【 摘 要 】

In the process of industrial buildings and structures designing, which constructions are also perceived by dynamic loads in addition to static loads (for example, with technological equipment), as well as in the calculation of civil buildings' structures, taking into account the pulsating component of the wind load, it is necessary to perform frequency analysis as a part of a more general dynamic analysis. The essence of frequency analysis is in the fact that it can be used in various frequency characteristics of dynamic loads. In order to avoid resonance which leads to the destruction of structures, the frequency range of dynamic load must not coincide within the range of natural oscillations frequencies of structures. The conducted researches allow us to speak about influence of pliable connections on frequency characteristics. Therefore, an urgent topic is the study of support constraints' compliance effect on natural oscillations frequencies of building constructions.
