Abstract:
Under the background of pseudo static test of precast bridge piers with two kinds of connection manners, the seismic resistant analytical calculation method of posttensioned precast bridge piers was investigated. The calculation process of lateral force-displacement relation was deduced based on critical sectional axial load and bending moment equilibrium and entire bending moment balance at column base. The influences of reinforcement ratio of energy dissipation bars and height-width ratio on the seismic resistant behaviors of precast bridge piers were discussed. The results indicate that the analytical calculation results and fibre model results are in accordance with pseudo static test results, the analytical calculation method can substitute for fibre model in the calculation of precast bridge pier seismic resistant behavior.
