A Review of Global Navigation Satellite System (GNSS)-Based Dynamic Monitoring Technologies for Structural Health Monitoring

Remote Sensing, 2019
In the past few decades, global navigation satellite system (GNSS) technology has been widely used in structural health monitoring (SHM), and the monitoring mode has evolved from long-term deformation monitoring to dynamic monitoring. This paper gives an

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

Structural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...
