Parametric design of developable structure based on Yoshimura origami pattern

Abstract

Origami is an ancient art form and can be divided into rigid and non-rigid origami. Rigid origami is suitable for the design of building structures because the panels are not twisted and deformed during the folding process. Currently, rigid origami structures are generally built with steel. However, compared with natural, non-polluting wood, steel has a high energy consumption and a high environmental impact. Based on this situation, this paper designs a developable wooden building structure using the Yoshimura origami model. First, the Jacobian matrix method was used to analyze the degree of freedom of the basic unit of the Yoshimura origami pattern, following which the motion trajectory required by the target structure was obtained. Secondly, by analyzing the relationship between the plane angle α and dihedral angle θ, three interaction rules were obtained, and the formula for determining the structure size was established by using the plane angle α, dihedral angle θ, the number of valley folds n and the unit length l. Subsequently, two enhancement schemes, the quadrangle enhancement scheme and the triangle enhancement scheme, were proposed to increase the height of the structure. After comparing the deformation and failure types of origami structures based on Cross-Laminated Timber, a triangular reinforcement scheme was chosen to increase the height of the structure. Finally, a new connection method was developed that allowed the origami structure to be practically applied. This research demonstrates the possibility of developing a timber structure based on Yoshimura origami.

Large-scale modular and uniformly thick origami-inspired adaptable and load-carrying structures

“…As such, the pattern will have smooth deployment, compact storage, and good load-carrying capability, which make it a good candidate for adaptable civil structures. The kinematic deployment of thin and thick Yoshimura patterns has been studied by previous research [45][46][47][48][49] . However, these works did not present generic equations on developability and flat-foldability for degree-N thick origami vertices such as Eq.…”

Lateral Performance for Wood-Frame Shear Walls–A Critical Review

“…With the need for industrialization and the use of more eco-friendly materials, it was a wood hybrid structure that attracted much attention [73,74]. At present, the main forms of wood hybrid structures include concrete-wood and steel-wood hybrid structures [75].…”

Design and Development of Composite Plywood that Integrates Fire Resistance, Water Resistance and Wear Resistance

“…This method can also be used in veneer plywood to enhance its fire resistance, which affects its surface finishing performance to a certain extent and increase production investment. The surface wear resistance of plywood is usually achieved by attaching cladding materials or resin coating on the surface [23][24][25][26]. Due to changes in the processing conditions of plywood products (such as hot-pressing parameters, substrate types, etc.…”
