The effect of construction type, the existing of additional energy-dissipating device, and the bond condition are selected as the experimental variables. From the experiment, the strength, energy dissipation capacity, residual displacement, general hysteretic behavior and mechanical behavior were obtained. The segmental columns experience opening-closing between the segmental interface under cyclic loading, has no plastic hinge mechanism at the bottom of the column commonly seen in conventional columns. Thus, the similar functionality while less damage to the system is achieved. The residual displacement of segmental bridge column with bonded or unbonded prestressing tendons is less The addition of energy dissipation bars crossing the joint could delay the gap opening, increase the strength and the hysteretic energy dissipation of the column.
