【 摘 要 】
The purpose hereof is to study the specifics of the force resistance and to experimentally identify the reinforcement effect of short square-section concrete-filled steel tube elements (CFSTE) with spiral reinforcement. Analysis of the laboratory samples of concrete-filled steel tube columns shows that spiral reinforcement makes them stronger by 18÷43% depending on the source concrete class. Maximum recorded longitudinal deformation in spiral-reinforced samples is 1.7÷2 times larger. Using a relatively small amount of spiral reinforcement (about 1%) has resulted in a mean 23% stronger reinforcement effect in the studied structures. Such structures remain efficient when using high-strength concrete.
