چکیده انگلیسی

The subject of the solution consists in the design and evaluation of vibro-isolation of the multifunctional reinforced concrete frame structure of a building over the tunnel metro structure, based on analysing its 3D calculation model. Measured vibrations in accelerations from passing metro trains were used as non-periodic excitation of the object on the level of its foundation slab. Results of the dynamic calculation are used to document the nature of the building structure response, and of the reduction/amplification of the vibrations at selected points of individual storeys during the pass of metro trains, including the frequency characteristics of the response. The comparison of the building response without and with vibro-isolation is used to demonstrate the efficiency of using a rubber layer in the footing bottom for reducing the transfer of vibrations from the metro to the building. Measurement of the vibrations when the construction had been finished allowed to compare the vibration prognosis to vibrations actually measured in the finished structure.
