Abstract
A damping device includes a plurality of rockets (3) each having a nozzle (4) directed outward and disposed at the four corners on the upper floor of a building structure (1) and a device for sensing an earthquake and operating the rockets. With this arrangement, there can be provided a damping device for a building structure which is applicable not only to new building structures but also to existing building structures and can cope with a sudden exciting force caused by, for example, an earthquake with a vertical shock which has been conventionally impossible to be coped with.
