Claim:
1. An apparatus for resisting potentially destructive movement within a building structure, comprising: a damper designed for resisting at least one of an extension force and a compression force, and having one or more attachment interfaces, said damper is fixedly mounted to a structural member located along a first side of a bay within a building structure; a first rod having a first end that is attached to a first attachment interface of said damper, said first rod having a second end that is attached to a first arm of a first bell crank; a second rod having a first end that is attached to a second arm of said first bell crank; and said second rod having a second end that is attached to a first end anchor; wherein said first end anchor is fixedly mounted on a structural member located along a second side of said bay; and wherein relative motion between said first side and said second side of said bay causes either an extension force or a compression force to be applied to said damper, causing resistance to said relative motion via said damper; and wherein there is no point location within said structural member, said damper, said first rod, said bell crank or said second rod, that is located as or more proximate to a geometric center point location within said bay, in relation to any one nearest side of said bay; without effect of said relative motion.
