Seismic Isolation Kinematic Foundation with Integrated Rubber-Metal Elastic-Damper Limit

There are various designs of seismic isolation of buildings and structures, in the foundations of which spherical surfaces with rolling balls, rubber-metal layered seismic isolators, as well as complex metal spring seismic isolators are used. The goal was to create such a seismic isolation foundation, which would simultaneously combine all the advantages of the above seismic isolators. There are various designs of seismic isolation of buildings and structures, in the foundations of which spherical surfaces with rolling balls, rubber-metal layered seismic isolators, as well as complex metal spring seismic isolators are used. The goal was to create such a seismic isolation foundation, which would simultaneously combine all the advantages of the above seismic isolators. A new seismic isolation foundation of the building has been developed, which includes the upper and lower supporting parts, in which cylinder sleeves with inclined bottoms are formed, an intermediate element in the form of a ball and an elastic insert. The elastic insert is located on the bottoms of the upper and lower cylinder sleeves, and on the surface of the bottom of the sleeve and each insert, a steel Belleville spring 5 mm thick is located and fastened to them. In each cup, the elastic liner forms a complex non-linear surface around the intermediate element, which in the section forms ascending halves of a sinusoid, which is a companion of the cycloid built in a circle with a diameter equal to half the diameter of the intermediate element. In this case, there is a gap of 10 mm between the end surfaces of the walls of sleeves.
