Wireless Network for Assessing Temperature Load of Large-Scale Structures Under Fire Hazards.

Area of Science:

• Structural Engineering
• Fire Safety Engineering
• Wireless Sensor Networks

Background:

• High-rise buildings face significant risks from structure fires, potentially leading to failure or collapse.
• Assessing structural integrity during and after fires is crucial for safety.
• Existing wireless temperature monitoring solutions lack real-time load redistribution assessment.

Purpose of the Study:

• To propose a novel framework using temperature sensors and wireless communication for monitoring large-scale structures during fires.
• To develop user-friendly hardware and software for effective fire load measurement.
• To enable real-time assessment of structural integrity and load redistribution.

Main Methods:

• Development of a framework integrating temperature sensors and wireless communication technology.
• Careful selection and development of associated hardware and software components.
• Validation of the framework's autonomous measurement system in a fire testing laboratory using a real-scale steel column under standard fire conditions.

Main Results:

• The framework successfully provided autonomous measurement capabilities.
• User-definable sampling frequencies based on surface temperature were achieved.
• Real-time assessment of load redistribution due to fire loading was demonstrated.

Conclusions:

• The developed framework shows great potential for real-time structural fire monitoring.
• It allows for more accurate estimations of fire load in design criteria.
• The system advances the field of fire safety engineering by providing critical real-time data.
