Highlights Evaluates the bond behavior of MS-CFT columns. Conducts 54 push-out tests on MS-CFT columns. Evaluates the effects of four governing parameters. Proposes bond stress-slip relationships for MS-CFT columns.
Abstract This paper experimentally investigates the bond strength and behavior of concrete-filled steel tube columns using manufactured sand (MS-CFT). A total of 54 push-out tests on MS-CFT columns are conducted. The test parameters are: (i) type of stone that was used to manufacture the sand (i.e., limestone or pebble), (ii) steel tube diameter-to-thickness ratio, (iii) concrete compressive strength, and (iv) stone powder content. Results from the tests indicate that: (i) MS-CFT columns have higher bond strength than CFT columns, (ii) the bond strength of MS-CFT columns increases with decreasing steel tube diameter-to-thickness ratios; (iii) MS-CFT columns using limestone to manufacture the sand have slightly higher bond strength than those using pebble to manufacture the sand; (iv) the influence of the concrete compressive strength on the bond strength of MS-CFT columns is not consistent; and (v) the bond strength of MS-CFT columns is slightly influenced by the stone powder content. Idealized bond stress-slip relationships for MS-CFT columns are also proposed. The proposed relationships reasonably matched the experimental bond stress-slip response of the 54 MS-CFT columns.
