Abstract.

Some problems of the construction of a residential complex with a system of seismic and vibration protection from railway trains are considered. The estimated seismicity of the construction site is 6 points according to the current standards [1]. The construction site is located at the railway line. During the movement of trains and vehicles, soil vibrations are transmitted to the building constructions. The prevailing frequencies of dynamic effects from railway trains and motor vehicles are in the range of 10-80 Hz. Frequencies of natural vertical oscillations of floors in the living rooms of houses range from 20 to 50 Hz. Therefore, the dynamic effects of trains are the cause of increased (close to resonant) oscillations of floors of buildings located along the way.

The use of vibration protection systems based on elastomeric vibration dampers (vibration isolators based on natural rubber) has become widespread both at industrial enterprises and at reduced man-made impacts (vibrations) on people in residential buildings, especially in megacities of Ukraine (vibration protection from underground and land transport: trains of a metro, tram, rail and road transport). Vibro- and seismic protection systems based on domestic elastomer vibration dampers developed in Ukraine to protect buildings and structures from strong and destructive earthquakes allow designing seismic resistant, comfortable and economical building constructions.

Vibration insulation of buildings from railway train vibrations is carried out by installing rubber or rubber-metal vibration insulators between the base plate and the walls of the basement building.

The article presents the results of experimental studies on solving the problem of vibration isolation of multi-storey buildings at the level of a pile grillage from railroad trains and motor vehicles. The results of the work performed allowed us to obtain accelerograms of the soil surface at the construction site; to carry out the development of dynamic models of vibration-insulated 6, 10 and 13-storey sections of a residential house for carrying out calculations and develop recommendations on the design of units of the device of vibration isolators and the system of seismic and vibration protection of the sections of the house in order to reduce the dynamic effects of railway trains to permissible under Sanitary standards.
