What is Structural Health Monitoring?
Structural Health Monitoring (SHM) uses sensors, vibration analysis, and computational models to detect, locate, and assess damage in civil structures like bridges, buildings, and historic masonry in real-time.
SHM integrates non-destructive techniques such as modal analysis and finite element model updating to monitor infrastructure integrity. Key studies include vibration-based assessments on laminated glass (Bedon, 2019, 50 citations) and ancient masonry churches (López et al., 2019, 36 citations). Over 200 papers exist on SHM applications in civil engineering, with citations peaking for stability analyses (D’Altri et al., 2018, 55 citations).
Why It Matters
SHM prevents failures in aging infrastructure, enabling predictive maintenance for bridges and buildings, as shown in tension estimation for Nielsen-Lohse bridges (Furukawa, 2022). Bedon (2019) demonstrates vibration analysis for delaminated glass structures, reducing retrofit costs. Fatigue assessment via finite element models (Mashayekhizadeh, 2019) extends steel bridge lifespans, while in-situ measurements on stone bridges (Manos et al., 2017) inform heritage preservation. D’Altri et al. (2018) highlight stability gains for leaning masonry, cutting seismic risks.
Key Research Challenges
Model Updating Accuracy
Finite element models require precise calibration with experimental data for reliable damage detection. Genç et al. (2022) updated models for İskenderpaşa mosque using in-situ measurements, but discrepancies persist in complex geometries. This limits predictive power in historic structures.
Vibration Data Interpretation
Extracting damage indicators from noisy in-service vibrations challenges SHM algorithms. Bedon (2019) analyzed delaminated laminated glass beams, noting analytical-numerical mismatches. López et al. (2019) simplified frequency formulations for masonry churches, yet damping estimation remains inconsistent.
Sensor Network Scalability
Deploying cost-effective, dense sensor arrays on large structures like bridges faces durability issues. Furukawa (2022) used natural frequencies for cable tension in Nielsen-Lohse bridges, but scaling to full networks increases data overload. Mashayekhizadeh (2019) integrated field data with FEM for fatigue, highlighting integration hurdles.
