中文摘要：

为了研究配筋砌块砌体剪力墙的抗震性能,在6个配筋砌块砌体剪力墙物理试验的基础上,研究并提出了一种考虑弹塑性剪切变形的纤维模型.通过按照试验条件所进行的滞回性能数值模拟与物理试验结果的对比,表明应用所改进的纤维模型模拟计算能较好地反应配筋砌块砌体剪力墙滞回性能.分析也表明,在一定条件下普通的纤维模型对于配筋砌块砌体剪力墙滞回性能分析仍是适用的,但应用本文所研究的纤维单元计算结果更好.在此基础上,利用均匀设计法安排数值试验,回归给出了一字型配筋砌块短肢砌体剪力墙滞回性能特征参数的经验公式,建议了此类配筋砌块砌体剪力墙结构弹塑性地震反应分析的滞回规律模型.

英文摘要：

In order to research the seismic performance of reinforced concrete block shear walls（RCBSW）,this paper has developed a new fiber element model that considers the elastic-plastic shear deformation.The comparison between experimental results and simulation results of 6 RCBSW organized under the same conditions shows that this new fiber element can preferably simulate the hysteretic performance of RCBSW.Although the ordinary fiber element model is still suitable to simulate the hysteretic performance of RCBSW conditionally,it brings on better results for this new fiber element.Based on the above research,after some numerical simulation on uniform design experimentation method,a series of empirical formulas of characteristic parameter of a kind of RCBSW is induced and the hysteretic model for elastic-plastic seismic response analysis of this kind of RCBSW is proposed.
