On Implementing an Irreducible Element Model Schema for Population-Based Structural Health Monitoring

Abstract

This paper is the second in a series in which the aim is to provide an underlying database technology for enabling the user interaction required for Population-Based Structural Health Monitoring (PBSHM). In the first paper in the series, the groundwork was laid for a PBSHM Schema which enabled the storage of channel data via a Time First approach. PBSHM considers grouping similar structures together to gain additional insights from the group, compared to a single entity. Part of the PBSHM process is being able to identify which structures, or substructures, are similar. To enable this a standardised method of representing each structure must be used; here, an Irreducible Element (IE) model is employed. This paper builds on the groundwork that has been laid in the creation of IE models and defines a standardised format and properties for an IE modal to enable graph matching algorithms to find similar structures. The standardised format has been implemented via an IE-model Schema within the PBSHM Schema.
