Structural health monitoring is attracting attention as an effective means to understand the functional continuity of a building after earthquake. Previous studies have reported that continuous use buildings was restricted damage their foundation structures despite minor themselves. We propose identify soil springs using subspace method one indirect methods; then, this approach verified via num...

As one of the most common structural forms in port engineering, operation environment high-pile wharf is quite harsh and complex, its pile foundation often produces damage different degrees. Until now, there a lack efficient, safe economic detection methods. A novel precise real-time (SDD) method using both finite element modelling (FEM) 1D convolutional neural networks (CNNs) established this ...

The use of embedded piezoelectric-wafer active-sensors for in-situ structural health monitoring of thin-wall structures is presented. Experiments performed on aircraft-grade metallic specimens of various complexities exemplified the detection procedures for nearfield and far-field damage. For near-field damage detection, the electro-mechanical (E/M) impedance method was used. Systematic experim...
