Development of Damage Indicators: We implement state-of-the-art algorithms to develop advanced damage indicators, extracting critical information for predictive maintenance and proactive asset management.

WHAT DOES IT MEASURE?

Deformations: We use sub-millimetric measurements to provide insights into how a structure responds to various loads, such as traffic and weather conditions. By analyzing the data over time, we assess the structure's behavior through coherence with historical trends.

Dominant Frequency: The frequency at which the maximum vibration value occurs in the respective spectrum, corresponding to the direction in which the vibration signal amplitude in time is maximum.

Maximum Velocity or PVS (Peak Vector Sum): The maximum vibration velocity during the period in which the recording takes place, considering the same moment in time. This indicator allows the verification of potential damage due to external events (e.g., wind) by checking vibration limits set in the NP2074:2015 standard and DIN 4150-3. These standards establish criteria for limiting the values of physical quantities characteristic of impulsive vibrations with a limited number of occurrences, aiming to prevent damage (originating from such dynamic solicitations) in structures.

ONLINE DAMAGE INDICATORS

Modal Frequencies (or Natural Frequencies) Extraction and Tracking: Modal analysis is one of the most commonly used methods to characterize the performance of structures. Structures such as towers or buildings have multiple natural frequencies that depend solely on their stiffness and mass. Continuous monitoring of these frequencies allows the detection of changes in structural behavior.

Maximum Velocity or PVS (Peak Vector Sum) Tracking: Automation of risk alerts based on the thresholds defined in DIN and NP standards.

Deformation Tracking: Implementation of probabilistic thresholds (quantiles) to monitor trends in structural behavior.

Infodynamic Data Analysis Evaluation of the evolution of the Shannon Measure of Information (SMI), which quantifies the amount of information present in the signal, measured in nats (the natural unit of information). An increase in SMI indicates growing uncertainty in the data, while SMI values close to zero indicate high predictability. Sudden changes in SMI values suggest structural changes caused by external events and/or damage.

WHO USES MATEREO

Infrastruture Operators: Ensure the safety, reliability, and longevity of critical assets such as bridges, towers and buildings. By continuously monitoring structural behavior through sensors and advanced analytics, SHM helps detect early signs of damage, optimize maintenance schedules, and comply with safety regulations. This data-driven approach reduces operational risks, prevents costly failures, and enhances decision-making for long-term infrastructure management.

Maintenance Contractors: Optimize workforce planning and resource allocation. Real-time data helps schedule maintenance efficiently, reducing unnecessary inspections and ensuring teams focus on critical issues. This improves safety, efficiency, and cost-effectiveness.

Engineering and Consultancy Companies: Assess the structural condition of assets to identify maintenance needs and requirements.
