Steel-Frame and Ferroconcrete
Explain cantilever construction. Is the structure below an example of cantilever construction? Why/why not?
Cantilever construction features a horizontal beam that extends past its vertical support. This structure is an example of cantilever construction. You can see the horizontal beams of the roof and base extend past the vertical supports, creating a unique design.
Define the terms, domino and construction. What is domino construction?
Domino is the vertical steel support and horizontal slab of reinforced concrete which is connected by stairways. Construction is the act of building or assembling an infrastructure. Therefore domino construction is the building of a structure using a vertical steel support and horizontal slab of reinforced concrete which is connected by stairways
What is ferroconcrete? Where does the term come from? What is another common term for ferroconcrete?
Ferroconcrete is also called reinforced concrete. The term comes from the Latin word for iron, which is "ferro". It uses iron bars, called rebar, to reinforce it.
What is a steel frame? What two parts make up a steel frame?
A skeletal frame constructed in a regular pattern to support the floors, roof, or walls. A steel frame is made up of vertical steel columns and horizontal I-beams.
How is a suspension construction made? Where is it most commonly used?
A type of construction where the main load-bearing elements are hung from suspension cables which are suspended from vertical supports anchored into the ground or a riverbed. This type of construction is most commonly in bridge building.
List what both A and B are? What is the whole structure?
A) Horizontal I-beams B) Vertical steel columns This is a steel frame structure
Examine the two photograph pieces of architecture above. What building technique or material was used to create each? In your opinion, did the architect use the best technique? Why/why not? If you would have chosen another technique, what would you have chosen?
A) This is an example of suspension construction. B) This is an example of a construction which used ferroconcrete. Opinions will vary, but should address the question directly and include justification.
What are the benefits to skyscrapers verses other types of construction in the past?
Skyscrapers are cost effective and minimize space. They are also seen as examples of a nation or company's power and strength.
Name and describe the type of structure shown in this sketch. What development(s) made this structure, and others similar, possible?
This is a skyscraper. A skyscraper is a tall, multi-storied building. It was made possible by the development of steel frame construction using I-beams, which have an I- or H- shaped cross-section.
What is the name of this skyscraper? Why is it important? What do you notice about the design of this building? Who designed this structure?
This skyscraper is the Wainwright building. It is one of the earliest examples of a skyscraper. This structure is nine stories tall. Its corners are uninterrupted and the vertical lines created by the windows emphasize the height of the building to the viewer. This structure was designed by Louis Sullivan.
