Damper frame

Abstract

A damper frame for dissipating seismic energy includes a structural frame and a damper assembly secured to the structural frame. The damper assembly includes a damper support secured to the structural frame. A damper is secured to the damper support adjacent a first end of the damper. A diagonal link is secured to the structural frame. A lever is secured to the damper support and the damper adjacent a second end of the damper opposite the first end of the damper. The first end of the damper is spaced vertically from the second end of the damper by a distance that is greater than a lateral distance between the first and second ends of the damper. The lever is connected to the diagonal link so displacement of the diagonal link relative to the damper support is amplified and transferred to the second end of the damper by the lever. The damper support includes a diagonal leg. The diagonal link and diagonal leg are arranged for telescoping movement relative to one another.
