This work is dedicated to an experimental research of strength and resistance characteristics of axially loaded concrete filled steel tube elements of self-stressing concrete, including high-performance concrete. Labcrete specimens of circular section 112 mm in diameter and 1000 mm in length were used in experiments. The research shows that the use of self-stressing concrete increased the strength of the specimens by approximately 10%, and enhanced elastic behavior limit by 20-33%. In the course of testing self-stressing concrete specimens, registered longitudinal deformations were within 0.52-0.75%. Analysis of the obtained results indicates a significantly greater case effect in the pre-stressed specimens. This effect is somewhat less pronounced in high-performance concrete specimens, yet still prominent. |
