesic Dome results in a very strong
structure that can withstand the load of much
heavier objects (For eg: Thick Textbook in this case)
as shown below.
