The cross section arrangement of shape steel in transfer columns of SRC-RC hybrid structure was analyzed based on low cyclic reversed loading test of 16 specimens. The results showed that area ratio of shape steel has serious effect on seismic behavior of transfer columns. Displacement ductility decreases along with the increment of shape steel arrangement, but carry capacity increases at the same time. Partially existed shape steel makes the aberrance of internal stress and hence leads serious shear effect to transfer columns, so deformation ability and postpeak behavior degenerate when area ratio of shape steel promotes. Shape steel not only makes the flexural stiffness of cross section advanced but also postpones the appearance of cracks, and hence increases elastic lateral stiffness of specimens, but lateral stiffness at yielding point has little effect by shape steel arrangement. Through test and theoretical calculation, maximum of bending capacity in rational range of shape steel arrangement was confirmed which can be used to prohibit serious shear effect and insure deformation ability against brittle failure. Test data and the analysis results could provide references to seismic design and construction of hybrid structure.
