Shape optimization of compression structures

Finding the form of structures consisting primarily of compressive elements is not always an easy task. In order to facilitate the design process of compression structures, the shape of a mirrored tensile structure can therefore be adopted, based on the traditional tension- compression analogy. Adding kinematic constraints to the original definition of the force density method, fixing the length of each structural element, the procedure may be applied iteratively until given conditions are satisfied Fresl et al [1]. Beside fixed element length, different kinematic constrain can be used in the sense of wanted element forces. Moreover, for some elements one can define wanted length and for others target tensile force. This paper will investigate different forms of compressive structure as a result of form finding with tension - compression analogy using diverse kinematic constraints applied to the same layout of tension elements.
