Earthquake simulation is a step ahead in science revolution. We all know how hazardous earthquakes could be when it occurs in a living place or industries. People have been struggling for years to find out how to prevent earthquake but that has never been possible until now. This new technique earthquake simulation is thus a simulation technique that helps to analyse the possible outcomes of how the effect of earthquake would be when it occurs on a man made engineered structures,or on natural features. During this simulation process, the effect of earthquake is completely studied on that particular location.
Earthquake simulation may involve dynamic experiments carried out on the building or non building structures which may be physical or virtual. Physical experiment is shake table testing and the non physical or virtual one is based on computer simulation.Those are carried out to verify how the structure’s seismic performance would be when an earthquake occurs.
Earthquake simulation first involved shake table testing. This method is to put the structure on a shake table that causes seismic loading and to watch the happenings. Computer simulation is now performed and it is an analytic method. Initially these simulations were performed by statically applying inertia forces horizontally based on the scaled peak ground accelerations to a schematic model of the building. Now due to improvements in this technology, the static approaches has been stopped and dynamic methods are being used. Numerical and physical simulation tests are performed separately.This new method is called hybrid testing and hybrid testing systems have been developed which employs rapid, parallel analyses using both physical and analytical methods.
Earthquake simulation games have also been developed these years which provide an interesting gaming experience.
