SEASONIC RESISTANCE OF MULTI-STORY BUILDINGS IN BUKHARA CITY TO NON-STATIONARY SEISMIC IMPACTS

Under the influence of dynamic and static loads, a change in the volume of weak soils in the foundation occurs due to a decrease in porosity. In this regard, studies have been conducted on the seismic resistance of buildings, the basis of which is elastic-plastic layers. As a result, the equation of motion of the soil was obtained to determine the total slope angle of the building, taking into account the seismic effect characteristic of the construction site and the specific characteristics of the building. The increase in risk due to the loss of priority of the foundation due to the possible slope of the building is shown. Parameters affecting the kinematic properties of buildings and structures are shown. The elastic system consisting of the building and the foundation has one-way connections between the foundation and the foundation, which are found to move away under the influence of seismic forces in individual sections of the foundation foundation with low static loads. Removing the connections changes the stiffness of the system. The center of gravity and the center of mass are shifted by a certain distance, and therefore, variable vibrations arise. The range of vibrations depends on the ratio of the natural frequencies of the buildings and the seismic waves. The results of the study, along with other calculations that allow increasing seismic resistance, can be used in the calculation of multi-storey and multi-storey buildings built on weakly deformable soils.
