摘要:
研究了后张预应力预制桥墩的抗震解析计算方法,以2种不同连接方式的预制桥墩拟静力试验为背景,基于关键截面轴力和弯矩平衡及桥墩墩底整体弯矩平衡,推导出了预制桥墩水平力-相对位移关系计算过程,研究了耗能钢筋配筋率、高宽比对预制桥墩抗震性能的影响。结果表明:解析计算结果和纤维模型计算结果与拟静力试验结果基本一致,解析计算方法可以代替纤维模型方法进行预制桥墩抗震性能计算。
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.
