摘要:
An elastic wave damping structure can include a structural arrangement of at least two elements, each with an inner volume and containing a medium resistant to passage of an elastic wave. Example elements can be earth boreholes or water pylons. The structural arrangement can taper from an upper aperture to a lower aperture, the structural arrangement defining a protection zone at the upper aperture. The structural arrangement can be configured to attenuate power from the anticipated elastic wave within the protection zone relative to power from the anticipated elastic wave external to the protection zone. A grouping may include elements that form acute or obtuse angles with a direction of an elastic wave to attenuate wave power. High-value buildings or other structure in a protection zone on land or in water can be substantially shielded from seismic or water waves.

A seismic device for insulating buildings comprises a group of at least three plates (1, 2, 3) overlapping each other and having respective faces facing each other shaped to define, between each pair (1, 2; 2, 3) of facing plates, at least one pair of channels (12). Each channels (12) house at least one roller (5, 6) adapted to allow relative sliding in a horizontal plane of the plates (1, 2, 3) for the absorption of horizontal oscillations produced by an earthquake. The channels (12) between the lower plate (1) and the intermediate plate (2) have a development direction orthogonal with respect to the channels (12) defined between the intermediate plate (2) and the top plate (3) of the group. Elastic damping means are also provided and arranged below the group of plates (1, 2, 3) and comprise a plurality of cushions (9) inflated to a predetermined controlled pressure and arranged below the lower plate (1) to raise said group from the ground and absorb the load and the vertical oscillations produced by the earthquake.

A three part foundation system for supporting a building is described. Three part foundation systems can include a containment vessel, which constrains a buffer medium to an area above the containment vessel, and a construction platform. A building can be built on the construction platform. In a particular embodiment, during operation, the construction platform and structures built on the construction platform can float on the buffer medium. In an earthquake, a construction platform floating on a buffer medium may experience greatly reduced shear forces. In a flood, a construction platform floating on a buffer medium can be configured to rise as water levels rise to limit flood damage.

Seismic base isolation and energy dissipation device using a plurality of multi-walled swing plate's that are placed on many central walls that are attached to a base support structure. This arrangement creates a strong load bearing multi-walled swing beam that moves in true pendulum fashion. This system is placed between the structural load and its foundation. This seismic wave base isolation system has the purpose of absorbing seismic wave displacement energy in all directions. This unique design can scale up for very large and heavy loads or scale down to protect sensitive cargo and equipment from destructive motion. The multi-walled swing plates inside the multi-walled swing beam will provide support and absorption of motion by moving as a pendulum and therefore redirecting and dissipating seismic energy. This invention is particularly suited to reduce the initial shock of horizontal ground displacement. This system has a simple design shape and is therefore inexpensive to construct, is easy to engineer and deploy, it requires no uncommon material and requires very little maintenance or advanced electronics.

A fluid transport system for actively damping oscillations of a structure affixed to a ground surface is disclosed. The system includes a pipe defining a flow path, a driver in fluid communication with the pipe and configured to provide a fluid flow through the pipe, and a controller. The controller is programmed to send a fluid flow command signal in response to an event signal indicating an oscillation event.

The invention is directed to develop for the construction method for strong resistance to the earthquake according to new architecture rationale which all construction for building should be founded on the platform to be moved in alignment with the movement of the earthquake eliminating any piles to drive into the earth to adhere and building materials to combine each other firmly, by means of converting the vibration energy of the earthquake into the kinetic energy either to run idle the balls or to operate the up and down movement of the cylinder applied to the pile as the leg of the building rested on the ground in alignment with the movement of earthquake to deteriorate efficiency of transmissibility or to consume away for vibration energy of the earthquake as much as possible from an architectural point of view, it were just like idling operation as if car tires have sunk into sand.
