ABSTRACTThis poster is aimed to contrast the advantages of the hybrid simulationmethod to simulate structural behavior on structural components tocharacterized seismic response.INTRODUCTIONThe mitigation of structural damage caused by lateral forces induced bymajor ground motions is an essential governmental duty since economicand human losses can be catastrophic. Hence, building codes haveundergone significant changes to achieve earthquake-resistantconstructions. Most of the improvements are a consequence ofexperimental research because assuming material behavior under criticaldemands becomes extremely complicated. For this reason, hybridsimulation is beneficial in terms of cost, time consumption ,equipmentavailability and the credibility of result in Seismic/Structural Engineering.TESTING PROTOCOLS ADVANTAGESCONCLUSIONSREFERENCES • Xxxxxxxxxxxx• X• X• X• X8.WHAT ARE THE BENEFITS OF USING A HYBRID SIMULATION IN STRUCTURAL AND SEISMIC ENGINEERING?
