Structures!
Structure Resources!!!!PEOPLEArchitect – person who designs buildings
and other structuresEngineer – person who applies the
principles of science and mathematics in the design and construction of a project
Continued…General Contractor – person or company
that takes overall responsibility for the construction project
Sub-contractor – person within the company with skills needed for a particular job
Little more…Project manager – oversees the
contacts, scheduling, material deliveries, and overall progress of the construction job
Tradesperson – the person who does the actual work on the job

Beam bridges
The simplest kind of bridge is called a beam bridge. These are used when crossing short distances. They strength of a beam bridge is determined by the strength of the beam used in its construction.
Arch BridgeThis type of bridge uses a curved structure
above an opening to support the load of a bridge. This type of bridge used commonly because the material that makes the arch remains very strong even under compression. Made from concrete and steel.
Suspension Bridge Longest type of bridge used to bridge wide
spans. Uses steel cables to hang the deck, or roadbed from towers. Modern suspension bridges have two tall towers to which the cables are attached.
George Washington Bridge Golden Gate Bridge
Cantilever BridgeLooks like two diving boards facing each
other. The sections are firmly attached at their ends. If they do not meet, another section could be added to link them. Requires a huge structure support on each end.
Buildings There are four basic types of
buildings:1.Residential2.Commercial 3. Institutional 4. Industrial
Investigate the structure…What do you need to consider
when developing building?Design (architect) Size (energy consumed)Cost (capital)Materials (steel, wood, concrete)TimeClimate/ region built in (windy, wet, hot)
ActivityWorking in teams of two, your task is to
build the tallest structure you can using 10 strands of spaghetti 1 sheet of paper 12’’ of masking tapeStructures must be freestanding
(structures cannot be taped to desk or taped to paper flat on desk, lean against something, or be held up with hands)
Make some plans and sketches of your ideas before you begin to use the supplies as you do not get replacements.
Reflection Writing AssignmentWrite an well-developed paragraph that addresses the following:What problems did your team encounter in planning and constructing your structure?
How did you overcome these problems?Compare and contrast your structure with the tallest structure that won the competition
If you could redo this activity using the same materials -
What would you do different?Why?
