摘　　要：介绍了钢管混凝土(CFST)和钢管再生骨料混凝土(RACFST)抗冲击性能的研究概况,总结了钢管混凝土在应变率、高温、约束系数、材料强度、冲击能量和外包约束等不同因素影响下冲击性能的相关研究成果,列举出目前对于钢管再生混凝土研究的不足之处。根据钢管混凝土抗冲击性能以及再生骨料混凝土相关特性,推测了钢管再生骨料混凝土的抗冲击性能。结果表明:钢管再生骨料混凝土具有良好抗冲击性能,相关结论为钢管再生骨料混凝土抗冲击性能的进一步研究提供了参考。The general research situations of the impacts of concrete-filled steel tube （CFST） and recycled aggregate concrete-filled steel tube （RACFST） were introduced. The relevant research results of the impact property of CFST under different factors, such as strain rate, high temperature, constraint coefficient, material strength, impact energy and outsourcing constraints, were summarized. The current research results were summarized and the shortage of the current research were listed. According to the impact of CFST and the related properties of recycled aggregate concrete, the impact resistance of recycled aggregate concrete were speculated. The results show that RACFST has good impact resistance. The relevant conclusions indicate the direction of the further research on the impact property of RACFST.
