采用二维平面元计算框支剪力墙导致节点自由度个数过多，作者根据框支剪力墙板、柱混合体系的特点分别采用二维矩形元和一维杆系元，并引进拉格朗日乘子来反映框支剪力墙板、柱节点的约束条件，用势能最小化方法建立起框支的力墙结构的刚度方程。计算实例表明，该方法不仅有足够的精度，而且也可减少计算机的运行时间。
The calculation of frame-supported shear walls using two-dimensional planar elements leads to an excessive number of degrees of freedom of the joints. The author uses two-dimensional rectangular elements and one-dimensional rod elements respectively according to the characteristics of frame-supported shear wall plates and column mixing systems, and introduces the pull. The Langmuir multiplier reflects the constraints of shear wall panels and column joints of frame supports, and uses the potential energy minimization method to establish the stiffness equation of the wall structure of frame supports. Calculation examples show that this method not only has sufficient accuracy, but also can reduce the computer’s running time.
