Abstract: A robust vibration damping device not suffering from destruction even when an earthquake force is increased. A vibration damping wall structure includes a structural frame comprising a foundation, a beam, and vertical members. One set of vibration damping devices are attached to a first vertical member, and another set of vibration damping devices are attached at positions respectively opposing the one set of vibration damping devices to a second vertical member. Each of the vibration damping devices is connected with the vertical member by way of a brace. The vibration damping devices in the one set and opposing vibration damping devices in another set are connected each other in a lateral direction by lateral connection members between each of the sets. Further, the vibration damping devices of each of the sets are connected each other in a vertical direction by the vertical connection members respectively in each of the sets.

Abstract: An earthquake resistant reinforcement apparatus of a structure that can be attached simply and conveniently even to an aged building and imposes no substantial burden on inhabitants. The structure has an anti-seismic device for absorbing a seismic energy, an attaching member for attaching the anti-seismic device to the outside of a building, and a horizontal supporting member for supporting the anti-seismic device substantially horizontally. A plurality of attaching members are provided spot-wise to the girder or the beam of an existent building and the horizontal supporting member is a horizontal connection beam for connecting the attaching member horizontally.
