本文提出了一种确定超静定桁架协调条件的新方法。它基于将桁架元件的角位移（旋转）与通过要求桁架结构的位移相容而获得的相应延伸相关联的方程，即，单值。这种新的角位移法对平面桁架可能是最有利的，但对三维结构可能不是这样。
This paper presents a new way of determining the compatibility conditions for statically indeterminate trusses. It is based on equations relating the angular displacements (rotations) of truss elements to the corresponding extensions obtained by requiring the displacements of the truss structure to be compatible, i.e., single valued. This new angular displacement method is likely to be most advantageous for planar trusses, but less likely so for three-dimensional structures.
