METHOD AND DEVICE FOR MONITORING SOUNDNESS OF STRUCTURE

摘要

PROBLEM TO BE SOLVED: To perform an inclusive inspection from overall damage to local damage of a structure. SOLUTION: PZTs (piezoelectric elements) 2 (2A, 2B, and 2C) are adhered to joint parts of a steel skeleton of a steel skeleton structure 1. Electric signals from the PZTs 2 are connected to a data processing part 4 via a multiplexer 3. The data processing part 4 is provided an oscillation mode analyzing part analyzing an oscillation mode of the structure 1 from the electric signals generated by the PZTs 2 in accordance with an oscillation of the structure 1 and an electrical impedance measuring part. measuring electrical impedances of the PZTs 2.
