This paper describes the mechanical behaviour of the high strength bolted H-beam to H-column connections with T-stub (split-tee) under alternating repeated load. The loading tests were conducted by using the full scale specimens of the beam-to-column connections. The objects of the study were to examine the strength and deformation capacity of split-tee type connections reinforced differently, and to compare the split-tee type connection with the usual welded type connection. The main results are as follows: 1. The hysteretic characteristics of the split-tee type connections are similar to those of the usual welded type connection, and the hysteresis loops of the split-tee type connections are stable and indicative of their large energy absorbing capacity. 2. Doubler plate reinforcement effectively decreases shear stresses in panel zones and restricts shearing deformation.
