[[Building|Building structures]] or large [[nonbuilding structure]]s (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 [[earthquake]]s. 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 [[Earthquake shaking table|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 analysis|finite element software]].
