AI Technical Summary

Technical Problem

Current structural health monitoring methods face challenges in efficiently and reliably detecting sudden changes in civil engineering structures, particularly in inaccessible areas, due to high data volumes and the need for manual verification, which can lead to false positives and require constant personnel resources.

Method used

A real-time analysis method using a three-step condition algorithm with sensors to detect changes by verifying correlation coefficients, signal amplitudes, and mean value differences between sensors, allowing for autonomous data interpretation and reducing unnecessary data storage and manual checks.

Benefits of technology

This method enables reliable real-time detection of sudden structural changes, reducing false positives and the need for manual verification, while minimizing data storage and transfer requirements, allowing for efficient monitoring of large civil structures and machines.

Abstract

A method for real-time monitoring of structural changes on a building, applying a certain number N of sensors that are placed on the monitored building whereas the sensors measure a certain parameter such as strain or temperature. The method provides an algorithm for the reliable real-time detection of sudden structural changes in instrumented building monitoring. For that, a three-step condition algorithm is applied to separate deviating measurement data from critical one. An important advantage is the translation of the measured data to reliable information, i.e. the interpretation and handling of a massive amount of data while reducing the number of both data to be additionally checked and notifications concerning critical measurement results.
