SHM technology has come a long way โ todayโs sensors are accurate, robust, and capable of continuous monitoring. But thereโs still no international standard for how monitoring data should be analysed or used. However, several good research projects exist (worth reviewing).
๐ค AI has opened up new capabilities:
โข Detecting subtle changes
โข Fast prototyping of visualisations
โข Bridge-specific insights
Still, without standards, thereโs no widely adopted SaaS model for SHM. Each bridge remains a custom case.
So maybe itโs time to think in terms of RaaS โ Research as a Service. Modern tools make ad-hoc, continuous research feasible and necessary.
A future-proof SHM setup could follow this 4-phase process:
1๏ธโฃ Data collection
2๏ธโฃ Standardised analysis & visualisation
3๏ธโฃ Bridge-specific research
4๏ธโฃ Expert interpretation
Phases 1 & 2 can be fully automated (cost-efficient, repeatable).
Phases 3 & 4 are still expert-driven โ but not forever. As FE-models and AI integrate, these too will become more automated.
๐ฏ Eventually, weโll have a closed loop:
Monitoring data โ AI metrics โ FE-model โ Damage localisation
This post series focuses on phase 3: how much can we learn from just one point in a bridge and its movement path?
So far in previous posts, all results are based on 3D movements of a single point. The actual safety decisions in this project were made from stress-based analysis, but this side project explores how far one can go using only spatial displacement โ something I havenโt seen done systematically before.
โ๏ธ Itโs still rough and done in spare time, not a polished product. But weโre actively working toward a standardised method to test on other bridges, including stiffer ones with smaller deflections.
๐ฃ And if the data shows no change? Thatโs good news.
In SHM, no change = no concern โ and thatโs a result worth aiming for.
