Abstract
Through-gusset HTB-connections of single shear type are often used for axially compressed tubes. In this case, the eccentricity with the amount of gusset-thickness may cause the reduction of buckling strength as compared with the double shear type. This paper deals with the estimation of buckling strength and mode for such eccentric systems. Analytical results show that the buckling strength of the eccentric system can be significantly reduced when the stiffness and the strength of the gusset-plate are comparatively small. The accuracy of the analytical estimation is confirmed by comparing to the results of buckling tests.
