Adjacent structures controlled by elasto-plastic steel devices

In this paper a shaking table test to improve the effectiveness of passive control of adjacent struc- tures by means of hysteretic devices is presented. This configuration might be typically find in civil and industrial applications. The test structure is a 1:5 scaled coupled structures model of different height and mass. The two structures are connected by using elasto-plastic devices. For two adjacent multi degree of freedom systems the problem of optimal design of hysteretic connections is also studied. The model undergoes different earthquakes of different intensity. The control performances of the passive control are compared with both the uncoupled and the rigid-connection structures cases. Results clearly show the good performance of the proposed control approach.
