UHPFRC Pavilion of 3-Dimentional Pentagon Tiling
The pavilion of ultra-high performance fiber reinforced concrete (UHPFRC) was fabricated in the form of 3-dimensional pentagonal tiling by wood formwork. Mann/McLoud/Von Derau discovered a 15th monohedral tiling convex pentagon in 2015 using a computer algorithm. Each unit of UHPFRC pentagon in 2-dimensional plane is the same but they are changed into different shapes in 3-dimensional vault type for the pavilion. To generate the 3-D shape two attractor points were located on the ground level. The transformation from 2-dimensional pentagonal tiling into 3-D vault was generated by Reino® and Grass hoper®. The data of formwork for units of UHPFRC was generated and then fabricated by wood. The fabrication of wood formwork relies on 6-axis robot cutting. To give structural stability of the vault the thickness of lower units was increased. The advantage of flow of UHPFRC enabled us to place UHPFRC into each of wood formworks. The lateral pressure of young UHPFRC was controlled by external screw jacks to avoid the deformation of wood formworks during curing. The connections between units relied on bolts and elastic pads. The connection behavior of bolts to transfer shear was guaranteed by the experimental program for strength.
