Overview
S2-SHM is the software specifically developed for continuous and fully automated monitoring of relevant physical
and mechanical parameters and, in particular, of the modal properties of structures.
S2-SHM is based on a proprietary algorithm of automated Operational Modal Analysis and state-of-the-art data processing
procedures of statistical pattern recognition and anomaly detection validated in the context of academic research.
The proprietary algorithm is able to automatically process structural vibration measurements yielding the time series of the
dynamic properties of the monitored structure (natural frequencies, damping ratios, mode shapes) useful to assess its health state.
The software is powerful and versatile, and already fulfilling the requirement of the most recent Italian codes in the field of Structural Health Monitoring.
Which problem does it solve?
S2-SHM is a complete software for data-driven Structural Health Monitoring.
You will learn from data if your structure is still in a healthy state, or it is undergoing damage or degradation phenomena.
S2-SHM is the solution you were looking for to automatically process the large amount of data collected by continuous,
vibration-based SHM systems, thanks to its robust engine for automatic modal parameter estimation and the advanced novelty
detection procedures based on statistical pattern recognition.
And if you are interested in monitoring the tensile load in cables and/or tie-rods, S2-SHM also has a specific data
processing module that fits your needs, letting you to monitor the axial load by means of simple and non-invasive
vibration measurements.
Last but not the least, if your SHM system includes dynamic as well as static measurements,
you can manage both data type with the same software, getting the most from the collected data.
Which needs does it fit?
S2-SHM is designed to fit the needs of continuous monitoring of structures, it being able to timely detect anomalies in the
structural response while saving transmission band thanks to the significant data reduction obtained from automatic
data processing.
Thus, you can use S2-SHM to develop effective edge computing systems for continuous, on-line monitoring of structures.
S2-SHM is the must-have software for civil SHM applications!
What makes our software stand out from the competition?
S2-SHM is one of the few commercial software offering an effective procedure for automated OMA,
validated in the context of academic research, and state-of-the-art tools for compensation of the influence of
environmental and/or operational effects and for anomaly detection;
in addition, the software holds procedures for
tensile load monitoring in cables and tie-rods, and it is able to alert remote users in case of detected anomalies.
As a result, S2-SHM is a leading software for an effective and complete data-driven Structural Health Monitoring.
Other strengths
Validated in the context of academic research, S2-SHM has been already adopted by several Italian Universities
and Research Centers; moreover, the software is already compliant with the Italian DM 204/2022 and the IOMAC Guidelines
for OMA in civil engineering.
Technical support is available in English and Italian.
On-line and Off-line
S2-SHM can work either in on-line or off-line mode.
In the former case, S2-SHM should be considered as a part of an edge computing system close to the monitored structure
for automatic analysis and/or data reduction.
In offline mode it can be used to develop multiple analysis projects on a discrete basis.
Input geometry
S2-SHM has drawing tools for a quick input of structural model and test layout. Simplified import of models in .dxf format is available, too.
You can manually input the geometry of your model through the software interface to define:
- the node coordinates (Node);
- connections by one-dimensional type elements (Connection);
- measured degrees of freedom (DOF) in the test model;
- dependency relationships between instrumented (Master) and non-instrumented (Slave) nodes;
- interpolation rules for non-instrumented nodes;
- graphic properties of displayed elements.
In addition to the manual input of model geometry, this can be directly imported from a .dxf file created with a CAD program by following a simple guided procedure. ~FIGURA 28 PAG. 33 MANUALE S2-SHM ITA V.1.2.0~
Input data
S2-SHM supports many common file formats for data loading. S2-SHM also supports the Dewesoft *.dxd file format.
If a file recorded by the S2-DDA (link) software is loaded, also relevant test metadata, such as sampling frequency,
hardware features, channel nomenclature, and data acquisition setting parameters, are automatically imported.
S2-SHM can also retrieve data from an appropriately defined measurement database (for instance, a MySQL database)
by providing the requested ODBC information (please, refer to the manual for more details).
Automated OMA
S2-SHM holds a proprietary procedure to carry out a fully automated Operational Modal Analysis for vibration-based
Structural Health Monitoring applications.
The algorithm for automated OMA has been extensively validated in the context of academic research and it has been
already applied to continuous monitoring of several civil structures, including bridges, heritage buildings,
historical masonry belfries, and hospitals.
The automated OMA feature in S2-SHM returns the time series of the modal properties of the monitored structure
by processing its vibration response under operational conditions.
The identified modal properties (natural frequencies, damping ratios, mode shapes) can be locally processed according
to state-of-the-art statistical pattern recognition approaches for compensation of environmental effects and anomaly
detection.
As an alternative, the time series of the identified damage sensitive features can be downloaded for separate
off-line analysis with third-party software or with a different S2-SHM license.
In addition, you can visualize the animated mode shapes associated with each automatically
estimated natural frequency value.
Axial load
The automatically estimated modal properties can be also used to obtain indirect measurements of the axial load
in structural members mainly subjected to tensile stress (for instance, cables) from measurements of their vibration
response under operational conditions.
Tensile load continuous monitoring in stay cables for structural safety purposes is the typical application
of this S2-SHM feature.
Static response analysis
S2-SHM can be also used to automatically monitor the static response of a structure, check that it remains within user-defined threshold values, to evaluate relevant statistics and to predict its evolution by state-of-the-art statistical pattern recognition approaches.
Anomaly detection and warnings
State-of-the-art statistical pattern recognition approaches are implemented in S2-SHM to predict the evolution
of the selected damage sensitive feature under varying environmental and operational conditions for anomaly detection.
Based on user-defined threshold applied to the processed data, anomalies in the structural
response can be identified and remote warnings can be sent by email.
Visualization and export
S2-SHM holds many useful visualization tools, such as plots of the time series of the automatically identified modal
properties, plots of animated mode shapes, histograms of monitoring data, and control charts for novelty detection.
Many options are available to fully customize the plots for analysis refinement or enhanced data visualization.
At each analysis stage, you can export any image or plot in the most common graphic file formats for external use.
Data exchange and interoperability
S2-SHM is natively interoperable with all other S2X software.
A full list of supported data formats is here reported:
- Data input: *.txt, *.csv, *.tdms, *.lvm, *.dxd
- Geometry input: *.dxf
- Modal parameter monitoring results: *.txt
- Images and plots: the most common graphic file formats, such as *.png.
In addition, S2-SHM can retrieve data from database (for instance, a MySQL database).
Please, refer to the manual for more details.
