Dynamic and Static Monitoring

 

The OSMOS monitoring equipment records both dynamic and static structure behaviour at the same time continuously.  Other technology records data incrementally at fixed time steps.  This does not give a complete picture of the actual performance of the structure since there may be a significant structural response between fixed time steps which would be missed by other technology.  OSMOS monitoring equipment records data at a frequency of 100 hertz (100 times per second).


Due to a lack of suitable process technology, insufficient consideration has been paid to the time factor during monitoring of structures. Time cycles such as seasons, weekdays, daytime, night time, high and low tides, drive-shaft rotation and natural oscillations show a mark on the structure. These cycles can range in duration from a few fractions of second to several years, and usually overlap.

 

The OSMOS system is the first of its kind to permit complete and continuous structural diagnostics: It registers the entire history of a structure to allow comprehensive analyses. This is achieved through continuous recordings of static and dynamic stress cycles such as tensions, deformations and displacements. Even in the event of a power failure, the integrated reference variable prevents a loss of orientation; thus permitting a correct resumption of recording of measured data following a restoration of power.

 

Sporadic measurements on structures provide data at ‘apparently’ important points in time. These random data acquisitions are used as a basis for drawing conclusions which can be highly erroneous. Consequently, this type of data acquisition is not suitable for reliable forecasts concerning structural behaviour.

 

Knowledge of the entire history of a structure makes it possible to identify and analyze periodic events. This permits a better evaluation of the acquired data. As the period of observation lengthens, an increasing amount of knowledge becomes available to the user, thus resulting in a continuous learning curve. This allows qualified forecasts of future structural behaviour as well as precise risk estimates. Structures can be observed objectively.

 

Only a continuous monitoring of structural loads and stress cycles reflects actual structural characteristics.
