Özet
This paper presents an experimental investigation for deflection control of two degree of freedom building-like structure system against scaled Northridge Earthquake by using PI (Proportional-Integral) controlled active mass damping. Proposed structure consist of two floors with a cart mounted on the second floor such as active mass damping (AMID) and which is used to suppress horizontal deflections. Moreover a shake table under the structure is used to create the acceleration effect of scaled earthquake. K-p and K-i gain parameters of PI controller is determined by observing passive mode behaviour of the structure against Northridge and it is used to control cart movement according to pre-determined deflection criterias of the floors. Deflection and acceleration results of the floors are obtained separately for passive and active mode responses of the system in the form of graphics.
