Fibre-Cement Panel Ventilated Façade Smart Control System.

Area of Science:

• Materials Science
• Structural Engineering
• Non-Destructive Testing

Background:

• Fibre-cement panels are widely used in ventilated façades.
• Assessing the mechanical integrity of these panels, especially under load, is crucial for structural safety and performance.
• Existing methods may be destructive or lack real-time monitoring capabilities.

Purpose of the Study:

• To design a smart control system for fibre-cement panel ventilated façades.
• To utilize the acoustic emission (AE) method for monitoring material behavior.
• To develop a non-destructive methodology for assessing variations in mechanical parameters.

Main Methods:

• Samples of full-size fibre-cement panels were subjected to three-point bending tests.
• Acoustic emission (AE) signals were acquired during the tests.
• AE signals were statistically classified into four classes using the k-means algorithm, correlating them with material processes under load.

Main Results:

• Distinct characteristics and temporal distributions were identified for different AE signal classes.
• The k-means algorithm effectively classified AE signals related to material processes.
• The study demonstrated the applicability of the AE method for assessing mechanical variations in fibre-cement composites.

Conclusions:

• The acoustic emission method is applicable for assessing variations in the mechanical parameters of fibre-cement panels.
• A novel methodology for non-destructive assessment of fibre-cement panel mechanical properties was developed.
• The proposed smart control system offers a viable approach for real-time monitoring and integrity assessment of façade systems.
