Details and mechanical properties of bearings used in prototype structure.

Bearing	Number	Bearing details			Mechanical properties
		(mm)	(mm)	(mm)	(kN/mm)	(kN/mm)	(kN)	(kN/mm)
LRB1000	93	1000	190.4	200	5221	1.892	252	/
LRB800	34	800	185.6	160	3270	1.242	161	/
RB1000	20	1000	190.4	/	4649	/	/	4.649
RB800	19	800	185.6	/	2885	/	/	2.885

Note: D = bearing diameter; = total rubber thickness; = lead diameter; = vertical stiffness; = horizontal stiffness; = yielding force; = rubber bearing horizontal stiffness.
