Considering the construction peculiarties of precast segmental bridge columns, the special problems with regard to the joints, the bonded prestressing tendons, the unbonded prestressing tendons and the energy-dissipating device, were studied. On this basis, the fitted analysing method, the fiber beam-column element method, was provided, with which the specimens were analyzed under cyclic loading and nonlinear dynamic time history loading. Comparing with the experimental results, the method proposed is reasonable and effective for precast segmental bridge columns.
