Anti-seismic reinforcement and expansion method for building and anti-seismically reinforced and expanded building

A method of expanding a mid-rise building to a high-rise building, where a quake-absorbing foundation (5) for a high-rise building is newly provided outside the foundation of an existing mid-rise building (1), support members (6) are stood on the newly provided quake-absorbing foundation, and new dwelling floors (10) are fabricated above the existing building using the support members. After the completion of the new dwelling floors, upper floors of the existing mid-rise building are dismantled and removed and remaining individual floors of the building are remodeled sequentially. Thus, with the dwellers living in the building, a mid-rise building can be expanded to a high-rise building having excellent quake-resistance.

Earthquake protection sliding member

The invention relates to a system comprising two sliding members 11 and 14 in contact with each other. Sliding member 14 is of stainless steel whilst sliding member 11 comprises a stainless steel backing plate 12 onto which are attached materials 13a-13e. The materials are of increasing coefficient of friction from low 13a to high 13e. Thus in use a greater degree of resistance is applied to sliding element 14 as the displacement of 14 is increased. The system is intended for use for example between columns and floors in buildings to provide damping of vibrations from earthquakes, a further embodiment employs the system in a brake for a railed vehicle.

Earthquake protection consisting of vibration-isolated mounting of buildings and objects using virtual pendulums with long cycles

Earthquake protection consisting of vibration isolated mounting of buildings and objects using using virtual pedulums with long circles.

The invention relates to an earthquake protection system which is entirely immune to seismic activity. The inventive system supports buildings and other objects on virtual pendulums (pv)configured according to the invention in the form of earthquake protection modules (56). In the case of relatively low buildings, the limit load support points of said earthquake protection modules (56)move in the manner of the oscillating end of a long pendulum with along cycle of its own, so that the object being supported is efficiently isolated from the essentially more frequent ground vibrations. The functional behaviour of the system is not affected by the extent of the base acceleration or the frequency of the ground vibration. Even in the case of a large earthquake, the object will remain still. The system can be configured for any load and any conceivable scale of vibration. The invention describes four different examples of solutions which apply the inventive method, variants and devices derived ...

Its design permits upward movement by ripping the shear bolts through the metal body or breaking the shear bolts off if the ground should rise as caused by an earthquake or massive explosion. Its design permits downward movement by deforming the opposed angles or ridges of the upper and lower elements of the unit if the ground should sink as caused by an earthquake or massive explosion. Its design will permit it to be installed in new construction in such a way that all of the concentrated loads of the superstructure will be supported by a sufficient number of the ...

Le dispositif imaginé pour amortir les secousses sismiques transmises à un immeuble permet d'abord, à cet immeuble, de ne pas être entraîné par les déplacements latéraux du sol. Résultat possible grâce à des plaques glissantes interposées entre la base des murs, coiffés d'un sabot et leur assise. Le frottement entre ces plaques, de duretés différentes, peut être encore réduit par la pression verticale, sous le plancher du rez-de-chaussée d'un fluide contenu sous un réservoir sous-jacent, comprimé par celui d'une colonne centrale de hauteur adéquate. La pression de ce fluide atténue également l'effet de désagrégation des secousses sismiques verticales. Pour les annihiler à peu près totalement, des ressorts de compression sont interposés entre le sabot et la base des murs qu'il coiffe. Ces ressorts absorbent de l'énergie quand le sol est soulevé et ils la restituent lorsqu'il s'affaisse. L'immeuble ne s'écarte pas sensiblement de son niveau initial. (CF DESSIN DANS BOPI) ...

Gravity-Derived Structure For Optimal Response To Gravitational Forces

A structure, such as a tower/building/column/beam/bridge/machine, is composed of elements that are arranged in a manner to optimally respond to any destructive force applied upon it. Using physical models that expose the effects of gravitational forces shows that the density of the structural elements of a structure should gradually increase from top to bottom in order for the structure to optimally respond to these and other forces. For optimal response to vibrational forces traveling through a structure/tower/bridge/machine, the structure should be divided in segments that satisfy the Formulas 1, 2, 3, Page 4 of this application. When a structure is divided into segments such that one, or two, or any ratio between these is an Irrational number, the vibration cannot travel through the structure because there isn't a wave length that fits through these different segments.
