DESCRIPTION:In the last decade\, the focus of performance-based earthquake
  engineering has shifted towards the design of earthquake resilient struct
 ures. Therefore\, an important challenge today is to provide design soluti
 ons where residual structural damage is minimized. Rocking mechanisms at t
 he foundation-structure interface have been proposed to isolate the struct
 ure by limiting the inertial forces on the superstructure. This presentati
 on investigates the ability of rocking to isolate structures from strong g
 round motion. \nThe talk will start with a brief discussion on the critica
 l differences between conventional base isolation and rocking isolation. A
  review of early studies and designs will then demonstrate how pioneering 
 engineers dealt with the differences concerning the nonlinearity of rockin
 g response and its interaction with structural vibrations. Then\, a detail
 ed analytical and experimental investigation of the fundamental dynamics o
 f idealized flexible rocking structures will follow. This investigation hi
 ghlights the coupling of rocking action with vibrations\, and demonstrates
  how this coupling modifies the vibration response of the structure. The f
 indings are further discussed to evaluate the aforementioned design assump
 tions and to investigate how to improve dynamic performance by utilizing d
 ampers. \n
