Structural monitoring during, and sometimes following, jacking operations is an incredibly important part of any safe load transfer process.
Monitoring determines whether the correct load is being applied to the structure and, just as importantly, how the structure is behaving following the application of load. For this reason, the application of load is normally performed in stages to ensure the structural behaviour is consistent with the design engineers’ intent and understanding.
MONITORING IS TYPICALLY PERFORMED IN TWO WAYS:
A) Monitoring of load
Load monitoring is primarily performed by calibrating the equipment used to apply load.
B) Monitoring of displacement
Displacement monitoring is also critical if the structure’s behaviour under load is to be fully understood.
This will include the additional stroke in the jacking system and other parameters, such as the movement of associated load-bearing elements during the loading or unloading event.
Such monitoring cannot only be performed by surveyors or others with optical levelling equipment, although this may form part of the overall monitoring solution.
Typically, due to the very minor staged movements being measured, the digital measuring equipment will be required to measure to a level of accuracy of 0.01mm. In most situations, only then can you see and predict trends in behaviour as loading is being performed.
If required, we can also provide remote and ongoing wireless monitoring for load and displacement.
Heavy lifting and monitoring projects are particularly diverse, and our experienced team would be happy to discuss your project requirements with you and demonstrate the value that Slabtec can deliver.
