EFFICIENT STEEL FRAME STRUCTURE OF MULTI-STOREY BUILDING

Currently, many buildings in Ukraine are affected by significant dynamic loads associated with military operations on the territory of the country. In practice, this can lead to the so-called progressive destruction, however, unlike static loads, shock-explosive loads require an assessment of not only the mechanical characteristics of the building, but also an assessment of its own dynamic characteristics. Such characteristics traditionally include the spectrum of natural frequencies and the forms of oscillations corresponding to them.
