In the design of wide-flange column-to-wide-flange beam rigid connections, the weak-axis beam-flanges are sometimes welded between the column-flanges and used as transverse stiffeners for the strong-axis beams. Although the transverse stiffeners are generally designed in consideration of only the strong-axis beam-flange force, transverse stiffener strengths are possibly influenced by the weak-axis beam-flange force. A recent study by the authors investigated the strength formulae of the strong-axis beam-flange-to-column connections with transverse stiffeners. In the present paper, the strength formulae considering biaxial yield criterion of normal and shear stresses are derived and compared with the previous strength formulae by the authors. Some elastic-plastic finite element analyses are performed for connection models in order to examine the accuracy of derived strength formulae. The analysis results demonstrate the influence of the column type on the connection strength and the strength reduction under weak-axis beam-flange force.
