To quantify the post-earthquake residual seismic capacity of reinforced concrete (RC) column members, experimental data for 6 column specimens with flexural, flexural–shear and shear failure modes are used to derive residual seismic capacity of damaged RC column members for specified damage states in this work. Besides of the experiment data, some related researches are also investigated to suggest the reduction factors of strength, stiffness and energy dissipation capacity for damaged RC column members, respectively. According to the damage states of RC columns, their corresponding seismic reduction factors are suggested herein. Taking an RC column with the flexural–shear failure for an example, its reductions factors of strength, stiffness and energy dissipation capacity are 0.5, 0.6 and 0.1, respectively. This work also proposes the seismic performance assessment method for the residual seismic performance of earthquake-damaged RC buildings. In the case study, this work selects one actual earthquake-damaged school building to demonstrate the post-earthquake assessment of seismic performance for a damaged RC building.

钢筋混凝土柱受损构件残余抗震能力的实验量化

为了量化钢筋混凝土（RC）柱构件的震后残余抗震能力，使用具有弯曲，挠曲-剪切和剪切破坏模式的6个柱试样的实验数据，得出指定破坏状态下受损RC柱构件的残余抗震能力。在这项工作中。除了实验数据外，还对一些相关研究进行了研究，以分别提出受损RC柱构件的强度，刚度和能量消散能力的降低因子。根据RC柱的破坏状态，提出了相应的减震系数。以带有弯曲剪切破坏的RC柱为例，其强度，刚度和能量耗散能力的折减系数分别为0.5、0.6和0.1。这项工作还提出了针对地震破坏的钢筋混凝土建筑物的剩余抗震性能的抗震性能评估方法。在案例研究中，这项工作选择了一栋实际的地震破坏的教学楼，以证明震后对一栋受损的RC建筑的地震性能的评估。
