Abstract:
A rigid substructure ( 12 ) tied to a restrained column ( 16 ) at different floors undergoes rigid body rotation due to lateral dynamic loading. Flexural members ( 18 ) that are connected to the substructure ( 12 ) and another anchor column ( 14 ) resist the rigid body rotation and undergo vertical deflections. Damped diagonals ( 20 ) connected to common nodes of the rigid substructure and flexural members, for one embodiment, receive amplified displacements and more effectively dissipate energy. Flexural members restore the structure to the unloaded position. The system does not require moment connections and can work with flexure induced in simply supported beams. The system is highly effective and may remain elastic under maximum considered earthquake ground motions.

Claim (Index 1):
A rigid substructure damping system for protecting a structure when subjected to dynamic forces, the structure having at least one rigid substructure that is comprised of a segment of one column and only one between two floor levels, that are not necessarily consecutive floors, called restrained column here, and other structural elements to form a rigid substructure within a plane and with nodal points on the restrained column including nodal points at the two floors and other nodes at a horizontal distance from the restrained column, called active nodes, and with sufficient rigidity and turnable geometry for the rigid substructure such that drift between the two floor levels, induced by the dynamic forces, would effectively cause rigid body rotation of the substructure, mobilizing active nodes in horizontal and vertical directions; and\n another column which is different from the restrained column and is not directly connected to any node of the substructure, called an anchor column here that connects to other elements of the system at nodes referred to as anchor nodes; and one or more flexural members each connected to the anchor column and to one or more active nodes, with connection types and or continuity such that vertical displacement of the active nodes connected to the flexural member would induce bending in the flexural member, opposing the drift in the structure and stabilizing the structural system; and one or more elongated damped diagonals each connected from the first end, operatively to an anchor node and from the second end to an active node or to a node on a flexural member selected such that the node undergoes vertical displacement, with any type of damper installed on the diagonal that can dissipate energy due to relative movement of the ends of the diagonal.
