This design shows an application of a damage-controlled structure to a building having a diagonal lattice tube frame. The damage tolerant structure is a parallel combination of the primary structure and seismic dampers. The center portion of the diagonal lattice tube frame is made up of axial hysteretic dampers. The rigidity of the entire structure and the energy-absorption initiation level are controlled by varying cross-sectional areas of the diagonal columns and seismic dampers. By thus we have decreased the seismic responsiveness the conventionally elastically designed, diagonal lattice tube framed structure.
