Abstract:
To obtain the bond strength calculating formula of concrete-filled square steel tube specimens, push-out experiments were carried outunder different slendernesses and width-thickness ratios, and the change principle of bond strength of concrete-filled square steel tube specimens was obtained. According to domestic and foreign experiments, authors proposed that when the thin-walled concrete damaged, the sample was destoryed. Base on this principle, a semiemprical theory formula was deduced using elastic mechanics and material mechanics methods. Analytical results show that bond strength of concrete-filled square steel tube specimen is more affected by width-thickness ratio, and is less affected by the slenderness. The results of formula match well with those of experiments, which provide a new way to calculate bond strength of concrete-filled square steel tube columns.
