Abstract:
EN: Last years the problem of safety in buildings has been paid a lot of attention. Very often explosions, fires, earthquakes, sudden destructions of supports cause theaccident and lead to progressive collapse. Thus, the calculation of the stability to progressive collapse of building structures is very acute question today. It should pay particular attention to the considerations of dynamic effect during destruction and it should take into account dynamic increase factor. The analysis and review of the standards and the scientific literature on this problem indicates that we have not a clear understanding of the value of dynamic increase factor of different failure types.
Purpose of the study. To review the standards and the scientific literature on emergency
load calculations that are linked with stability to progressive collapse of building structures and dynamic influence of localized structural component damage (failure) on the building structure. To study the dynamic influence on the building structure of its localized structural component damage by laboratory experiment and numerical simulation.
