  • Technology of high-precision installation of kinematic seismic isolation support

    The article is devoted to solving the problem of high-precision installation and alignment of kinematic supports on ball rolling bodies, a detailed description of the design solution for precise fixation of ball rolling bodies on a flat monolithic concrete foundation during installation of a seismic insulating support and describes the phased construction of all elements of kinematic seismic insulating supports in the underground part of a high-rise building.A system of seismic-insulating kinematic supports installed in the underground part of a high-rise building is considered. An improved method of high-precision installation of kinematic seismic isolation supports is proposed, which allows to increase the accuracy of installing a seismic support on a system of four rolling elements. The technology of mounting seismic supports on the zero cycle of construction of a high-rise building is described. The advantages are evaluated.

  • System of oscillations indemnification of a high-rise construction in a seismoactive zone

    Systems of passive damping of oscillations of high-rise constructions are considered. Their merits and demerits are revealed.  The roller  system of  oscillations indemnification  of the high-rise constructions subject to seismic influence is offered.  The principle of its work is described.  Advantages are estimated.

    Keywords: high-rise construction, damping of oscillations, passive systems, roller system of indemnification, vibroisolation
