    To address the urgent challenges faced by the construction industry of reducing carbon emissions while meeting the demand for new floor area, innovating floor systems offers high potential as slabs are structurally highly inefficient and mass dominant. Unreinforced vaulted floor systems offer a promising strategy through their geometric stiffness. However, the drawback commonly lies in the expensive and wasteful formworks for such non-standard geometry, furthermore often relying on digital fabrication, which is not available in emerging markets where there is the highest need. In response, this research introduces a low-tech, low-cost, material-efficient, lightweight, compactly transportable, rapidly deployable, self-supporting, and reusable formwork solution. Unfoldable curved-creased bending-active plates with textile hinges enable the in-situ construction of unreinforced corrugated fan-vaulted floor systems. The curved creases provide shape control, while the corrugations provide stiffening and translate into concrete rib articulations to enhance material efficiency. This paper focuses on validating the system through a demonstrator. The system, its co-design methods, and its fabrication and construction are presented. By employing structural geometry for both formwork and resulting shell floor, as opposed to wasteful moulds and inefficient slabs, the system could reduce the environmental impact of the construction industry.

  • Path to form finding: the formative years of Heinz Isler
    Item type: Conference Paper
    Beckh, Matthias; Schützeichel, Rainer (2017)
    Proceedings of IASS Annual Symposia
    The paper investigates the formative years of the influential Swiss shell engineer Heinz Isler in two respects: Firstly, the influence of Isler’s early steps as student and as assistant at Pierre Lardy’s chair at ETH Zurich on his later understanding of the design of concrete structures will be examined. On the basis of two projects presented at conferences in 1955 and 1957, the paper will secondly shed light on Isler’s usage of models as either tools for measuring or – characteristic for the engineer’s innovative approach – for “naturally” designing shapes of shells.
