![]() So-called hybrid testing systems employ rapid, parallel analyses using both physical and computational tests. Traditionally, numerical simulation and physical tests have been uncoupled and performed separately. With the further development of computational technologies, static approaches began to give way to dynamic ones. ![]() 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. Computational approaches Īnother way is to evaluate the earthquake performance analytically. The earliest such experiments were performed more than a century ago. ![]() Two different geological foundations, bedrock and water-saturated sand, are tested to show the. Several different construction materials are used to demonstrate what type best survives an earthquake. Studying a building's response to an earthquake is performed by putting a model of the structure on a shake-table that simulates the seismic loading. An earthquake simulator, or seismic table is constructed and then used to test the structural soundness of several types of student built houses.
