This paper discussed the mechanism of stress transfer and the strength of beam-to-column connections with/without stiffening plates. The conclusions attained are as followings. (a) From the results of the model tensile tests of the connections without stiffening plates, i) The strength of the connections depends on the width and thickness of column flange, the thickness of column web and beam flange, and the steel grade of the materials used. ii) The yield and maximum strength of the connections can be evaluated by Eq.(4), which was proposed by Zoetemeiier P., and Eq.(6) respectively. (b) From the results of the model tensile tests of the connections with stiffening plates, i) Four fracture modes are observed, i. e., Mode W, WS, S and E (see, Fig. 9). ii) The maximum strength of the connections of Mode W or WS can be evaluated by Eq.(10) or Eq.(12) according to the ultimate strength of the welding seam between stiffening plates and column flange. iii) Eq.(14) is obtained experimentally for the maximum strength of the connections of Mode E. (c) From the results of the sub'assemblage tests, the evaluating equations of the maximum strength of the connections obtained by the model tensile tests are applicable to the connections of the sub-assemblage conservatively.
