An object, such as a building, provided with a system for preventing damage from earthquakes to the object, said system comprising:
a foundation anchored to the ground;guide means mounted on said foundation and on said object arranged to allow relative displacement between the object and the foundation in at least one horizontal direction;at least one actuator arranged to displace said object in said at least one direction relative to said foundation;said at least one actuator being connected to a central processing unit;
said central processing unit being connected to at least one displacement sensor;
said at least one displacement sensor being arranged to detect in real time displacement of said foundation and/or the ground and/or said object and to input in real time data about said displacement to said central processing unit; and
said processing unit being programmed to activate in real time said actuator in dependence on said data in such a manner that said object is displaced relative to said foundation in real time, such that the maximum displacement vector of the object relative to the earth's gravitational field is kept substantially smaller than the maximum displacement vector of said foundation relative to the earth's gravitational field. |
