Each such beam is subjected to the externalloads that normally act upon it, together with the two redundant moments at its ends.
每一根这样的梁承受垂直作用于其上的外荷，以及两端的两赘余弯矩。

The general formulae for the analysis of stresses and displacements in an elastic layered systems subjected to externalloads are derived in this paper.
本文首先导出了在圆形分布荷载作用下层状弹性体系应力与位移计算的一般性公式。

Thus the whole space structure is divided into many planar structures bearing externalloads together and structures perpendicular to the plane share no loads.
