A moment resisting connection has been proposed for a frame consisting of circular concretell~ d steel tube columns and composite steel and concrete beams. A series oftests at the University ofMelboume ?IHtoredthe behaviour ofa 'It.stub element ofthe proposed connection, under cyclic tension. The T-stub element orisisted of a rigid curved endplate welded to a tapered plate which formed the web ofthe 1. The curved endplate y#s then bolted to a concrete-filled CHS column, using Ajax blind bolts. Four of the test specimens had Grade 90 reinforcing bars of various configurations (long, short, straight, cogged) welded to the head of the blind olts to anchor the bolts into the concrete inside the CHS. This paper reports the results of these tests.
