Aspect Ratio–Dependent Percolation and Strain-Sensing Behavior of Polyurethane and MWCNT Nanocomposites for Real-Time Health Monitoring of Seismic Isolation Bearings

Abstract

AbstractLaminated polyurethane elastomeric bearings (LPEBs) in bridges are susceptible to interlayer delamination and other hidden damage given large deformations or fatigue loading, compromising long-term safety. To address this, this study developed a ...
