| DIAGNOSTICS - STRUCTURE MONITORING | AREA - RUINED BUILDINGS OR BUILDING PARTS | |
|
APPLICATION TECHNIQUE Main monitoring spots are located through a preliminary
survey, setting a sensors/readers installation and displacement
plan and the most suitable data collection syistem; frequency of
data collection, control length and possible alarm system are then
exstimated.
OBTAINABLE RESULTS - Data tables and graphics. - Conclusive report including structure analysis and interpretation. electronic crack measurer   RELATED DIAGNOSTICS - Structure tests - Finished elements moulding |
DETECTABLE DATA sensors are different in type and function. They can be: - electronic or mechanic - distance measuring (crack measurers), inclinometric, settlement measuring - monoaxial or bi-triaxial - thermo-higrometric Physical data aquisition can be centralized throughinformatic
and telematic data collection and structure dynamics real time analysis
.
 SURVEY - Problems check with designer - Main critical zones location - Building's accessibility and use - Historic and cartographic documentation - Usable thecnological equipement COSTS Assembly, installation and monitoring |
|
Structure monitoring to be carried out
on buildings, monuments, works of art by previous detailed survey
to locate and study static instability's "pathological" aspects,
with electronic sensors dispacement plan (number of thermometers,
crack measurers, deformation measurers, bi- or monoaxial inclinometers,
settlement measurers, piezometers, extensometers. Data collection
system connection. Exstimation of data collection and output frequency.
Instuments assembly and disassembly arrangement. Quarterly and final
report arrangement, with data, graphics and final results analysis)
Systems can be equipped with optic or acustic alarms, forewarning
in case of dangerous failure. Sensor collected data can be transmitted
both by cable or radio device.
