Experimental results of 14 speciments including concrete-filled rectangular tubular (CFRT) short columns, steel tubular short columns and plain concrete short columns are presented. Based on the test results, the failure mechanism, ductility and ultimate capacity of CFRT short columns are investigated. The effects of the main factors such as D/t ratio and concrete strength on the behavior of concrete-filled square steel tubular short columns are discussed as well.
Keywords: concrete-filled rectangular steel tube; capacity; ductility
