 Summary:
 Detection of cracks in reinforced concrete (RC) beam elements using non-destructive methods is a very demanding task because of physical and mechanical characteristics of the material. Cracking can occur in concrete structures for several reasons that can primarily be grouped into either mechanical loading or environmental effects. Determining the exact cause of the crack, their number, position and orientation is impossible in many cases. Crack detection in RC using piezoelectric (PZT) sensors and based on wave propagation is one of the non-destructive methods (NDM) presented in this paper. Principles and application of active monitoring systems of RC structures are presented in this work. Modelling damage detection methods, using the finite element method (FEM,) are very important for the numerical simulation of this problem.
