Abstract:: 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.
