【 摘 要 】

The current period in the development of building industry can be characterized as a period of rapid development in this field, not only in the area of new constructions, but also in the area of a new uses of old constructions which find a new use after restoration, and as regards traffic facilities, especially bridge structures, in the area of verification of the existing functional characteristics and prediction of the lifetime of structures. This puts a strain on the field of diagnosis of structures, the development of which can be observed in the last 10 years in the form of a new wave of innovations of the existing NDT (non-destructive testing) methods as well as of the development of completely new devices and technologies. In spite of these facts, it can be said that in a number of cases, the diagnosis of structures is performed in traditional ways without using modern techniques and technologies. The aim of this paper is to present an optimal way of using NDT methods in the diagnosis of reinforced concrete beam structures, specifically in the determination of the position of shear bends on the main load-bearing reinforcement. The paper deals with the current state of the issue and illustrates, on a number of examples from practice, the applicability of individual methods as well as their limitations given by their physical principles and technological solutions.
