Anchorage capacity of corroded smooth reinforcement bars in existing reinforced structures.
Paper in proceedings, 2018

Concrete structures are strongly affected by reinforcement corrosion, the most common cause of deterioration.
Most studies on structural effects of corrosion rely on artificial methods to obtain a corrosion
level that would otherwise require years, but doubts on the soundness of the methods have been raised.
Specimens taken from existing structures offer the chance of studying the effect of natural corrosion,
however the choice of the test setup is challenging. Hence, pilot tests are carried out to investigate the
optimal design for testing the anchorage capacity of specimens with smooth reinforcements. The outcome
is an asymmetrically supported 3-point bending beam test. The benefits of using complementary
tools as Digital Image Correlation (DIC), Non-Linear Finite Element Analysis (NLFEA), pull-out tests
and tensile tests and 3D scanning of the bars are presented.
