SEISMIC REDUCTION PERFORMANCE OF PREDICTIVE CONTROL VELOCITY PREDICTOR FOR SEMI-ACTIVE HYDRAULIC DAMPER
The component tests of velocity predictor based on displacement signals for semi-active hydraulic damper reveal that this calculation method can promote the seismic proof effect successfully. The displacement response of structure is random with random of earthquake excitation. In order to ensure the predictive application of this calculation method, shaking table tests are used to demonstrate the feasibility of this predictive method, predicting the reverse timing of moving direction of structure properly. Shaking table tests results indicate that the seismic reduction performances of this method are: 1.) the displacement reduction effect can promote 30%-40%; 2.) the acceleration reduction effect rise to 43%. This predictive method is suitable for strong earthquake and small-scale magnitude earthquake, happened frequently, based on the analytical results of this research.
