Success factors in the realization of large ice projects in education

Abstract

There has been a long tradition in making ice structures, but the development of technical improvements for making ice buildings is a new field with just a handful of researchers. Most of the projects were realized by professors in cooperation with their students as part of their education in architecture and civil engineering. The following professors have realized ice projects in this setting: Heinz Isler realized some experiments since the 1950s; Tsutomu Kokawa created in the past three decades several ice domes in the north of Japan with a span up to 25 m; Lancelot Coar realized a number of fabric formed ice shell structures including fiberglass bars and hanging fabric as a mold for an ice shell in 2011 and in 2015 he produced an fabric-formed ice origami structure in cooperation with MIT (Caitlin Mueller) and VUB (Lars de Laet). Arno Pronk realized several ice projects such as the 2004 artificially cooled igloo, in 2014 and 2015 dome structures with an inflatable mold in Finland and in 2016–2019, an ice dome, several ice towers and a 3D printed gridshell of ice in Harbin (China) as a cooperation between the Universities of Eindhoven & Leuven (Pronk) and Harbin (Wu and Luo). In cooperation between the University of Alberta and Eindhoven two ice beams were realized during a workshop in 2020. In this paper we will present the motivation and learning experiences of students involved in learning-by-doing by realizing one large project in ice. The 2014–2016 projects were evaluated by Sanders and Overtoom; using questionnaires among the participants by mixed cultural teams under extreme conditions. By comparing the results in different situations and cultures we have found common rules for the success of those kinds of educational projects. In this paper we suggest that the synergy among students participating in one main project without a clear individual goal can be very large. The paper will present the success factors for projects to be perceived as a good learning experience.

Experimental Investigation of Unconfined Compressive Properties of Artificial Ice as a Green Building Material for Rinks

“…In the case of frictional coefficient µ, 0.35 is adopted on the base of the assumption in [42]. Using these parameters, the theoretical critical transitional strain rate is calculated as 4.6 × 10 −4 s −1 based on Equation (5), which is also consistent with the transitional strain obtained in our experiments.…”

“…Thus, a fundamental understanding of the mechanical behavior of artificial ice in the rink is required to prevent the artificial ice sheet failure in service. Notably, ice, as a common sustainable and green building material that has been increasingly employed in the construction of landscapes or shelters [5][6][7] in cold regions, has been studied by several researchers. However, for the artificial ice as a building material in winter sports rinks, the mechanical properties remain unclear.…”
