Abstract

Design formula has been proposed for local tensile yield strength of unstiffened type connection between concrete filled circular steel tubular column and beam flange. The local connection interface region has been classified to two regions; around the middle region of the flange, and the rest flange edge region. The steel in this edge region has been assumed to be yield fully under the Von Mises' yield condition, In the partially yield middle region, its stress block factor has been assumed to be a function of the full yield strength of the tubular steel relative to the flange's one.
