摘要
本文总结了现行位移延性能力计算方法,对不同参数桥梁高墩计算模型采用Pushover法进行分析并与公式法比较,讨论了两种方法在计算桥梁高墩位移延性能力时的适用性,并指出位移延性能力计算偏差对抗震设计有较大的影响。
In this paper, the applicable calculational methods of displacement ductility capacity are summarized, and varied parametric models of tall pier are analyzed with Pushover analysis method and formula method. The applicability of two methods is discussed in calculation of displacement ductility capacity, and the influence of its error on seismic design is pointed out.
