In this study, section detail of a prefabricated composite column applying hing-strength angle was developed. 2/3 scale eight specimens of the composite beam were tested under two-point loading to evaluate the flexural performance
of the sections and the bond performance of the angle. The test parameters were the steel arrangement, the steel ratio, and the space of rectangular hoops. The sizes of the composite beams were 400mm×400mm and 500mm×500mm, and a
beam length was 4500mm. For self-supporting during construction, special details using welded ties to angle were used to make up the column cage. The test results showed that the composite beam applying angle exhibited better flexural
strength than those of H-type steel. Under 200mm spacing of hoops, bond-slip of the angle was prevented before flexural capacity.
