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.

Guangzhou Xita Project uses a special exterior frame which consists of huge inclining concrete-filled columns. To ensure the engineering quality and select the suitable concrete-filled steel tube column structure, two concrete-filled steel tube column structure experiments have been carried out. To ensure the quality of the concrete-filled steel tube column structure experiment, the C100, C90 and C70 high performance concrete experimental research have been done specially, and the result of the experimental researches has been used in concrete-filled steel tube column structure sample successfully. The raw materials, mixture proportions and performance of the high performance concrete were discussed in this paper.

Axial Load Ratio

This article experimentally investigates the cyclic behavior of ultra high performance concrete–filled steel tube beam-columns. A total of eight specimens were tested. The considered parameters were the axial load ratio and steel ratio. The results showed that all ultra high performance concrete–filled steel tube beam-columns had a very good cyclic behavior without significant pinching. Increasing the axial load ratio results in the decrease of strength and ductility, but it has no obvious influence on the initial flexural stiffness. Reducing the steel ratio results in the decrease of the strength, stiffness and ductility, and energy dissipation capacity.
