The geometric stiffness matrix is composed by the effect of axial force, bending moment and bimoment.
其中几何刚度矩阵由轴向力、双向弯曲和截面翘曲的影响组成。
A new point is put forward that transverse bimoment has different influence on the two kinds of cross section thin-walled beams, and on their St-Venant principle conditions.
同时对外载等效中经常出现的横向双力矩这一广义力进行研究，指出它在开口和闭口薄壁梁约束扭转问题中和圣维南原理适用条件中分别占有不同的地位。
