摘要：The article presents a comparison of results of experimental and analytical calculations of the strength of the central and eccentrically compressed concrete elements working in the conditions of dynamic loads under fire exposure. The diagram shows a coefficient of dynamic strength depending on the dynamic loading under high temperature obtained by experimentation way. It is shown, that accounting the dynamic effects in fire condition reduces the load carrying capacity of columns by 40%. Therefore, it is recommended to check the possibility of progressive collapse of buildings and, results of which, appearing the character of dynamic loads on the structure, in calculating load carrying capacity of the structure in fire testing.
