【摘要】 应用能量方法，通过对两个垂直方向取不同的位移函数，推导出了具有１２个自由度的四结点矩形单元的单元刚度矩阵．算例表明这种带有倾向性的单元（ＴＲＥ）的精度远高于普通四结点矩形单元，在某些场合其精度甚至高于高精度单元．更多还原

【Abstract】 By using energy method principle and different displacement function in two vertical directinns, the element rigid matrix of a 4-name rectangular element with 12-freedom is derived in this poper. The examples demonstrate that the accuracy of the tendentious element is better than that of ordinary 4-nede rectangular clement. In some cases, it is even more effectual than high accuracy element.更多还原
