DESCRIPTION:Numerous structures exhibit rocking behaviour when loaded dyna
 mically\, including monuments\, towers\, bridge piers\, sculptures\, etc. 
 Recent earthquakes have increased world-wide incentive to retrofit such st
 ructures to avoid collapse during dynamic loading. \nIn practice\, rocking
  behaviour is typically prevented by tying structures down or reinforcing 
 them. While these methods can be effective\, they can over-stiffen structu
 res\, add stress\, and be destructive.\n\nThis research lays the foundatio
 n for the development of a new class of retrofit solutions which exploit d
 amping systems\, through analytical and experimental modeling. Also\, a pi
 lot application of the proposed approach to a particular class of rocking 
 problems\, the masonry arches is presented. Further\, this research offers
  an alternative way to describe the response of the rocking block\, based 
 on dimensional and orientational analysis\, which brings forward the prope
 rty of self-similarity for rocking structures. \n
