The correctness and validity of this method were made clear by the mechanism synthesis of the octahedron variable geometry truss. 八面体变几何桁架机构综合实例表明了该方法的正确性与有效性。
For a complanate parallel chords truss, the axial forces of a member can be solved by the shear-diagram and two simple expressions. 借助与桁架对应的梁的剪力图和弯矩图根据两个关系式可直接求出一般平面平行弦桁架任一根杆件的轴力。
