Algebraic tensegrity form-finding
This paper concerns the form-finding problem for general and symmetric tensegrity structures with shape constraints. A number of different geometries are treated and several fundamental properties of tensegrity structures are identified that simplify the form-finding problem. The concept of a tensegrity invariance (similarity) transformation is defined and it is shown that tensegrity equilibriu...
متن کاملA Marching Procedure for Form-finding for Tensegrity Structures
We give an algorithm for solving the form-finding problem, that is, for finding stable placements of a given tensegrity structure. The method starts with a known stable placement and alters edge lengths in a way that preserves the equilibrium equations. We then characterize the manifold to which classical tensegrity systems belong, which gives insight into the form-finding process. After descri...
متن کاملDYNAMIC RELAXATION OF TENSEGRITY STRUCTURES 553 DYNAMIC RELAXATION OF TENSEGRITY STRUCTURES A Computational Approach to Form Finding of Double-layer Tensegrity Grids
The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these...
متن کاملFinding tensegrity structures: Geometric and symbolic approaches
Two examples of a particular kind of form-finding problems are studied; given a set of fixed points, we ask for the position of an extra point such that a given framework admits a self-stress and hence a tensegrity structure can be built from it. We present two different approaches to solve these problems: The first method is geometric and hence more visual. A symbolic method is proposed as a s...
متن کاملSelf-assembly of 3D prestressed tensegrity structures from DNA
Tensegrity, or tensional integrity, is a property of a structure indicating a reliance on a balance between components that are either in pure compression or pure tension for stability. Tensegrity structures exhibit extremely high strength-to-weight ratios and great resilience, and are therefore widely used in engineering, robotics and architecture. Here, we report nanoscale, prestressed, three...
