Large building vibration isolation – New buildings, located on plots of land that are subject to vibrations are being constructed every day. Whether this vibration present in the ground is due to nearby railway lines, roads or industrial complexes, if it is not correctly addressed then problems can arise. These problems can manifest themselves as simply the vibration, or, more predominantly, in the form of re-radiated noise caused by the vibration of different structural elements such as floors and walls, as well as all fixtures and fittings.

Why is there an increasing requirement for a large building vibration isolation?

  • Increasing urban density and the desire to develop on any profitable land has led to buildings being constructed in close proximity to existing transport infrastructure or industrial developments.
  • Maximizing the value of these developments and the associated client expectations.
  • Tendency towards more lightweight construction with larger span slabs that are more prone to vibration problems.
  • Increased legislation and guidance from projects such as Crossrail.

The isolation of a raft or basement slab on a full-surface elastic bearing such as Sylomer or Sylodyn, effectively isolates everything that is built up off the slab from the vibrations present in the ground.

With achievable natural frequencies down to about 8-9Hz with thicknesses of material from 12.5mm to about 50mm, Sylomer and Sylodyn full surface bearings offer a simple, effective, easy to install solutions, that impacts minimally on the overall design and construction of the building.

When isolating on pile-caps or on column heads, the Sylodyn HRB materials offer a very high load capacity solution, capable of providing natural frequencies as low as 6-7Hz. Typical thicknesses of bearing can range from 12.5mm to 75mm (greater for specific projects).

With excellent creep performance and resistance to fluids and chemicals often present in construction and industrial applications, as well as performing exceptionally well even in fully submerged scenarios, Sylomer, Sylodyn and Sylodyn HRB materials have been developed to provide a complete maintenance free solution to building isolation.

In situations where the vibration source is very close to a buildings foundation, or when the isolation requirement is particularly high, it may be necessary to have a lower natural frequency for the isolation system of < 3.5Hz. This is often the case for concert halls or cinemas such as the Bridgewater Hall in Manchester and the BFI IMAX Cinema in London.

TVS, utilizing pre-stressed GERB spring units, are able to provide this very high performance isolation along with offering the close support and technical knowledge required, to integrate these bearings into the structural design.
