The document discusses geodesic domes and folded plate structures. It provides background on geodesic domes, noting they are made of thin shells of triangles arranged in a space frame to create a stable structure. It describes the history and development of geodesic domes, and the planning, assembly, materials, and advantages/disadvantages of these structures. It then discusses folded plate structures, how they distribute loads, different types based on shape and materials, and provides examples like Notre Dame de Royan church. It concludes with advantages like longer spans with thin materials, and disadvantages like needing accurate formwork.

1. GEODESIC DOME

2. INTRODUCTION
•Thin shelled
•Arrangements of triangles
•Triangles - stress
•Space frame makes the dome
stabled.
•Triangles - hexagons and
pentagons to eventually form a
dome.

3. HISTORY OF
GEODESIC DOME
•Walter Bauersfelt, 1919,
Germany - first model was half
a sphere
•Architect R. Buckminster Fuller
- designed it to be affordable
and efficient. Geodesic dome.
•Milan triennale

5. PLANNING THE CONSTRUCTION
•Size and amount of triangles -
calculations to form the dome
•Struts: - framework for the dome
•Material selection
•Finalizing the structure

8. STRUT PREPARATION

9. DOME ASSEMBLY

10. DOME ASSEMBLY

11. DOME ASSEMBLY

12. MATERIALS

14. ADVANTAGES
•Stable and easy construction
•Even distribution of weight
•Ideal for almost any type of spaces
•Aerodynamic shape
•Reduced interior temperature and heat
gain and enables uniform air flow.
•Less materials are required, hence
lowering costs.
•Very quick and easy assembly
•Vast usage

15. DISADVANTAGES
•Unusable space
•Custom windows and
doors
•The building’s permit
•The financing and
rescale
•Very skilled labors.
•Separation between the
materials

17. Folded
Plate
Structure

18. Engineer Eugene Freyssinet performed the first roof with the
folded structure in 1923 as an aircraft hangar at Orly
Airport in Paris

19. Folding Systems in Nature
The Principle of Folding
THE CONCEPT OF STIFFNESS GENERATION

20. STRUCTURAL BEHAVIOR
OF FOLDING
Load Distribution process :
oExternal forces are transferred
to the shorter edge
oReaction as an axial force
oForces transferred to the
bearings.

21. TYPES OF FOLDED STRUCTURE
Based on geometric shape folded
structures can be divided into:
oFolded plate surfaces structures
oFolded plate frames structures
oSpatial folded plate structures

22. TYPES OF FOLDED STRUCTURE
Classification of folded
structures based on the
material they are made of:
oFolded structures made of
reinforced concrete
oMetal folded structures
oFolded structures of wood
oFolded structures of glass
oFolded structures of
plastic materials
oFolded constructions
made in combination of
different materials

23. Notre-Dame de Royan
Church in Royan, France
Miami Marine Stadium

24. Mezzanine ceiling
called "Kielsteg"
Metal Sheet Pile Shoring
for Foundation

25. ADVANTAGES:
o Span 30m; shell thickness = 60 mm only.
o Concrete
o Longer span
o Flat shapes and arched shapes.
o Aesthetics
DISADVANTAGES:
o Shuttering is difficult.
o Greater accuracy in formwork is required.
o Good labor and supervision necessary.
o Rise of roof may be a disadvantage.
