The BamX! pavilion is composed of cylindrical deployable X-shells that meet at woven node connections to form a globally coupled, bending-active system. To find the optimal topology and geometry of the pavilion, we employ advanced numerical optimization techniques that incorporate a physics-based simulation of the bending and twisting behavior of the bamboo ribbons. The goal is to find the optimal ribbon crossing locations such that all external and internal forces are in a global balance, while the mechanical stress experienced by each ribbon is minimized. More details on the computational techniques developed at the EPFL Geometric Computing Laboratory can be found here.
