KnitNervi - An actively bent, knitted formwork for ribbed concrete shells - Parametric Architecture

2 years ago 52

Knitnervi is simply a pavilion-scale objection of a ribbed factual ammunition constructed with a flexible formwork system. A bending-active gridshell serves arsenic falsework and reinforcement and is encased by CNC-knitted shuttering. Knitnervi task by the Block Research Group (BRG) astatine ETH Zurich and Dr. Mariana Popescu from the Faculty of Civil Engineering and Geosciences astatine Delft University of Technology, constructed for the accumulation “Technoscape: The architecture of engineers” astatine the MAXXI National Museum of 21st Century Arts successful Rome, Italy, 2022.

KnitNervi takes inspiration from Pier Luigi Nervi’s pioneering Palazzetto dello Sport to reimagine ribbed, thin-shell, reinforced-concrete construction. By proposing a operation strategy that eliminates the request for complex, wasteful molds, the task departs from the prefabrication and standardization paradigms that alteration expressive and businesslike factual shells.

The installation is simply a ribbed reinforced factual ammunition formwork strategy connected a flexible formwork system. The form’s highly articulated, doubly-curved geometry was discovered to enactment successful axenic compression with a hostility ringing astatine its perimeter. A bending-active gridshell serves arsenic the superior formwork operation arsenic good arsenic the integrated reinforcement of the last factual shell. KnitCrete encapsulates the expressive geometry, a CNC-knitted flexible stay-in-place shuttering.

The pavilion ammunition is 9.0m x 9.0m x 3.3m and has a covered country of 56.6 sqm. The value of alloy reinforcement is 533 kg, and the value of the formwork strategy is 10.8 kg/sqm.

Part of the Technoscape accumulation astatine the MAXXI, KnitNervi offers a roadmap for interdisciplinary co-development successful architecture, engineering, and construction. The ambition is to nurture a speech connected sustainable and structurally-efficient architecture successful the XXIst century.
