Austrian Standard

ÖNORM S 9020

“Building Vibrations”


ÖNORM S 9020Din 4150, 01 - 03


The Austrian standard ÖNORM S 9020, August 1986, Building Vibrations, blasting vibrations and comparable immissions of impulse shape, prescribes guidelines for measurement and placement of geophones station in buildings.

The standard is divided into four sections of assessment :

*


ÖNORM S 9020Din 4150, 01 - 03


The standard is concentrated on a distance – charge relation for 2 areas, which is to be calculated by the following 4 formulas:

Step 1 : Distance – Charge Relation


ÖNORM S 9020Din 4150, 01 - 03


D = shortest distance

L = maximum charge per delay

1) Distance more than 50 m

2) Distance between 15 m and 50 m

under normal conditions


ÖNORM S 9020Din 4150, 01 - 03


D = shortest distance

L = maximum charge per delay

3*) Distance more than 50 m

4*) Distance between 15 m and 50 m

under favourable conditions


ÖNORM S 9020Din 4150, 01 - 03


Step 2: Vibration Measurements

Measurements have to be on this side of building where vibrations are

induced.

Free-field measurements or measurements next to buildings are not

suitable. The measure-system must show a distort-free frequency of

2 - 250 Hz.

The decisive criteria of assessment is the resultant vector sum of the

peak particle velocity, vR,max .

Evaluating Structure Classes

For an assessment on structures the vibration resultant vector sum will be placed into a standard classification table that concludes a building standard design of static stability.


ÖNORM S 9020Din 4150, 01 - 03


Step 3 and 4:

- seismic refraction supported vibration measurements -

experts must carry out determination of stresses.


ÖNORM S 9020Din 4150, 01 - 03


From the above as background in technical sight it can be noticed that the

ÖNORM S 9020, Building Vibrations, from 01. August 1986, was for a

long term a regulation corresponding to the „the rules of techniques“.

General goal of the ÖNORM S 9020 is the protection of buildings from

damage initiated by external short-time impulse-shape vibrations.


ÖNORM S 9020Din 4150, 01 - 03


The ÖNORM S 9020 prescribes that those vibration-measurements there

have to take place where the vibrations enter the building, by meaning on

foundation next to the building side where the immission enter.

Thereby the normative assessment value is the maximum resultant

vibration velocity (maximum vector sum vR,max).

However the influence of frequencies in the standard is considered in two

steps only (range until 50 m and range over 50 m).


ÖNORM S 9020Din 4150, 01 - 03


Including experiences of the last decades the Austrian standard can – in a simplified

investigation procedure of short-time vibration assessment – be used. But, latest

technical/medical discoveries regarding the annoyance of humans in buildings

during short-time vibrations are not objectively given.

Most of the other European countries use frequency-related

standards whose results are appropriately and accurately related to

tectonically requirements of disrupted underground.


ÖNORM S 9020Din 4150, 01 - 03


In the past years it was exposed by accepted (international) scientific and technical

discoveries, that not a vibration velocity based on the 3 single-components x, y und z

and its maximum resultant vibration velocity (maximum vector sum vR,max) has been

conclusively for an assessment, but the peak particle velocity (maximum value vi,max)

from one of the three single-components (x,y,z) on foundation must be observed.

and

which timing is not suited generating resonance at an affected building (facility).

In Germany it is common to use an equation, which gives blasters an idea of the structural related perception in regard to human beings.

Vibration effects will be assessed by a KBFmax value. It is calculated from peak particle velocity vi and its accompanied frequency.

Numerous vibration velocity measurements have provided the empirical

values given guidance on short time structural vibration evaluation.

They shall be based on the maximum value vi,max (maximum vibration

velocity of x, y or z axes) at the foundation.

Also x and y axes vibration of the uppermost floor provides significant

information for the evaluation.

values is unlikely to occur. If, however damage is found, it is to be assumed that

other causes are responsible for this damage.

Conclusion


ÖNORM S 9020Din 4150, 01 - 03


The three parts of the German Standard „DIN 4150, Vibrations in

Buildings“ must be seen and used as one unity.

By following the relatively strict standard it is known that under attention

of their definitions an increased fairness as well as for companies and

for the neighborhood is given.

Besides, it weighs in favor on judicial disputes, which might occur.

Conclusion


ÖNORM S 9020Din 4150, 01 - 03


Conclusion

significant parts from DIN 4150 “Vibrations in Buildings” are adopted to

Swiss Standard SN 640 312a

Austrian BGBl. I Nr. 113/2006

last but not least:

Also the standard or parts of it are applied e.g. in Croatia, Italy, Israel, Slovenia and USA (subway-construction New York) and some other countries.
