LEAD RUBBER BEARING SYSTEM FOR SEISMIC ISOLATION OF REINFORCED CONCRETE STRUCTURES

seismic isolation technoloty has been applied to protect civil structures from earthquake damage for over two decades . Observed performance of several practical cases has revealed the success of seismic isolation technique in reducint earthquake induced forces the base isolation method is used to design structures aganist earthquake damages by using seismic isolators to change the dynamic charateristics of a structure.
