Abstract
The reaction of a building with a kinematic seismic isolation system to wind force and its analysis by means of Lira-SAPR
Incoming article date: 03.12.2020The article describes the device and principle of operation of the Kurzanov-Semyonov kinematic support. Advantages and disadvantages of this type seismic isolation are also highlighted. In addition, the structural design scheme of the operated high-rise apartment building with and without kinematic support system was created in the Lira-CAD software package (CAE FEA software). Based on the computing results, a comparative analysis of the reaction of the building superstructure block under the influence of wind force in three directions was carried out. It was determined that the wind force does not affect the performance of the kinematic support system negatively.
