| 摘 要： | 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 COLUMN SUPPORTED SHEAR-WALL STRUCTURES USING COMBINATION METHOD OF PLAN ELEMENT WITH BAR ELEMENT |
| |
| Abstract: | Abstract The shear wall structure supported by column calculated by plane dement leads to increase moredegrees of reedom.A method using the combination of two dimensional rectangular finite elements withone-dimensional bar finite elements for calculation of shear-wall structures supported by columns is presented. The compatibility at the nodes between walls and columns is represented by Lagrangian Multiplier,the total stiffiness equation of shear-wall structure is determined by the method of minimizing potential energy function |
