The full plastic and ultimate strength of connection were analyzed by assuming yield and ultimate mechanism respectively. The yield mechanism assumed can be classified as follows, yield mechanisms by moment yield lines in H flange(Y HF) and split-T flange(Y-TF), yield mechanism by the combination of moment yield line in split-T flange and bolt yielding(Y-TB), and yield mechanism by bolt yielding(Y-BB). The ultimate mechanism assumed can also be classified as follows, ultimate mechanisms by maximum moment lines in H flange(U-HB(a) and (b)) and split-T flange(U-TB) in connection with local ultimate state of connected bolts respectively, and ultimate mechanism by tensile strength of bolts(U-BB). The related experimental strengths of connections were analyzed by the presented strength equations showing appropriate coincidence, and the applicability of each yield and ultimate mechanism to the connection details is studied by numerical analysis of model connections.
