Abstract
The paper presents an experimental and numerical study investigating the effectiveness of two innovative stress sensors (piezoelectric and capacitive) installed within mortar bed-joints for Structural Health Monitoring (SHM).
Highlights
- Two types of stress sensors embedded in mortar joints are tested for real time monitoring of masonry structures.
- Half scaled masonry wall specimens made of three piers were arranged with calcarenite and clay masonry.
- Damage to the central pier was induced during the test by a progressive reduction of the cross-section.
- A numerical micro-model is used as reference for comparison of vertical stress measures.
- Simplified fiber-section equivalent frame modelling is validated as an effective approach for real time monitoring.
