An experimental Carbon-Fiber-Reinforced Polymer (CFRP) shell pavilion of a complex shape is designed parametrically through Grasshopper for Rhino with the architectural idea of leaves curling in intermittently intense winds to protect their structural integrity. The interplay of concave and convex surfaces directs the airflow. Moreover, foldable elements - spikes (reminding of leaves) are created on the surface of the weather shelter, which further influences the wind flow. The form-finding of the pavilion, subjected to the wind loads of 26 m/s (the fundamental value of the basic wind velocity for Slovakia), is performed in Grasshopper, combining the structural engineering tool Karamba 3D and the optimization plug-in Galapagos into one design loop. Digital FEM simulations performed through Karamba 3D enable a swift structural design evaluation supplying instant results for Galapagos. New-generation architectural designs can emerge from the experimentation with bio-inspired architecture and incorporating composite materials, leading to lightweight, shape-adaptive, long-span, elegant architectural structures that can withstand high wind speeds and, if carefully designed, even reduce the wind surface pressure.
