[提要]  建立鋼筋混凝土雙肢剪力墻彈塑性分析的有限元模型，采用有旋轉(zhuǎn)自由度的高精度平面單元分析墻體在周期荷載作用下混凝土開裂、屈服和鋼筋屈服的變化過程，為鋼筋混凝土雙肢剪力墻的抗震設(shè)計(jì)提供較精確的分析方法。
[關(guān)鍵詞]  雙肢剪力墻 鋼筋混凝土 彈塑性 周期荷載 旋轉(zhuǎn)自由度

Using the high precision plane elements with ratational degree of freedom, a finite element model for reinforced concrete coupled walls is founded to analyse the process of crack and yield under cycle load. Also, a more accurate method of anti-seismic design for reinforced concrete coupled walls is presented.
Keywords: coupled wall; reinforced concrete; elasto-plastic; cycle load; rotational degree of freedom
