Testing of Large Structures
Building structures or large nonbuilding structures (such as dams and bridges) are rarely subjected to destructive testing due to the prohibitive cost of constructing a building, or a scale model of a building, just to destroy it.
Earthquake engineering requires a good understanding of how structures will perform at earthquakes. Destructive tests are more frequently carried out for structures which are to be constructed in earthquake zones. Such tests are sometimes referred to as crash tests, and they are carried out to verify the designed seismic performance of a new building, or the actual performance of an existing building. The tests are, mostly, carried out on a platform called a shake-table which is designed to shake in the same manner as an earthquake. Results of those tests often include the corresponding shake-table videos.
Testing of structures in earthquakes is increasingly done by modelling the structure using specialist finite element software.

Famous quotes containing the words testing of, testing, large and/or structures:
“In the gold mouth of a flower
the black smell of spring earth.
No more skulls on our desks
but the pervasive
testing of death....”
—Denise Levertov (b. 1923)
“No testing has overtaken you that is not common to everyone. God is faithful, and he will not let you be tested beyond your strength, but with the testing he will also provide the way out so that you may be able to endure it.”
—Bible: New Testament, 1 Corinthians 10:13.
“The tumultuous populace of large cities are ever to be dreaded. Their indiscriminate violence prostrates for the time all public authority, and its consequences are sometimes extensive and terrible.”
—George Washington (1732–1799)
“If there are people who feel that God wants them to change the structures of society, that is something between them and their God. We must serve him in whatever way we are called. I am called to help the individual; to love each poor person. Not to deal with institutions. I am in no position to judge.”
—Mother Teresa (b. 1910)
