The knowledge of the dynamic state and structure of system allows to describe its behavior, and allows a model of the system behavior in the function of dynamic evolution time, based on the model of the technical state symptoms growth. Most often, there are no known equations describing behaviors of the system in the function of dynamic evolution time, which accounts for the need to apply new tools to examine the dynamic state. In this article authors shows chosen problems of technical state diagnosis with the use of identification and technical diagnostics methods such as experimental modal analysis. Relations between methods of dynamic state evaluation and methods of technical state evaluation were indicated. Example modal analysis results illustrate the complexity of projecting dynamic state researches into diagnostic researches of state evaluation.

Evaluation of degradation of bricks using FRF


Innovative buildings and structures as a means of humanization of urban space are considered. Innovative buildings and structures are designed for various processes of human life. Innovative buildings are the objects of technologies, where the latest achievements in various fields of science and technology are realized. They were created gradually in the process of civilization development, but at all the stages of historical development they were distinguished by their novelty (they didn’t have analogs), their unconventional constructive and compositional space-spatial solution which provides the individual artistic image of the object. These buildings should be differentiated into historical and modern. At each stage of historical development, they were architectural objects with new qualitative characteristics. The main patterns in the formation of innovative historical and modern objects are identified. The application of the phenomenological concept in the design of innovative buildings, when the architectural environment acquires its properties depending on the spatial – physical and utilitarian – needs of a human, where a person is viewed as a functioning object, as well as spiritual-aesthetic needs, where a person is considered as a perceiving subject, becomes urgent. The aspects of the humanization of the urban environment that innovative buildings should fulfill are determined.
