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 research status of the impact resistance of CFST and RACFST was introduced. The impact of CFST under different factors such as strain rate, high temperature, restraint coefficient, material strength, impact energy and outsourcing constraint was summarized. Performance of the relevant research results, cite the current lack of research for steel pipe recycled concrete. According to the impact resistance of concrete filled steel tube and the related properties of recycled aggregate concrete, the impact resistance of recycled concrete with steel tube is deduced. The results show that the recycled aggregate concrete of steel pipe has good impact resistance, and the relevant conclusions provide reference for the further study on the impact resistance of recycled aggregate concrete.
