Abstract: |
In order to evaluate the effects of structural control and energy transition for the base-isolation with energy transducer (BIET), shaking table tests on a steel frame model (BIET system) with scale of 1:4 were conducted and the results were compared with the lead rubber bearing (LRB) isolation system for the same model. Then numerical analysis of the system was carried out, in which the improved Wen analytic model was used to simulate the hysteretic law of transducers. The results show that the structural system can transform the partial earthquake energy to hydraulic energy; furthermore, the effect of structural control can reach or be close to that of the LRB isolation system. The agreements between numerical analysis results and those of shaking table tests demonstrate the accuracy of the numerical model. |
