ELASTO-PLASTIC DAMPER WITH HEALTH MONITORING SENSOR FUNCTION, AND HEALTH MONITORING DEVICE FOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a health monitoring device which contributes to improve safety of a structure and improvement of livability by performing health monitoring on a structure, while utilizing plastic change of a functional elastomeric elasto-plastic damper as a vibration energy absorbing device when an external force is applied. SOLUTION: In the health monitoring device, a monitoring means detects each of electric resistance values before and after a change of organization of a structural material from elastic characteristic to plastic characteristic when external force is applied to the elasto-plastic damper provided in the structure, and the health monitoring device analyzes them to carry out health monitoring of the structure.
