“…The convergence of reciprocal and expandable structures and their emergency use has led to the study of reciprocal frames as easy and fast to construct [28]. Interesting solutions have been suggested recently that use reciprocal arches [29]. The solution which is proposed to avoid the above-mentioned problems combines the advantages of expandable and reciprocal structures.…”

Expandable structures have certain qualities in terms of lightness and transportability which make them very useful as emergency buildings, a research line that is being developed by the authors. However, these structures have some disadvantages due to their reduced rigidity and great deformability, issues that could limit their use. This paper analyzes a reciprocal linkage that considerably improves one of the main problems of expandable structures, which is their lack of rigidity. The extremely strict geometrical conditions for this proposed linkage and the mechanical behaviour are examined. Two series of tests were carried out, with specimens formed by four bars supported reciprocally around the proposed linkage. In the first case, the bars had their ends simply resting on the base and in the second one displacement was restricted at their ends. Theoretical analysis and the experimental tests results are also included. The tests make it possible to define the failure patterns of the different elements of the linkages, bars or bolts. The theoretical models and the experimental results show that the proposed reciprocal linkages are highly effective. Tests of plane scissor meshes were also carried out using reciprocal linkages, showing a very significant reduction in their displacements.

Reciprocal Frame (RF) is a three-dimensional grillage structure that consists of mutually supported elements. In RF, whatever the composition that is built, the geometry should always have two members that are connected at a time. Moreover, at least three members should be connected to create a grid, but there is no limit for the maximum. In the research that has been done until today, the geometry of RF, form-finding issues, connections, structural behavior, fabrication methods were studied, but there is very limited number of studies about kinetic RF. In this study RF structures for single loop 3-, 4-, and 5-nexor configurations are analyzed in terms of their motion capabilities. The kinematic diagrams are drawn and their mobilities are calculated. Zero, single, and multi Degrees of Freedom (DoF) configurations are obtained. It has been found that the configurations with revolute joint series get minimum value and also it is not necessary to use as many joints as possible or joints with as many DoF as possible in the configuration to get maximum mobility value.
