Identification of Structure Dynamic Characteristics Using Forced Excitation Tests

Structure dynamic characteristics are defined as parameters which is used to predict the response of the system under loads with vibrating nature. Knowing the dynamic characteristics of a structure plays a vital role in understanding it`s behavior under seismic loads. It also helps engineers to improve their design to perform better under dynamic excitations including environmental excitations, stochastic excitations like earthquake and live load excitations. In order to identify these characteristics, Forced Excitation Tests (FETs) are one of common ways
