摘　　要：以再生块体强度、再生块体粒径、自密实混凝土强度、轴向力偏心距、钢管壁厚为参数,设计制作了12根试件,通过对其进行了偏心受压承载力试验,以研究钢管-RBSCC短柱偏心受压性能.研究表明:再生块体强度、自密实混凝土强度、含钢率对偏心受压承载力产生正相关影响;偏心距对偏心受压承载力产生负相关的影响,且影响程度最大;再生块体粒径对偏压承载力产生正相关的影响,但影响程度较小,实际计算时,可以忽略;针对该类结构可采用本文建议的钢管-RBSCC短柱偏心受压承载力计算方法进行计算,为废弃混凝土的工程应用提供了一种途径.Taking the RB strength,RB particle size,SCC strength,eccentricity of axial force and wall thickness of steel pipe as parameters,12 specimens are designed and manufactured in this paper.Through the eccentric compression bearing capacity test,the eccentric compression performance of steel tube RBSCC short column is studied.The results show that the RB strength,the SCC strength and the steel content have a positive correlation effect on the eccentric compression bearing capacity;Eccentricity has a negative correlation effect on the bearing capacity of eccentric compression,and the influence degree is the largest;The RB particle size has a positive correlation effect on the eccentric bearing capacity,but the influence degree is small,which can be ignored in the actual calculation;For this kind of structure,the calculation method of eccentric compression bearing capacity of steel tube RBSCC short column proposed in this paper can be used to calculate,which provides a way for the engineering application of waste concrete.
