The last ten years have seen a rapid growth of research related to the development of methods of localization of defects and assessment of technical condition of metal structures based on dynamic analysis. This paper presents the results of a study on the localization of defects arched steel truss. The main purpose of this article is to analyze the results of the damage index method and the development of the software module to localize structural damage. The results of numerical experiments presented in this article have shown the effectiveness of this method of localization of damage. The use of this method in practice will reduce the time of inspection by pre- defining a site design that are necessary to pay special attention during the field study.
