Response Analysis And Vibroinsulation Of
Buildings Subject To Technical Seismicity

Abstract
Building structures in the vicinity of transport lines are loaded by vibrations
excited by the passage of motor vehicles or trains. These vibrations propagate as
technical seismicity effects through the soil to the foundations of buildings in the
vicinity of their source. Due to its tuning, the building structure usually amplifies
or, in better cases, reduces the effects of technical seismicity. An effective
method for reducing the vibration level of the protected structure as a whole with
reference to its foundation structures (plate, piles, strips, etc.) is to spring it from
the foundations. This springing is usually effected by placing the whole upper
part of the structure on individual springs or sprung layers. The effectiveness of
the springing is determined by the frequency tuning of the sprung structure. This
paper deals with the application of an elastic antivibration layer at the foundation
base level in order to eliminate excessive vibrations propagating to the assessed
building through the geological environment as technical seismicity.
Keywords: building structure, transport effects, vibroprotection, dynamic
response.
1 Introduction
The dynamic effects of subsurface traffic propagating through the ground
environment into the ambient buildings of urban agglomerations have been
acquiring ever-increasing importance. Construction firms make efforts to exploit
areas in the proximity of underground lines because of their lucrative location,
usually for residential construction. In the proximity of underground tunnels or
