Earthquake simulation

The very first earthquake simulations were performed by statically applying some "horizontal inertia forces", based on scaled peak ground accelerations, to a mathematical model of a building cite book|title= Seismic Design of Building Structures|author=Lindeburg, Michael R.; Baradar, Majid|date=2001|publisher=Professional Publications|isbn=1888577525] . With the further development of computational technologies, static approaches began to give way to dynamic ones.Dynamic experiments on building and non-building structures may be physical, like shake-table testing, or virtual ones. In both cases, to verify a structure's expected seismic performance, researchers prefer to deal with so called “real time-histories” though the last cannot be “real” for a hypothetical earthquake specified by either a building code or by some particular research requirements. Therefore, there is a strong incentive to engage an earthquake simulation which is the seismic input that possesses only essential features of a real event, like, e.g., the earthquake simulating displacement time-history "Cone" [https://central.nees.org/data/get/NEES-2006-0283/Public/REPORT.pdf] presented above.

Earthquake simulations have been widely used in the research of Earthquake Protector and development of the EPET which was supported by The George E. Brown Network for Earthquake Engineering Simulation (NEES) [http://www.nsf.gov/news/special_reports/nees/about.jsp] .

Sometimes, earthquake simulation is understood as a re-creation of local effects of a strong shaking [http://tw.youtube.com/watch?v=UcgRtZKRip0] .
