A novel connected control system applicable to a single building by dividing it into four internally
In structural vibration control problem,it is always a big issue how to obtain the proper reaction force to reduce structural vibration.To solve this problem,“Connected Control Method(CCM)is already presented.Suppose two or more buildings are built close enough to connect them with viaducts.If these viaducts are able to change their spans,it is possible to utilize these viaducts to dissipate vibration energy by inserting certain damping materials.In this case,the reaction force of one viaduct for a building is utilized as the control force for other buildings.One of the authors has presented this idea and named it as “Connected Control Method. The CCM has been already put into practical use,while the restriction that CCM requires at least two buildings to obtain reaction force prevents further development.To overcome this restriction and develop CCM,a novel idea to apply CCM onto a single building is presented.First,splitting the building into four substructures that possess the same height and the same number of floors but different natural frequencies(or construct the building as an aggregate of four such substructures).To form single building,the floors of the four substructures in the same height would be coupled via elastic joints such as sliding couplers or expansion joints.Putting dampers in the joints(namely between substructures),the aggregate,four substructures coupled with dampers,forms a single building equipped with CCM.This is named “Integrated connected control method(ICCM). In this paper,the idea of ICCM is presented for a vibration control method for high-rise buildings against large earthquake excitation.An experimental model structure is built and four magnetic dampers are introduced to realize ICCM.Experimental evaluations are carried out to verify the applicability of the ICCM.
