Inflatable Membrane Structures: Pneumatic Systems in Nature and Technology

Human technology has not yet equaled the highly complex and efficient construction principles of nature, as shown in the example of a dragonfly wing. Multifunctionality is a common principle of biological structures. Through the analysis of biological light weight structures and structure system using Finite Element Analysis and material analysis we can make quantitative statements regarding their constructive efficiency. This research focuses on the relationships between the structure system, (a tubular folded plate, a hydraulic system and a membrane) and the material of the dragonfly wing (nature) and makes the connection to new materials and smart structures used in engineering (technology). The definition for light-weight construction is the optimization of the path of forces towards the reduction of the constructed volume. This research will examine to what extend adaptively affects the optimal geometry and efficiency of a structure. The goal is to define a set of structural principles, and to make those principles applicable for architects and engineers.
