The damper assembly includes a damper support secured to the structural frame. A damper is secured to the damper support. A diagonal link is secured to the structural frame. A lever is secured to the damper support and the damper. The lever is pivotally connected to the diagonal link so displacement of the diagonal link is amplified and transferred to the damper. The damper support includes a laterally-extending cantilevered portion and the damper is secured to the damper support at the cantilevered portion. ## Claims ### Claim 1 A damper frame comprising: a structural frame; and a damper assembly secured to the structural frame, the damper assembly comprising: a damper support secured to the structural frame; a damper secured to the damper support adjacent a first end of the damper; a diagonal link secured to the structural frame; and a lever secured to the damper support and the damper adjacent a second end of the damper opposite the first end of the damper, the lever being 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, wherein the damper support comprises a laterally-extending cantilevered portion and the damper is secured to the damper support at the cantilevered portion. ### Claim 2 (depends on 1) The damper frame of claim 1 wherein the damper has a substantially vertical orientation within the structural frame. ### Claim 3 (depends on 1) The damper frame of claim 1, wherein the lever is pivotally secured to the damper support at a first location, pivotally secured to the diagonal link at a second location spaced a first distance from the first location, and pivotally secured to the damper at a third location spaced a second distance from the first location, the ratio of the second distance to the first distance being at least about 3. ### Claim 4 (depends on 3) The damper frame of claim 3 wherein the ratio of the second distance to the first distance is at least about 4. ### Claim 5 (depends on 1) The damper frame of claim 1, wherein the damper has a line of action and a line extending between the location where the lever is connected to the damper support and the location where the lever is connected to the damper is substantially perpendicular to the line of action of the damper. ### Claim 6 (depends on 1) The damper frame of claim 1, wherein 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. ### Claim 7 A damper assembly for dissipating seismic energy in a structural frame, the damper assembly comprising: a damper support; a damper secured to the damper support adjacent a first end of the damper; a lever secured to the damper support and the damper adjacent a second end of the damper opposite the first end of the damper; and a diagonal link connected to the lever 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, wherein the damper support comprises a laterally-extending cantilevered portion and the damper is secured to the damper support at the cantilevered portion; wherein the lever is pivotally secured to the damper support at a first location, pivotally secured to the diagonal link at a second location spaced a first distance from the first location, and pivotally secured to the damper at a third location spaced a second distance from the first location, the ratio of the second distance to the first distance being at least about 3. ### Claim 8 (depends on 7) The damper assembly of claim 7 wherein the ratio of the second distance to the first distance is at least about 4. ### Claim 9 (depends on 7) The damper assembly of claim 7, wherein the damper has a line of action and a line extending between the location where the lever is connected to the damper support and the location where the lever is connected to the damper is substantially perpendicular to the line of action of the damper. ### Claim 10 (depends on 7) The damper assembly of claim 7 wherein 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. ### Claim 11 A damper frame comprising: a generally rectangular structural frame includes a vertical left structural member, a vertical right structural member, a horizontal top structural member extending between the left and right structural members, and a horizontal bottom structural member spaced from the horizontal top structural member and extending between the left and right structural members; and a damper assembly secured to the structural frame, the damper assembly comprising: a damper support secured to the structural frame; a damper secured to the damper support adjacent a first end of the damper; a diagonal link secured to the structural frame; and a lever secured to the damper support and the damper adjacent a second end of the damper opposite the first end of the damper, the lever being 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, wherein the damper support comprises a laterally-extending cantilevered portion and the damper is secured to the damper support at the cantilevered portion. ### Claim 12 (depends on 11) The damper frame of claim 11, wherein the diagonal link is connected to the structural frame in a manner such that movement of the top structural member relative to the bottom structural member during a seismic event causes displacement of the diagonal link relative to the damper support. ### Claim 13 (depends on 12) The damper frame of claim 12, wherein the damper is adjacent one of the vertical structural members. ### Claim 14 (depends on 11) The damper frame of claim 11, wherein the diagonal link is pivotably secured to the structural frame. ### Claim 15 (depends on 14) The damper frame of claim 14, wherein the diagonal link is secured to the structural frame adjacent to the connection between one of the vertical structural members and one of the horizontal structural members. ### Claim 16 (depends on 15) The damper frame of claim 15, wherein an end of the diagonal link is pivotably secured to one of the vertical structural members and one of the horizontal structural members at the connection between said one vertical structural member and said one horizontal structural member. ### Claim 17 (depends on 16) The damper frame of claim 16, wherein the diagonal link extends across the structural from the end pivotably secured to one of the vertical structural members and one of the horizontal structural members toward the connection between the other vertical structural member and other horizontal structural member.
