Two tests of semi-rigid steel sub-assamlages were conducted to investigate cyclic behavior of those. The frames consist of RHS columns and wide flange beams. One of them has a connection stiffened by external diaphragms, and the other one has a connection stiffened by an internal diaphragm positioned at height of flanges of a deeper beam, suppressing the stiffener at height of a bottom flange of a shallow beam. Local deformation occurred in the connections for both of the frames. Test results showed that the frames have sufficient rotation capacity in spite that the frames have flexible and/or weak beam-to-column connections. Results of simple calculation were shown to trace behavior of one of frames that has an externally stiffened connection. Prediction of yield strength of the other frame stiffened by internal diaphragms, by using yield line theory agreed well with actual strength.
