Post-tensioned girders with internal and external tendons are widely used for the
construction of bridges because of their eminent advantages. However, owing to poor grout …

This paper investigates experimentally the feasibility of estimating the stress in the
prestressing tendons of prestressed concrete bridges using the magnetic field induced by an …

Reinforced concrete structures undergo various degradation processes, mainly rebars
corrosion. Recently, magnetic non-destructive tests have been used to study the steel …

Defects in steel reinforcement are critical factors in the evaluation of the service life of
reinforced concrete (RC). Steel reinforcement (bar) defects or deterioration may lead to …

Magnetic methods are progressing in the detection of corrosion in prestressing strands in
adjacent precast, prestressed concrete box-beam bridges. This study is the first field trial of …

This paper describes the development of a magnetic sensor system for the evaluation of the
condition of prestressed strands inside the bottom layer of concrete box beams. The sensor …

This work presents a novel computer model which simulates the main magnetic flux (MMF)
signal of prestressing strand subjected to a magnetic field. Magnetic inspection techniques …

Sustainability, reliability, and safety of complex industrial infrastructure are crucial worldwide
issues. Long-term sustainable life quality, services and economic growth provided by …

Technical challenges exist with infrastructure that can be addressed by nondestructive
evaluation (NDE) methods, such as detecting corrosion damage to reinforcing steel that …

Carbon steel is an important component in reinforced concrete structures. These composite
materials are susceptible to various degradation processes, especially the corrosion of steel …
