指出了钢筋混凝土桥墩数值模拟中考虑地震反应与能力相互作用的必要性，初步建立了其设计流程，提出了有限元程序的实现流程。基于Opensees2．0．0版本源代码二次开发了一个新的塑性铰单元，数值结果表明，方法能够实现桥墩骨架曲线的负刚度段，从而避免一般有限元计算中负刚度段不收敛的困难；与试验结果的比较可以发现，方法能够较好地模拟桥墩在不同加载模式下的试验现象。这说明方法能够实时地反映构件的状态，并根据反应对其能力进行修正，从而考虑反应与能力的相互作用。

The necessity of considering the interaction between seismic response and ability of RC bridge piers was pointed out.The design procedure was basically established.The realization procedure of the finite element program for design was proposed.A new plastic-hinge element was developed based on the source code of Opensees 2.0.0.The numerical results showed that the proposed method can be used to realize the pier skeleton curve with negative stiffness,so as to avoid the non-convergence difficulty caused by the negative stiffness curve in common finite element computations. According to the comparison between experimental and numerical results,it was shown that the proposed method here can be used to simulate experimental phenomena under different loading patterns;the method can be used to on-time reflect the members' state,and modify their ability according to their response,so the interaction between response and ability is considered.
