Structural Health Monitoring, 2023
Monitoring the prestress of prestressed concrete structures is hard but helpful. The resonance-enhanced magnetoelastic (REME) sensor could measure the stress of steel, but the measurement is influenced by the stress history.

Monitoring of prestress and bond stress of self-sensing FBG steel strand
, 2021In order to investigate the stress distribution in a prestressed steel strand and the development of bond stress between the steel strand and concrete, a new technology of encapsulating quasi-distributed fiber Bragg grating (FBG) sensor in a longitudinal

Strengthening prestressed concrete with prestressed CFRP
Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, 2009This paper presents the effect of unevenly prestressed carbon-fibre-reinforced polymer (CFRP) sheets used for strengthening a prestressed concrete beam (L = 3·6 m). An integrated anchor system, consisting of steel brackets and anchor plates, is used to prestress the sheets.

Concrete cracking prediction under combined prestress and strand corrosion
Structure and Infrastructure Engineering, 2019This study investigates strand corrosion-induced concrete cracking under various prestress experimentally and analytically. Experimental data on the critical time of cover cracking, crack width and corrosion loss obtained from the accelerated corrosion ...

Structural Concrete, 2003
The idea of prestressing—a product of the twentieth century—has announced the single most significant new direction in structural engineering of any period in history. It put into the hands of the designer an ability to control structural behaviour and, at the same time, it enabled the designer—or forced the designer—to think more deeply about the ...

Identification of prestress force in a prestressed Timoshenko beam
Structural Engineering and Mechanics, 2008This paper presents a new identification approach to prestress force. Firstly, a bridge deck is modeled as a prestressed Timoshenko beam. The time domain responses of the beam under sinusoidal excitation are studied based on modal superposition. The prestress force is then identified in the time domain by a system identification approach incorporating ...
