Abstract

The confining effect of concrete was studied when a steel tube is set at the inside face of a hollow reinforced concrete column. To investigate the confining effect by a steel tube, 36 specimens were tested and compared. Test results show that the inserted steel tube provide sufficient confinement to the confining effect depends on the thickness of the steel tube. And also, test results show that the provided confinement by a steel tube increase the strength of concrete.
