摘要：
The article introduces the results of the experimental research of the effect of confinement and steel fiber reinforcement on the strength and strain of the compressed elements of high-modified as well as high-strength SFRC. Analytical expressions to describe the strength and strain of elements with confinement reinforcement under axial compression have been proposed. The results of the research of the effect of concrete age and temperatures elevated up to 150 degrees C on the strength and strain of high-strength SFRC have been introduced. (C) 2015 The Authors.
