A Sensor-Type PC Strand with an Embedded FBG Sensor for Monitoring Prestress Forces

Sensors, 2015
Prestressed Concrete Wire and Strand (PC) strands are the most used materials to introduce prestress in a Pre-Stressed Concrete (PSC) structure. However, it is difficult to evaluate the final prestress force of the PC strand after prestressing or its ...

Long-Term Characteristics of Prestressing Force in Post-Tensioned Structures Measured Using Smart Strands

Applied Sciences, 2020
The proper distribution of prestressing force (PF) is the basis for the design of prestressed concrete (PSC) structures. However, the PF distribution obtained by predictive equations of prestress losses has not been sufficiently validated by comparison ...
