Attempts on the modeling for elastic-plastic behavior of beam to column connections subjected to unsymrhetrical beam moment have been presented in References. However, the writer know that the models presented in the References would not always agree with experimental results. Therefore, the writer examined in detail resistance force of beam to column connections composed of wide flanges, and attempted to model its resistance force. It was assumed that the shearing resistance of the panel zone is an average shearing stress and the resistance of the elements surrounding the panel zone is the bending moment at the four corner points. Based on the consideration of the lower and upper bound on the strength of the connection, the comparison with the test results was carried out. The results of this comparison are discussed and summarized in this paper, and it has been concluded that the modeling for resistance, of the panel zone and the frame action surrounding the panel zone introduced in this paper is useful to explain the elastic-plastic behavior of beam to column connections composed of wide flanges.
