摘　　要：本文应用虚功原理建立以剪力流为未知量的线性代数方程组，由此可直接解得多室闭口薄壁杆件自由扭转的剪力流．This article intends to establish linear algebraic equations with shearing force flow asunknown quantity using the principle of virtual work. Hence the shearing force flow of themulticell closed thin walled member under pure torsion is evaluated directly.

关 键 词：多室闭口薄壁杆件 自由扭转 虚功原理 剪力流
