ABSTRACT
Tests have been carried out on eight full-scale composite connections in which the columns were manufactured of concrete-filled steel rectangular hollow sections (RHS). The symmetrical connections were assembled by bolting the webs of two steel beams to the columns through the use of Tee cleats welded to the side walls of the steel hollow section. In each test, loads were applied to both column and beams in order to simulate actual column loading in buildings. The beams were loaded symmetrically, and both column and beams were loaded in order to represent a column length in a multi-storey structure. Four different eccentricities of the beam loads from the column face were used in these tests, and the beam and column loads were increased proportionately. The columns were about 3m long, and thus represented a floor height in typical multi-storey buildings.
