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

9 The Cantilever Niagara Falls New York Viewing Platform

10 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

12 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.

13 Supporting the Beam Tie, 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

15 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
