Claim 17:
18. The device of claim 1 wherein the second anchors fix the second end regions of the yield plate, to a second structural member, being a base, or foundation, or floor;
the first anchor fixes the first region of the plate to a first structural member, being, the base of a chord of a structural frame;
the second anchors and second end regions of the plate configured with boundary conditions whereby the plate is able to cyclically flex, under the action of uplift loads from the chord, away from the base or foundation or floor, and form a curve with a convex top surface, and the plate being able to return flex to the base or foundation or floor under the action of reverse loading from the chord;
the yield plate being able to cyclically flex and flexurally yield at first region, without generating any prying action between second regions and second anchors or second structural member or the base or foundation or floor, or cause or allow any membrane forces to develop within the yield plate, while the yield plate maintains a constant resistive yield force within and across itself and a constant resistive yield force between first and second structural members as they displace relative to each other in response to base motion input from a seismic event.
