Viability of Slab Sliding System for Single Story Structure

Slab sliding system (SSS) with Coulomb friction 
interface between slab and supporting frame is a passive structural 
vibration control technology. The system can significantly reduce the 
slab acceleration and accompanied lateral force of the frame. At the 
same time it is expected to cause the slab displacement magnification 
by sliding movement. To obtain the general comprehensive seismic 
response of a single story structure, inelastic response spectra were 
computed for a large ensemble of ground motions and a practical range 
of structural periods and friction coefficient values. It was shown that 
long period structures have no trade-off relation between force 
reduction and displacement magnification with respect to elastic 
response, unlike short period structures. For structures with the 
majority of mass in the slab, the displacement magnification value can 
be predicted according to simple inelastic displacement relation for 
inelastically responding SDOF structures because the system behaves 
elastically to a SDOF structure.
