In this study, Flexural tests for prefabricated composite columns using steel angle and band steel were carried out. The composite columns are fabricated by bolting the angles and the band steels before casting concrete and named, therefore, B-PSRC(Bolt-connected Prefabricated Steel Reinforced Concrete) columns. A SRC composite column and four of B-PSRC columns were prepared for flexural load tests. From the test results, all the specimens showed flexural failure, which is due to rupture of hole-section at the angle-bolt joints. Shear failure caused by bond slip between the angles and concrete was not found in any of specimens. The flexural strength of B-PSRC columns which were designed, the same steel ratio as the SRC columns was shown to be higher than that of SRC columns.
