Abstract:

Smart City concept is called the concept of the future and it relates to the so-called
intelligent cities. Currently, it is the most promising idea aiming at their development, as well
as to the development of local economy. Smart City is a response to the changes that have been
occurring in the whole world, relating to both expansion and functioning of the cities that
become more intelligent every year. Modern agglomerations should use the newest information
and communication technologies in such a manner that they increase the interactivity
and the effectiveness of urban infrastructure, but also in order to raise the awareness
of the residents. Every city that wants to become smart should include numerous aspects
connected with urban life in its development plan. One of the factors ensuring the effectiveness
of city functioning is Smart Building, which is an intelligent, environmentally friendly
construction, and most of all, it is safe for people. Ensuring the safety of the construction
requires performing a series of diagnostic operations in all phases of construction object's life
cycle. As the result of the influence of external factors on the structure, including
environmental factors, and as the result of useful loads that change during long-time
exploitation, the objects are subject to degradation. Early and precise detection of damages that
occurred during the use allows to take reasonable measures, including repairs, ensuring
uninterrupted exploitation of the object. Therefore, especially in the recent period, a lot of
attention has been paid to the topic of diagnostics and monitoring of the structures being
exploited, and it is connected with the issue of durability and assurance of reliability of these
structures.
The article presents the application of acoustic emission methods for monitoring
the condition of the construction. Complete usefulness of the AE method applied in monitoring
the destructive processes in structures was confirmed, especially that it allows to assess
the occurring destructive processes in the conditions of real exploitative loads. It was shown
that the presented method is a successful diagnostic tool enabling effective and safe
functioning of intelligent city.
