abstract = "The repair of structural elements for the prestressing of reinforced concrete is necessary
when existing prestressing wires are damaged or after a certain period of time. The objective of this
paper is to describe the methodology for the life assessment of corroded prestressing wires, sampled
from prestressed concrete elements after a few decades of use. The aim of the presented research was
to determine the real properties of corroded wire in terms of the evaluation of remaining load capacity
using the Theory of Critical Distances (TCD). The methodology also includes spatial 3D characterization
of corroded surfaces, determination of mechanical properties, and Finite Element Analysis (FEA)
of a model of wire with corrosion pits. The final goal of the presented methodology is to enable more
efficient evaluation of repair range and options for the elements of mechanical prestressing systems
within various structures. The results and conclusions indicate that the developed methodology,
based on the interdisciplinary approach and implementation of state-of-the-art methods, has a high
applicability potential for both static and fatigue fracture prediction in the case of prestressed wires.
The proposed method has a huge potential for simple and fast prediction of the life assessment of
engineering structures, particularly for damaged elements with arbitrary geometry features",
