    Abstract:

    The main objective of this paper is to examine the feasibility of the hybrid bridge column. To address this problem, quasi-static tests are conducted to explore the differences of seismic behaviors between hybrid bridge column and reinforced concrete(RC)bridge column and STRC bridge column, each column with shear span ratio of 3. 0. The test results show that flexural-ductile failures are observed for all three columns, and much more cracks with wider distribution area are found to be created in the hybrid bridge column. This demonstrates that the hybrid bridge column yields a much better seismic behavior over the RC bridge column. In addition, the ductility and self-centering capability of hybrid bridge column are superior to those of the STRC bridge column. In general, the hybrid bridge column has the advantage of both economical efficiency and favorable seismic behavior, thus can be considered as a highly competitive bridge column scheme in seismic active regions.
