Signal-Processing Procedure for Preliminary Concrete Anomaly Screening Based on Continuous Sliding Acoustic Excitation

Internal discontinuities in concrete walls are hidden conditions that can compromise local structural capacity and durability. Rapid and objective on-site anomaly screening is therefore important for structural integrity evaluation. This paper presents a signal-processing procedu...

Experimental Study on the Identification of Impact-Induced Secondary Damage Inside Concrete Based on Multi-Domain Vibration Signal Indicators

A large number of in-service concrete components in infrastructure are prone to internal secondary damage, which seriously threatens the long-term safety of structures. To effectively identify internal secondary damage in concrete structures and reveal the influence of cracks on...
