We use text, graphics and animations to help students to learn about structures, including simple tests that can be used with structures to ensure that structures will withstand dynamic loads and will not collapse in use.

Testing Structures

A structure is tested to check how well it withstands forces applied to it and how it behaves under load.

Examples of tests that may be carried out on a structure include tests that check that:

• the structure withstands the static and dynamic loads it was designed for; the tests may include:
  • tension tests
  • compression tests,
  • torsion tests
  • tests that show the effects of dynamic loads, including:
    • impacts
    • crashes
    • vibration
    • air pressure
    • wind pressure
    • water pressure
    • earth tremor / earthquake
• the structure can carry at least four times the load it is normally expected to carry (the factor of safety)
• the structure does not collapse in use
• the structure is stable
• the best materials have been used for the structure
• the best joining methods for the various structural parts have been used - various joints may be tested under the conditions that the structure will be used
• the structure withstands the effects of friction and wear
• the structure is energy efficient
  • in the way that the structure is made
  • in its use of energy
  • in its conservation of energy
• quality control tests that ensure that the structure is built to the standards required by the product specification.
