Flexible geometry for bar structures

This article brings a geometric proposal which can be applied to the bar structures. The starting point is the substitution of the usual knots in a structural web by a system of combining the bars two by two, which is achieved by twisting the bars in each knot. The tensile forces that appear and the introduction of joints in each of these knots allow the transition from a rigid or undeformable geometry to a new "flexible" one leading to the possibility of one and the same structural web adopting different sizes while preserving its original geometric form. The article analyzes the geometric parameters to be used in order to obtain a coherent process.
