Abstract: Tests on 135 battened composite specimens are performed to investigate the bond between concrete and steel in battened composite columns. Several factors believed to affect the bond between the two materials are investigated, ...

Abstract: Tests on steel hollow tubes of square and circular sections filled with foamed and lightweight aggregate concrete were conducted to investigate the contribution of these concretes to the strength of cross sections of ...

Abstract: An experimental study was conducted to investigate the composite action of foamed and lightweight aggregate concrete. Thirty-six push-out tests were performed on concrete-filled steel hollow sections of square and circular ...

Abstract: Experimental results of previous research showed that the bond strength between structural steel shapes and concrete in composite sections at the age of one year is approximately 30% of that at the age of three weeks. A ...
