5.2 Measuring in accordance with DIN 4150-3
Measurement procedure
DIN 4150-3 is the most widely applied standard internationally for measuring structural vibrations. The
measurement procedure can be found in a similar form in other national standards, for example the Italian
UNI 9916.
The assessment parameter is the maximum value v
i
of the three individual components (peak values) of
vibration velocity at frequencies of 1 to 80 Hz. The measurements are carried out at the foundation.
Vibrations in the ceiling of the upper most outer walls also provide valuable information for analysis.
These detect the horizontal response of the building to the vibration at the foundation. Only the greatest
value of both the horizontal components is then used for the analysis.
The standard provides reference values for permissible vibration velocities for short-time and sustained
vibration in three types of buildings.
-
For massive civil engineering structures, e. g. reinforced concrete constructions for abutments or
block foundations, you can increase the reference values for industrial buildings up to two times.
-
If short-time vibrations occur in ceilings at below 20 mm/s in vertical direction, a reduction in the
serviceability does not have to be expected.
The standard also gives reference values for short-time vibration on pipelines of different types:
Reference values for short-time vibration on pipelines
Pipe material
Vibration velocity v
i
Steel, welded
100 mm/s
Stoneware, concrete, reinforced concrete, pre-
stressed concrete, metal
80 mm/s
Brickwork, plastic
50 mm/s
