It is well known that the resistance of the connection increases further even after yielding of the panel plate. This additional panel moment is caused by strain hardening of the panel plate and the reinforcement of the elements surrounding the panel. This paper presents an experimental and analytical approach to the evaluation of the contribution of these elements to this additional strength. First, bending tests of a flange with a short span, and then of the intersection point of the beam and column flanges were carried out. On the basis of these experimental and numerical results it was found that a scallop and a backing plate also have a large contribution to the additional strength of the connection. Lastly an evaluating method of the maximum bending strength of the beam and column flange intersections considering these factors is presented.
