[摘要]分別基于三維實(shí)體單元模型、纖維單元模型、彎剪分析模型和構(gòu)件恢復(fù)力模型,對(duì)2個(gè)鋼筋混凝土剪力墻試件進(jìn)行了滯回性能的模擬分析??紤]了試件的彎曲與剪切破壞形態(tài),并將各模型模擬得到的剪力墻滯回曲線與試驗(yàn)結(jié)果進(jìn)行了對(duì)比。結(jié)果表明,三維實(shí)體單元模型模擬得到的滯回曲線在達(dá)到極限荷載前與試驗(yàn)結(jié)果吻合良好;纖維單元模型可有效模擬彎曲破壞的剪力墻試件,但對(duì)剪切破壞的剪力墻試件模擬效果較差;彎剪分析模型和構(gòu)件恢復(fù)力模型可較好地模擬分析彎曲或剪切破壞剪力墻試件的滯回性能。研究可為鋼筋混凝土剪力墻結(jié)構(gòu)的抗震分析和設(shè)計(jì)提供參考。

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
