The effectiveness of improved connection details on the deformation capacity of composite beams has been investigated. Two types of improved connection details have been introduced to the composite beam specimens : a no weld access hole detail and a RBS(Reduced Beam Section) detail. Cyclic and quasi-static loading tests have been performed using full-scale specimens including the specimens with improved connection details and with conventional connection detail. The specimens with improved connection details have shown large deformation capacities than the specimens with the conventional connection detail. The no weld access hole detail has improved the moment capacity of the beam near the beam-to-column connection. Because of this effect, a wide area of the beam has yielded, so that the large deformation concentration and the flange fracture have not occurred. The RBS detail has also prevented the deformation concentration to the connection and the flange fracture by developing large plastic deformation area.
