Geometric Evaluation of Deployable Structures Using Parametric Modelling

This paper compares four systems of deployable scissor-like structures (also known as double layer grid-articulated joint systems). Its aim is to understand which of these require fewer elements to cover/span a given area. The results are assessed for five cases of the same area but with different geometry. As part of the research, two different methods have been used, contrasting the precision and convenience of each one simultaneously. On the one hand, we have used mathematical equations that allow us to quantify the amount of rods and joints needed in each system. On the other hand, in carrying out these evaluations, we have also used several digital models made with Grasshopper, a software that offers us tools to create algorithms. To conclude, we then evaluate the results obtained via both procedures.
