Buildings are designed to withstand vibrations from passing trucks, traffic, railroads or subways.
To protect your building, assets, bridges, tunnels etc. the DIN4150 recommends maximum values to prevent damage.
Profound VIBRA is measuring in compliance with the DIN4150, DIN4150-3 80Hz and BS7385 250 Hz.
|Type of structure||Guideline values for velocity|
in mm/s in horizontal plane of the
highest floor, at all frequencies
|Buildings used for commercial purposes, industrial buildings|
and buildings of similar design
|Dwellings and buildings of similar design and/or occupancy.||5 mm/s|
|Structures that, because of particular sensitivity to vibrations are not classified|
as described as buildings or dwellings and are of great intrinsic value, for
example listed buildings under preservation order
|Place||RMS – PEAK||Limit at 20 Hz||Acceleration|
|Structural Integrity DIN4150||Peak||10 mm/s||1.26 mm/s2|
|Machine Service AS2625||RMS||1.8 mm/s||0.23 mm/s2|
|Human Comfort AS2670||RMS||0.1 mm/s||0.1 mm/s2|
|Damage type||Probability 5%||Probability 50%||Probability 100%|
|Treshold value for cosmetic damage e.g. cracking of untaped|
|13 mm/s||64 mm/s||228 mm/s|
|Minor damage: loosening of plaster and hairline cracks in|
plaster and in masonry around openings
|46 mm/s||127 mm/s||406 mm/s2|
|Onset of structural damage affecting load support elements||64 mm/s||152 mm/s||430 mm/s|
