Abstract:

:In order to investigate the shear behaviors of the high-strength bolts penetrating through the concretefilled thin-wall square steel tube column with ribs in non-slip critical connections, four specimens were tested, finding that the adopted connection is capable of transferring the shear force loading on the bolt reliably. The experimental results were then analyzed and a calculation model for the penetrated high-strength bolt was established. Moreover, a formula to calculate the shear resistance of the bolt was put forward by considering the possible failure modes, which was finally used to calculate the shear resistance of the bolt. The calculated results accord well with the experimental ones.

Key words: concrete-filled square steel tube column, rib, high-strength bolt, shear behavior
