本文建立了钢筋混凝土墙平面外屈曲的有限元模型。混凝土采用非线性正交各向异性16 d.f.板弯曲单元;钢筋采用弹塑性梁单元。在结构的平面应力计算使用四个或八个节点的膜元素与杆元素用于钢筋。通过确定面外切线刚度的行列式何时变为零来计算屈曲载荷。有限元模型与现有的实验结果的比较表明，良好的协议。
In this paper a FE model for the study of the out-of-plane buckling of reinforced concrete walls is derived. The concrete is modelled using non-linear orthotropic 16 d.f. plate bending elements; the reinforcing steel using elasto-plastic beam elements. In the plane of the structure stresses are calculated using either four or eight-node membrane elements with bar elements used for the reinforcing steel. The buckling load is calculated by determining when the determinant of the out-of-plane tangent stiffness becomes zero. Comparison of the FE model with available experimental results shows good agreement.
