摘要]分别基于三维实体单元模型、纤维单元模型、弯剪分析模型和构件恢复力模型,对2个钢筋混凝土剪力墙试件进行了滞回性能的模拟分析。考虑了试件的弯曲与剪切破坏形态,并将各模型模拟得到的剪力墙滞回曲线与试验结果进行了对比。结果表明,三维实体单元模型模拟得到的滞回曲线在达到极限荷载前与试验结果吻合良好;纤维单元模型可有效模拟弯曲破坏的剪力墙试件,但对剪切破坏的剪力墙试件模拟效果较差;弯剪分析模型和构件恢复力模型可较好地模拟分析弯曲或剪切破坏剪力墙试件的滞回性能。研究可为钢筋混凝土剪力墙结构的抗震分析和设计提供参考。

Abstract: Hysteretic analysis was conducted for two reinforced concrete shear wall specimens based on three-dimensional solid element model, fiber element model, bending-shear analysis model and restoring force model respectively. Considering the failure modes of bending and shear, the simulated hysteretic curves from above models were compared with experimental results. The results show that the simulated hysteretic curves by three-dimensional solid element model agree well with experimental results until the ultimate load stage. The fiber element model predicts the hysteretic curves of the specimens with bending failure well, but not effective for the specimens with shear failure mode. The bending-shear analysis model and restoring force model can simulate and analyze the hysteretic curves of the specimens with bending or shear failure modes. This study provides a reference for the seismic analysis and design of reinforced concrete shear wall structure.

Keywords: reinforced concrete shear wall; hysteretic behavior; simulation analysis; bendingshear analysis model; restoring force model
