Abstract

In this paper, fill-scale tests of composite beam subassemblages are performed and the following conclusions are derived.1)The accumulated plastic deformation capacities, η(Σbθp1)and ηs+(bθs+) of composite beam are reduced to maximum 50 and 30 % of steel beams, respectively.2) n of non-scallop type is 1.5 times as much as conventional scallop type.3) Incremental strain of skeleton stress-strain curve in the bottom flange of the composite beam is 2.0 times as much as steel beam when the position of neutral axis is in the upper flange.4) Strain at fracture of the flange of composite beam specimen corresponds to the calculated one according to APD fracture evaluation flow.
