  1. Structural Components When you look at buildings, you see many of the same features We call these STRUCTURAL COMPONENTS They can: add strength AND be aesthetically pleasing

  2. The Hockey Hall of Fame - Toronto • Structural components can be used alone or in combination

  3. Beams – Strengthening Structures • Beams – A flat structure that is supported at each end; if • too much weight is put on a beam, it will bend or • even break in the middle • How to Strengthen Beams: • Change the material (wood, stone, concrete, steel etc) • Change its form (the type of beam) • Add Corrugation (folding the beam) • Add rebar (steel reinforcing rods)

  4. I Beams – Changing the Form I-Beam – its shape gives it strength. • They have less weight than solid beams of the same length • Because they have less of their own weight to support, they can support larger loads • Often used in building construction; structural support in ceilings and floors • Sometimes called I-joists

  5. Corrugation (Think Folding) When a sheet of metal or cardboard is shaped into a series of pleats, or triangles it is called corrugated metal or corrugated cardboard • Stronger than a flat sheet of material

  6. Real Life Examples

  7. Rebar – Strengthen Beams Rebar – Steel reinforcing rods • Beams experience tension on top and tension on the bottom • Concrete can withstand a great deal of compression but is weak when it comes to tension. Rebar helps resist tensile forces Concrete that contains rebar is called “reinforced concrete” • Made with ridges to ensure it grips the concrete • Rust resistant; Embedded in the concrete • Concrete and steel are used together because they contract and expand in regards to temperature in similar ways

  8. The Cantilever Niagara Falls New York Viewing Platform

  9. The Cantilever A beam that is only supported at one end When weight is placed on the other end of the beam, the beam bends in an n-shape to resist the load

  10. Cantilever Bridges cantilever bridges normally use pairs of cantilevers back to back with a short beam bridge in between the cantilevers. Modern motorways have cantilever bridges stretching across them, they have a cantilever coming out from each side and a beam bridge in between them.

  11. Supporting the BeamTie, Strut, Gusset Tie – a structural support that is part of the framework and designed to resist TENSION Strut – similar to a tie, but is placed below a beam where it provides resistance to the forces of compression (unlike columns, struts do not have to be vertical) Gusset – a flat, plate like device, often triangular that often supports a beam by reinforcing the connection between the beam and the support base

  12. Response Questions 1.) Briefly describe how a beam can be strengthened. What types of considerations would you need to think about? (hint – consider form and function) 2.) How is a Cantilever different from a fully supported beam? List some everyday examples of where we would see cantilevers ( at least three). 3.) As you are out and about in Kingston, try to spot uses of ties, struts, gussets. Record the location of some of these examples/the type of structure that is supported
