This paper presents a research study on a geometry and mechanism of origami for generating a deployable tessellation structure that will be tested as a large span structural system. The research explores a combination of methods for understanding the structural limitations of deployable origamic geometry by using geometric scripting with a parametric system and finite element analysis tools. This combination of methods allows deployable origamic geometry structures to be evaluated at various scales which provides information on how to optimize the geometry for a given scenario. Analog models based on biological inspirations were initially produced for studying the origamic deployment mechanism followed by a process that translated the model into a scripting based form generation using a parametric system to propagate different permutations of the same origami family. The workflow requires interoperability between the parametric system (Grasshopper/Rhino), Excel, and finite element analysis tool (LS-DYNA). The research investigates the possibilities of extracting geometric and mechanical principles of microstructure for its application to a larger scale structure as an architectural element. A recent paper by the authors discussed the general process from biological inspiration to structural evaluation of the selected origami structure (see Baerlecken et al. [1]). This paper continues the discussion with more additional information related to geometric principles of the selected origami for the case study and the technical details on the interoperability between the parametric and the structural system.

The relation between texture, pattern and massing is a fundamental question in architecture. Classical architecture, as Leon Battista Alberti states in De Re Aedificatoria, Book VI, Chapter 2, is developed through massing and structure first; texture is added afterwards to give the bold massing and structure beauty [1].This hierarchy has of course been challenged throughout architecture history. This paper will provide a different thinking of the relationship of massing and texture in Islamic Architecture from a digital point of view. An analysis of Islamic patterns challenged this relationship in Islamic architecture. Digital design and fabrication methods for a series of studies and an installation were used to respond to the findings of the analysis. ᭤ Figure 1: Islamic pattern constructed using a rectangular tiling system.

This paper presents a concept of folding as a formgenerator for a structural system that allows the ability to deploy large spanning structures.The presented approach studies the embedded kinetic possibilities of folded structures and focuses on a parametric modeling process that allows structural performance evaluation of different types of the same origami family in order to optimize the geometry for a given scenario.The workflow between scripting based form generationwithin Rhinoceros and Excel -and LS-DYNA is presented in detail. Additionally, within the context of an architectural project we discuss the question of scalability from a thin microstructure to a thickened roof structure.

Michalatos and Kaijima underline in their paper ‘Structural Information as Material for Design’ (2007) the importance to approach an informed design consistency and respect the “criteria of efficiency, architectural intentions as well as intrinsic properties of the geometry” rather than simple structural optimization of a certain design. Our paper investigates this consistency between architecture and structure within the framework of parametric modeling, which requires architects, engineers and constructors to re-evaluate the feedback loop between how things are designed and constructed. As Mario Carpo (2008) points out CAD and CAM technologies have overthrown the “Albertian Paradigm” which claims that architects should not make things, but should just design and annotate them. As digital tools can be used to design and fabricate at the same time, CAD-CAM technologies have already started to bridge the gap between designers and makers. One of the most influential form related factors on the lighting situation inside the building is – due to its shading behaviour – the dimension and position of the supporting structure of the façade. It is important to investigate these positions at the beginning in-depth, since they serve as hypothesis for the entire planning process. In order to compare a catalogue of various design approaches and different designs in a timely manner, a parametric model has been built defining the rough form of the design.

This paper investigates making as a process that brings together diverse materials and combines their flow in anticipation of what might emerge. Ingold calls this approach the textility of making, which gives priority to the formation of materials as a process, in which form is generated through interventions within fields of forces and currents of materials and not through a predefined notion of an ideal outcomei, opposes the Aristotelian "hylomorphic approach" which focuses on final products.
