Abstract.

In this article was researched the task of the eect of seismic isolation on the dynamic characteristics of the multi-story building. As an example was studied ve-story building on the rigidly xed foundation and taking into account seismic isolation in the form of a laminated rubber bearing support. Numerical results are obtained by solving the console calculation scheme using by the developed program. The results of the calculations of the displacements of the concentrated points along the height of the building according to the results of acceleration in the form of the damped sinusoid are compared.

Keywords: seismic isolation, dynamic characteristics, dry friction, model, viscoelastic connection, cantilever rod, grillage, viscosity coecient, support.

This article researches the stress-strain state of the frame building of the sports hall of secondary school No. 19 in Andijan under the seismic impact. The obtained numerical results of displacements and stresses in the supporting structures of the sports hall building are compared with the permissible values of displacements and stresses of the building structures.

Keywords. frame, column, crossbar, brick lling, T-section, truss, ribbed plate, stress-strain state, seismic eects, equivalent stress, displacement contour plots, stress contour plots, nite element method.
