An efficient method is developed for the analysis of scissor-like foldable structures. The stiffness matrix of a unit of such structure known as "duplet" is derived and incorporated in an standard stiffness method. A computer program is developed and many examples are studied. The results are compared to the analysis using uniplet elements. Substantial improvement is obtained through the introduction of duplets in place of the use of uniplets. Foldable structures with cable elements are also considered.
