The invention relates to an earthquake protection system that is entirely immune to seismic activity. According to the inventive method buildings and other objects are supported by Virtual Pendulums (P v) designed as QuakeProtect Modules (56). Although requiring only little height for installation, these earthquake protection modules allow a freedom of movement for the load bearing support points of the supported structure as if they were the oscillating ends of long pendulums with long cycles of their own. As the result of which the supported object is efficiently isolated from the considerably higher frequent earthquake ground oscillations. The functional behavior of the system is not affected by the extent of the base acceleration or the frequency of the ground oscillation. Even in an earthquake of greatest magnitude the supported object will remain still. The system can be configured for any load and any conceivable ground oscillation amplitudes. The invention describes four different examples of solutions that apply the inventive method, variants and devices derived therefrom for various applications. Additionally are described devices needed to provide support against wind forces and to center a supported object under wind loads and during ground oscillations, and as well devices for the isolation of vertical ground oscillations.
L'invention concerne un système antisismique entièrement immun permettant la protection des bâtiments et objets. Selon ce système, les bâtiments et objets reposent sur un pendule virtuel (Pv) conçu sous forme de modules de protection antisismique (56) dont les points d'appui de la charge ont un comportement mobile pour une faible hauteur de construction comme l'extrémité oscillante d'un long pendule avec une grande période de l'oscillation propre. L'objet porté est ainsi efficacement découplé des ondes sismiques de grande fréquence. Le fonctionnement du système n'est pas influencé par l'importance de l'accélération de la base et la fréquence de l'onde sismique. Même en présence de tremblements de terre de grande magnitude, l'objet porté reste en position de repos. Le système selon l'invention peut être conçu pour toute charge et toute amplitude attendue des oscillations de la base. L'invention concerne quatre solutions différentes d'application du procédé, les variantes qui en découlent et les dispositifs correspondants et les dispositifs supplémentaires nécessaires destinés à l'appui de l'énergie éolienne et au centrage de l'objet sous l'action du vent en cas de base oscillante ainsi que les dispositifs destinés à découpler les ondes sismiques verticales.
