Whole Body Vibration in Buildings

Building WBV by SINUS Messtechnik GmbH

Soundbook/NoisePAD/Apollo Boxes/Apollo PCIe Card +  Tri-axial/Uniaxial seismometer or accelerometer + SAMURAI + Option: HVMA or Building Vibration

Whole body vibration levels for human comfort in buildings or building structures may be measured using four channel data acquisition systems by SINUS Messtechnik GmbH (Soundbook/NoisePAD/Apollo Box/Apollo Lite/Apollo PCIe Cards), a floor mounted tri-axial or uniaxial seismometer, or a triaxial or uniaxial accelerometer and SAMURAI Software Options as follows:

Hardware: Soundbook 4ch, NoisePAD, or Laptop + Apollo Box 4ch, or Laptop +Apollo Lite 4ch, or desktop computer + Apollo 4ch PCIe Card

Software: SAMURAI 4ch software, Options: Building Vibration and/or HVMA

Transducer options:

Seismometers – Floor mounted tri-axial or single axis (horizontal or vertical)  (1 to 80Hz or 1 to 315Hz upper frequency limit)

or

Accelerometers – Floor mounted tri-axial or single axis (horizontal or vertical) (600Hz upper frequency limit)

Standards

DIN 4150-2: Vibrations in buildings – Part 2: Effects on persons in buildings

Field of Application:

During construction works in cities and industrial areas, control of vibration levels in adjacent building spaces is very important to protect human comfort.  The high building density that occurs in cities and the constant redevelopment of building sites may cause occupants of residential and office buildings to be potentially adversely impacted by vibration levels resulting from demolition or construction activities that occur in the vicinity.

Similarly, on industrial or mining sites, control rooms and other occupied rooms may be adversely impacted by vibration from nearby material processing activities.

Description:

The SAMURAI  Building Vibration or HVMA Options enable the measurement and analysis of building vibration according to DIN 4150 for the purpose of the evaluation of its effects upon buildings and structures, as well as people within them, using the Apollo family of multi-channel data acquisition devices (Soundbook/NoisePAD, Apollo Box/Apollo Lite/Apollo PCIe Card).

Upon the occurrence of vibration, a marker is set in a vibrational velocity/frequency diagram at the position determined by the relevant frequency and the maximum velocity from the three axes.

The guideline values for vibrational velocity in foundations of commercial buildings, housing and protected historical monuments are also shown graphically in the diagram.

The vibration levels may therefore be assessed in real-time during a measurement to indicate whether and how often the threshold values for the relevant building type were exceeded.

For evaluating the effects of vibration upon people in buildings, the SAMURAI  Building Vibration Option provides the maximum level in consecutive time intervals of the frequency-weighted vibration signal, KB(t). The length of the time intervals is freely selectable.
