1. GEODESIC DOMES The only structure system that can be attributed to one man R. Buckminster Fuller. Geodesic domes are giant bubbles created from metal rods arranged into triangles.

2. Domes offered advantages never available before in architecture. Very light weight in relation to size and amazingly strong.

5. Suspension This structure is mostly associated with bridges. Developed in 19th century. Weight of the structure is suspended from steel cables that are attached to vertical pylons driven into the ground.

6. Reinforced Concrete Concrete: mixture of cement gravel and water, dating back to Roman Times. Concrete: Brittle and low tensile strength. Often seen in sidewalks and patios.

7. This problem was fixed in the 19th century when a method was developed for reinforcing the concrete by putting metal rods in the concrete.

9. Not only used as skeletons, but can be used as shell and form structures that are self sustaining.

10. Reinforced concrete is the sort of material that allows the builder to experiment and try new techniques. http://www.youtube.com/watch?v=FcpcIHBTfU8
