Origami inspired Deployable Structures, Analysing through Case Studies and Generating Iterations using Parametric Modelling Tools.

Abstract

Transformable structures have been a part of architecture since the early ages. From nomads to retractable roofs for stadium, transformable structures have many diverse applications and advantages. These structures are classified using various structural system and form generation techniques. Origami inspired deployable structures have advent scope in architecture. These structures are conditioned to adapt to the changing environment and the needs of the user. Origami, originally used as a form of art, has a lot of applications because characteristics of the form. The deployable nature of origami patterns that allow the designers to make forms that can be reduced and transported by contracting the entire structure into a smaller volume. Origami provides a cognitive approach to structural stability and form finding. The geometry and folds give stability to the form which leads to creation of self-supported forms which are aesthetically pleasing. It is necessary to understand the behavior of these deployable forms. The dissertation focuses on understanding the connections between the modules and the ground. The parameters are generated using various precedent case studies and literature which can further be useful to generate iterations. These parameters are used to create varied forms by modulating different patterns Parametric modelling or computational aided tools have made it easier for the designers to derive these forms by undulating the patterns and exploring different kind of forms. Plugins of Rhinoceros, such as Grasshopper with Kangaroo are used to derive iterations using different folding patterns. This paper focuses on the aspect of different structures inspired by origami that possess deployable characteristics. It focuses on how the origami patterns are modulated to generate different forms, and determining the most stable deployable state for the chosen patterns. It later focuses on analyzing these patterns using the volume of the structure generated using the folded state. Later, most suitable pattern is used to create different spans using different modules and developing a relationship between the module of the pattern, number of tessellations, geometry, height and habitable space of the structure
