Thanks to intensive research in the field of polymer adhesives in the last few years, there is a possibility of using a glued joint with a real load bearing role. The reliability of adhesive in the connection during the lifetime of a structure is affected by many factors, but the initial choice of a proper adhesive material is the most crucial one. The article deals with the experimental analysis focused on the determination of material characteristics of adhesives in planar connections, it describes the effect of various factors on the behavior of an adhesive joint under increasing loads, its ultimate bearing capacity and its failure modes. The main investigated factors are the type of adhesive, the type of connected materials (material of substrate), surface treatment and the thickness of the adhesive layer. A special part of the article describes numerical models of a glued joint with respect to different types of adhesive.

Today, at the beginning of the 21st century, the standards of living conditions are defined by the current financial and economic situation. It has impacts on the smallest details of everyday life as well as on residential purchases and constructions also. These are the sectors that mainly felt the lack of funding in the recent years. Although the treatment of this problem should be a simple answer, ecological, economical and social factors generate a more difficult solution. A very important issue in today’s society concerns making the use of the un-preferred living spaces within an existing home. There are many types of these living spaces, including for example out-of-date country buildings that have lost their function, or a variety of apartments in the cities. It became clear that living in prefabricated (panel) buildings is the most undesirable for the population, so the biggest part of the research is about the theoretical rehabilitation of these buildings.

The society is changing faster and faster. The technical development times are constantly growing shorter, whereas the rate of development is increasing exponentially. Hence, the treatment of the environment is also changing. The society responds to these changes by becoming more and more flexible and adapts itself to new situations.

In contrast to this, the construction is static and the construction industry is conservative. The further development of construction methods and materials is also slow. For centuries, the same materials have been used.

The requirements to living space become more and more multiple. Dwellings are usually made for one use, one setting of requirements. The result is a growing vacancy of dwellings. The shown project, which is under realization at the moment is coming up with one possible solution for a dwelling to use it with multiple requirements.
