    If you are looking for a software system that can help detecting both rapidly and slowly growing damages of
    a structure, then ARTeMIS-SHM probably is the solution for you. Our new vibration-based Structural Health Monitoring (SHM) system can help plan inspections and maintenance of structures more effectively, reducing unnecessary inspections, and you get much earlier notice with ARTeMIS-SHM, comparing with other systems, when the structures dynamic behavior is changing.

    4 reasons to use the new ARTeMIS-SHM

    Our ARTeMIS-SHM solution is a software platform that is designed to perform advanced vibration-based SHM analysis obtained from a range of commonly used data acquisition systems. It has very sensitive algorithms implemented that can extract maximum information from the dynamic measurements. With ARTeMIS-SHM you will get the most out of your measurements.


    Structural Health Monitoring (SHM) is defined as the periodical monitoring and analysis of structural response of a structure to determine whether its material and/or geometrical properties are changing or not.

    Rapidly growing damages occur when a structure has exhibited a severe event, such as an earthquake or ship collision. In these cases, ARTeMIS-SHM can notify if the structure has suffered significant damage that affect the structural performance. The notification can be issued after approximately 30-60 minutes depending on the size of the structure. This is valuable for the assessment of evacuated buildings that otherwise needs physical inspection.

    Slowly growing damage is very dangerous, and the cause for many collapses around the world every year. ARTeMIS-SHM can detect even very small changes of the dynamic behavior of a structure with a high degree of accuracy. This enables engineers to get an early warning when e.g., cracks or corrosion starts affecting the structural performance.

    Our ARTeMIS-SHM software platform is designed to plug into any new, or already installed, data acquisition platform that can stream raw time domain recordings to short time data files. Typically, these short time data files have a duration of 5-10 minutes. ARTeMIS-SHM will then read these files and do the required data analysis, notification, reporting, and web-based presentation.

    Inspections and Maintenance

    An SHM system can help plan inspections and maintenance of structures more effectively, and thus prevent expensive and unnecessary inspections or worse prevent too long inspection interval, which can result in loss of life and property. 

    Reducing unnecessary inspection and maintenance will also help lowering the costs, and at the same time lower the down time required.

    Emergency Response Planning

    In earthquake prone regions many structures can be affected by shaking at the same time. If the structures in the region haven’t any SHM systems installed, inspections are most likely required on all earthquake sensitive structures. Here the bridges along the emergency response routes as well as hospitals etc. are the priority for inspectors. It can be a very comprehensive work for maybe a few inspectors. Since earthquakes typically are followed by severe aftershocks, the inspection procedures in many cases need to be repeated multiple times.

    If SHM systems are installed on the critical structures, then these systems can be used to better plan which structures need to be inspected first and which can wait.

    Many Hardware Suppliers and Consultant Companies

    In general, SHM involves many disciplines and as such you will find many suppliers when you search the internet. Most supplier will be companies producing hardware such as data acquisition system, and static and dynamic sensors. Other companies will be consultant or asset management companies offering their services in perhaps predictive inspection and maintenance. 

    Many of the hardware producing companies will be offering some light-weight analysis software on top of the data acquisition platforms. Light-weight analysis can be various visualization of the measurements and channel statistics, and perhaps simple modal analysis like frequency domain peak picking. There is no doubt that in many cases it is possible to get much more information extracted from the same recorded measurements.

    Strong Motion Analysis and SHM goes Hand in Hand

    In case of seismic monitoring systems, the data acquisition system is often waiting for strong motion events to happen. During these event Strong Motion Analysis as well as Interstorey Drift Analysis are typically conducted. Basically, any data acquired in between events are not used and rejected after having stayed in a ring buffer for some time. This “idle” state data contains valuable information of the state of the monitored structure and is the primary data source for ARTeMIS-SHM long term monitoring tools. ARTeMIS-SHM is as such a complementary tool to any Strong Motion Analysis software. ARTeMIS-SHM also has Strong Motion Analysis tools as well as Interstorey Drift Analysis tools available.  

    At Politecnico di Torino we actively use the ARTeMIS software in our research activities as this software is worldwide recognized as a “state of art” in Operational Modal Analysis. In several cases we use ARTeMIS Modal Pro as the computational engine for structural health monitoring. Most exemplary case is the dynamic monitoring of the new Genoa S. Giorgio bridge, built after the tragic collapse in 2018. Here the ARTeMIS software is integrated into the permanent monitoring system.

    of Structural, Geotechnical and Building Engineering.

    British Columbia Ministry of Transportation and Infrastructure (MOTI) are using the ARTeMIS software platform for the analysis of the bridge seismic data. The advanced tools in ARTeMIS have enabled full automation of large amount of data analysis from multiple bridges in real time.

    ARTeMIS-SHM – Benefits

    With our SHM solution there are several benefits:

    • Get a notification with link to a status report the instant the systems detect a structural change that can be critical for the performance of the structure.
    • Get a quick overview of all monitored structures with color indicators for safe, critical, and unsafe status. An overview dashboard displays the structures and their state either using Google Maps or in different types of list views.
    • Get immediate access to analysis details for closer inspection of what has caused an alert.
    • Share information across the organization using web browser access.
    • Analysis can be configured to run many methods in parallel that joined together deliver highly sensitive results.
      This allows an early detection of damage and at the same time prevent too many false alarms.
    • Multiple structures can be analyzed sequentially by the same license and same computer.

    ARTeMIS-SHM – Technical Overview

    The ARTeMIS-SHM solution leverages on the ARTeMIS Modal Pro platform, that has been the state-of the-art reference software in Operational Modal Analysis for more than two decades. The solution is centered around ARTeMIS Modal Pro but consists of several other components. 

    Data Input 

    Input to the system is the raw time series measurements. These measurements are typically store in fixed length recorder files (e.g., 5-10 minutes files). We support a wide range of file formats used by major hardware vendors. Currently, more than 20 files formats are supported. Some specific formats are:

    • MiniSEED files exported from Guralp Systems Ltd., and GeoSIG AG 
    • EVT files exported Kinemetrics Inc. 
    • VIF files exported from a variety of hardware suppliers. 
    • Text files where channels are stored column-wise, with or without header information.

    Files are read by ARTeMIS Modal Pro which is the data analysis engine of the system and possibly merged to longer recordings for improved analysis results. The data files can be read from any network accessible location like Network Attached Storage, FTP or from the cloud.

    Analysis Engine 

    The analysis engine of the system is ARTeMIS Modal Pro, and optionally with additional SHM plugins enabled. For setting up the projects the graphical user interface of ARTeMIS Modal Pro is used. Once the project and the various analysis methods are configured, then the project is managed by the SHM Automation Service that is a Windows Service. 

    SHM Automation Service 

    The SHM Automation Service can analyze multiple structures sequentially using a single ARTeMIS Modal Pro license. What structures that should be analyzed are configured using the ARTeMIS Modal Pro desktop application. Through the application an XML file is created that contains all necessary instructions for the Windows Service to run. The analyses and the storage of results is made automatically and completely transparent without user interaction. 

    Storage of Results 

    Results are stored in a Microsoft SQL Database that can be located anywhere on the network. The database support storage of results of multiple structures. Results stored are:

    • Geometry and channel information. 
    • For each analysis session, i.e., the analysis of a specific measurement file, the following information is stored:
      • Analysis session information, including references to the measurement files and notifications related to the specific analysis. This includes warnings and errors.
      • Channels statistics: Maximum, Minimum, RMS, Median, Mean, Variance, Skewness. 
      • Modal results of any of the Stochastic Subspace Identification methods available in ARTeMIS Modal Pro: SSI-UPC, SSI-CVA, SSI-PC, SSI-UPCX (Used default). 
      • Modal results stored for each method are: Mode shapes and mode shape complexity. Natural frequencies (mean + standard deviation). Damping ratios (mean + standard deviation).
      • Damage indicator results of any of the damage detection methods available in ARTeMIS Modal Pro: Modal Damage Detection, Classic Damage Detection, Robust Damage Detection, Control Chart for joint damage indicator presentation.
      • SHM overview status values per mode tracked mode and per damage indicator. 
      • Overall health status value (Global Weight Ratio): 100% >= Safe > 90% >= Critical > 50% >= Unsafe >= 0%.
      • Ground motion values for any channel registered as a ground channel: Peak Ground Displacement (PGD), Peak Ground Velocity (PGV), Peak Ground Acceleration (PGA), Katayama Spectral Intensity (kSI), Arias Intensity (Total), Normalized Arias Intensity, Significant Duration of the shaking (D_5_95), The mean period extracted in the frequency range between 0.5 Hz and 20 Hz (Tmean), Modified Mercalli Intensity (MMI), Response Spectrum,  Fourier Spectrum.

    For all analysis sessions the following information is stored: 

    • Mode tracking of reference modes over all analysis sessions. 
    • Thresholds for critical and unsafe levels of the following: Channel statistics. Relative interstorey drift ratios. Tracked modes. Damage Indicators. Control Chart Values.

    Notification Services 

    Users can be notified either by SMS or e-mail or both. The notification is configured through an administration back-office per user and per structure in an organization, and the users can by notified when:

    • A new measurement record has been analysis and new results are available.
    • A structures overall health status changes from being safe to critical or unsafe.
    • Errors or warning are detected during the analysis.

    The notifications will link to reports with information related to the notification type. These reports can be configured through an administration back-office.

    ARTeMIS-SHM – Licence Models

    The specific modules in an ARTeMIS-SHM solution will typically be configured to the individual customer project. The price will depend on factors like the requested functionality, the number of structures to be measured and integration to other predictive maintenance solutions like e.g. IBM Maximo. 

    Traditionally, our customers have acquired it as a PC based license with upfront payment for license including maintenance for three to five years. This license type is most relevant in situations where only ad-hoc measuring and analysis is carried out. 

    Today, and especially for continuous monitoring solutions, we often see that customers request a leased based price model where the investment is split between a lower upfront investment and then a continuously maintenance and support contract over several years to make sure that the solutions is always relevant and up to date.
