Diagnosis and monitoring of buildings.
ISAAC offers a non-invasive, precise and low installation time system for the diagnosis and monitoring of buildings, which increases the reliability of structural analyses. It is applicable both on masonry, reinforced concrete and steel buildings.
The diagnosis and monitoring of buildings system is mainly constituted by: vibrodines, installed on the top floor of the structure, and sensors distributed outside the building.
1) Building conditions diagnosis and identification of any structural damage
2) Building computer model updating
3) Information in output useful to perform the seismic vulnerability analysis
4) Continuous monitoring for damages identification with integrated warning system
and detailed results
Analysis of the overall behaviour of the building either in masonry, reinforced concrete or steel
Analysis of the structure behaviour with and without cladding if framed
Structure diagnosis thanks to the FEM model creation and updating
Rapid post seismic evaluation
for usability analysis
Low invasiveness and no need to shut down the building
Personalised offer (Diagnosis or Diagnosis+Monitoring)
Diagnosis and monitoring of bridges.
the product offered by ISAAC consists of a modular monitoring system for motorway bridges, independent for each span, which uses integrated hardware and software, with high computational complexity. Processing data directly on site reduces costs and relative time to manage all data in the Cloud, collected thanks to the extensive network of accelerometric sensors. This type of dynamic monitoring makes it possible to promptly identify the presence of possible damage in each span and gives indications of the damaged beam region (example: cracks). If coupled to a FEM model of the bridge, it allows to carry out a first diagnosis for the identification of possible areas with localized stiffness decrease to have an image of the bridge health condition.
1) Continuous infrastructure monitoring and alert system
2) Data processed directly on-site decreasing cloud costs and simplifying data interpretation
3) Possible initial diagnosis and creation of the “day zero” infrastructure model
and detailed results
Infrastructure diagnosis thanks
to the FEM model creation
Low cost system, thanks to the use of a network of accelerometers and on-site data processing
Seismic protection ISAAC-AMD.
ISAAC-AMD is a smart active device for the seismic protection of existing buildings, consisting mainly of an inertial mass moved by hydraulic mechanisms. By discharging forces on the top floor of the structure, it counteracts the movement of the building by reducing its amplitude of oscillation thanks to the remarkable damping increase.
RESULTS: The tests carried out on the ISAAC-AMD scaled prototype, thanks to the use of a shaking table, recorded a reduction of the oscillation amplitudes between the base and the roof up to 8 times. It was therefore proved that the damages to the structure, in case of an earthquake, were significantly reduced thanks to the use of the ISAAC-AMD device
HARDWARE: the seismic protection system is constituted by the ISAAC-AMD device (number of devices varies according to the structure typology) and sensors installed outside the building.
INSTALLATION: non-invasive installation on the top floor of the building or in the attic.
Patent pending device (number: 102018000007173)
Multiple arrays of the same device (Make To Stock)
Possibility to obtain the seismic improvement required by the client
Continuous structure monitoring
Resident comfort and safety is guaranteed
Rapid and non-invasive
Does not require the eviction of the tenants from the bulding
ISAAC carries out dynamic analyses of structures and infrastructures (buildings, bridges, pylons, cables, wind turbines, …) in order to extract the modal parameters of the analysed object: natural frequencies, damping and vibrating modes. Instruments are used for all types of applications, with sensors ranging from piezoelectric accelerometers with sensitivity 10V/g up to MEMS accelerometers with high full scale.
The analyses can be carried out using forced vibration techniques (dynamometric hammers, vibrodines, …) or using environmental disturbances (wind, micro earthquakes or traffic).
