Abstract
A device for separating the foundations of a construction from the construction itself. The device provides non-negligible damping of seismic oscillation and consists of a structural platform (A) supporting the construction (B), a sufficient number of suitably distributed suspension systems (C) to support the weight of the whole construction, and posts (D) secured to base plates (E). The suspension systems (C) are freely arranged inside a tapering space, and the finished ground level (F) is irrelevant. The device is particularly suitable for detached houses in earthquake zones.
Description
SYSTEME D'AMORTISSEMENT DE VIBRATIONS DISPOSITIF ANTI SISMIQUE POUR CONSTRUCTIONS INDIVIDUELLES VIBRATION DAMPING SYSTEM ANTI-SEISMIC DEVICE FOR INDIVIDUAL CONSTRUCTIONS
Domaine technioue : L'invention ci-aorès est destinée à 1 a réal i sati on de maisons individuelles résistantes aux oscillations sisπiαuesTechnical field: The invention below is intended for 1 a real i sati on of individual houses resistant to sisπiαues oscillations
Etat de la technioue antérieure Dans ce donaine , de nombreuses techniques existent oour la construction d ' imneubl es ou d'ouvraqes d'art . Toutes ces techniσues consisstent à réaliser des systèmes d * amorti ssements soitState of the prior art In this donaine, many techniques exist for the construction of buildings or works of art. All these techniques consist in realizing damping systems either
•iπinalité de l 'invention ci -jointe est de dissocier la construction proprement dite ( maison-habitation ) du sol au dessus duquel elle est construite . La construction ( maison-habitation ) est en effet solidaire d'une plateforme structurelle ne touchant pas le sol . Cette plateforme est alors reliée au sol nar un système de suspension intermédiaire , mobile dans . l 'esoace , réalisant ainsi l 'amortissement anti -si smique souhaité . • iπinality of the attached invention is to dissociate the actual construction (house-dwelling) from the ground above which it is built. The construction (house-dwelling) is indeed integral with a structural platform that does not touch the ground. This platform is then connected to the ground nar an intermediate suspension system, movable in. the esoace, thus achieving the desired anti-smog damping.
Lors de secousses sismiαues , l 'amortissement énerαétique se fait par oscillation de la Dlateforme supportant la construction . La construction proprement dite ( maison-habitation ) ayant la plateforπe structurelle comme système référentiel n'est donc pas soumise directement aux secousses sismiques et pourra donc être réalisée en matériaux plus légers , n'ayant pas à résister à des contraintes de déformation trop importantes .During earthquakes, the energy damping is done by oscillation of the Dlateforme supporting the construction. The actual construction (house-dwelling) having the structural platform as a referential system is therefore not directly subject to earthquakes and can therefore be made of lighter materials, not having to withstand excessive deformation constraints.

Exposé détaillé :Detailed presentation:
!) Desc<"iotif d'ensemble : L'ensemble se compose d'une plateforme A , de forme quelconoue, supportant la construction H , de systèmes ne suspension C en nombre et répartition suffisants pour supporter le poids de l'ensemble et de ooteaux D assujettis sur des socles E . le niveau du sol final F est indifférent .( &1 1/5 fig 1)!) Asc <"Comprehensive iotif: The assembly consists of a p lateforme A, quelconoue shape, supporting the building H, C suspension systems do in number and re p artition sufficient to support the weight of the set and of birds D fixed on bases E. the final level of the ground F is indifferent. (& 1 1/5 fig 1)
II) Principe : Le degré de liberté et d'amortissement de 1 a vi brati on est obtenu en désol i darisant la plateforme A suoportant la construction B, de l 'ensemble sol F incluant les Doteaux D et 1es socles E . La liaison des deux ensembles est obtenue oar 1 'intermédi ai re des susoensions C , articulées au ooint 0 sur 1es poteaux π et au point Q sur la Dlateforme A . La limite de 1iberté est di rectenent dépendante du diamétre φ 1 aissé libr a et de 1 a hauteur H entre 0 et G L'évolution dynamique du point G se fait donc à 1 'intérieur d'un cδne de centre 0 et de demi-angle au sommet 0( . La seu1e position d ' é quilibre stable de la pl ateforme A est obtenue 1 orsque le point G est à la verticale du point 0. L'angle Q( maximum est tel que sin θ( = φ / 2H ( planche 2/6 , fig 2II) Principle: The degree of freedom and damping from 1 to vi brati on is obtained by desol i darising the platform A supporting the construction B, of the ground assembly F including the Endings D and the bases E. The connection of the two sets is obtained by the intermediate of the suspensions C, articulated at the point 0 on the posts π and at point Q on the platform A. The limit of freedom is di dependent depending on the diameter φ 1 smooth free a and 1 at height H between 0 and G The dynamic evolution of the point G therefore takes place inside a cone with center 0 and half angle at apex 0 (. The only stable equilibrium position of platform A is obtained 1 when point G is vertical to point 0. Angle Q (maximum is such that sin θ (= φ / 2H (plate 2/6, fig 2
III) calcul : L'ensemble est en équilibre stable lorsque le poids P total de l'ensemble plateforme A + construction B est à sa position la plus basse par rapport au sol .III) calculation: The assembly is in stable equilibrium when the total weight P of the platform A + construction B assembly is at its lowest position relative to the ground.

T appliπué sur les suspensions et une force de rappel R oui ramène l 'ensemble vers sa position d'équilibre . si l 'anπle o< est tel αue sin tf = φ /2H on aura : R = P x tn <rf et h = H ( 1 - cos o( )T applied to the suspensions and a restoring force R yes brings the assembly back to its equilibrium position. if the anπle o <is such that sin tf = φ / 2H we will have: R = P x tn <rf and h = H (1 - cos o ()
L'ensemble est donc capable d'absorber une ^nerqie correspondant à la différence d'éneroie potentielle entre les niveaux ni et n2 .The set is therefore capable of absorbing a nerqia corresponding to the difference in potential energy between the levels ni and n2.
Soit : E ( joules ) = D ( newtons ) x h ( métrés )Let: E (joules) = D (newtons) xh (quantity)

Les éléments A , D et C seront réalisés dans tout matériau résistant et répondant aux critères de résistance ci -dessus .Elements A, D and C will be made of any resistant material and meeting the resistance criteria above.
Les suspensions C pouront être réalisées en acier plein , en câble , en chaîne , en cordage ou en fibres résistantes en incluant sur leur longueur H un dispositif de réglage de longueur genre ridoir S permettant d'ajuster le niveau final et l 'horizontalité de la plateforme A indépendamment de la position des poteaux D . VI ) Variantes :The suspensions C can be made of solid steel, cable, chain, cordage or resistant fibers by including on their length H a length adjuster like rigging screw S allowing to adjust the final level and the horizontality of the platform A regardless of the position of the posts D. VI) Variants:
Afin d'augmenter artificiellement 1 'amortissement de l 'oscillation , on pourra éventuellement installer les dispositifs de suspension non parallèles ( divergents ou convergents ) , ce qui aura pour effet d'arrêter le mouvement de balancement de la plateforme ( planche 4/6 fig Λ) ou placer entre les poteaux D et la plateforme A des amortisseurs complémentaires V de quelque type que ce soit, afin de limiter ces oscillations (planche 4/6 fig 5) par absorption d'énergie .
De même , toujours dans le but d'amortir plus rapidement les oscillations d'amortissement , on peut envisaqer oue les suspensions C soient réalisées dans un matériau rigide et encastrées en tête des poteaux D , à condition d'être articulées sur la plateforme A . ! .e moment de flexion complémentaire ainsi cré; est h ajouter ? la capacité d'absorotion énergétique d:'uu ssyyssttèèmmee (( ppllaanncchhee 55//66 ffiiaa 66 )In order to artificially increase the damping of the oscillation, it is possible to install non-parallel suspension devices (divergent or convergent), which will have the effect of stopping the rocking movement of the platform (board 4/6 fig Λ) or place additional dampers V of any type between the posts D and the platform A, in order to limit these oscillations (plate 4/6 fig 5) by energy absorption. Likewise, always with the aim of damping the damping oscillations more quickly, it is conceivable that the suspensions C are made of a rigid material and embedded at the top of the posts D, provided that they are articulated on the platform A. ! .e additional bending moment thus created; is h to add? the energy absorption capacity of: uu ssyyssttèèmmee ((ppllaanncchhee 55 // 66 ffiiaa 66)
En rai son d 'un manque de place autour de la construction 1 e POSiti onnenent des poteaux D peut se réaliser à 1 'intérieur du polygone de la plateforme A . En ce cas , les poteaux seront verticaux et reliés à la plateforme A par un système de plusieurs câbles ou suspentes C et la plateforme devra être percée d'un ori fiee de diamètre φ afin de laisser libre , comme ci- dessus , le mouvement pendulaire d'un demi anale au sommet ©< . ( planche 5/6 fig 7 )Due to a lack of space around construction 1 e POSiti onnenent posts D can be carried out inside the polygon of platform A. In this case, p will oteaux vertical and connected to the platform by a system of several cables or lines C and the platform must be pierced with a diameter φ FIEE orifice to allow free, as above, the movement pendulum of a half anal at the top © <. (plate 5/6 fig 7)
On peut penser également que la construction peut être suspendue par ses arêtes , la plateforme structurelle A étant située au dessus de la construction R , et intégrée alors dans la base de la toiture , oar exemple. Le socle de la construction ( plancher ) est donc situé au niveau du sol , sans le toucher . ( planche 5/6 fig 8 )We can also think that the construction can be suspended by its edges, the structural platform A being located above the construction R, and then integrated into the base of the roof, for example. The base of the construction (floor) is therefore located at ground level, without touching it. (plate 5/6 fig 8)
De même , on peut désolidariser complètement le système de suspension C et les poteaux D , du sol , en les reliant totalement , d'une manière rigide , à une armature W simplement posée à même le sol . De cette façon , la secousse sismique ne risque plus d'endommager ni la construction B sur la plateforme A , ni les poteaux D précédemment encastrés dans les fondations E. ( planche 5/6 fig 9 ) .Likewise, the suspension system C and the posts D can be completely detached from the ground, by connecting them completely, in a rigid manner, to a frame W simply placed on the ground. In this way, the earthquake no longer risks damaging either the construction B on the platform A, or the posts D previously embedded in the foundations E. (plate 5/6 fig 9).
