The roof of the Denver International Airport terminal (above) is a tensioned fabric structure designed by Horst Berger, a civil engineer famous for his large-scale fabric projects. This roof employs double-curved "minimal surfaces" that are characteristic of soap films (see From Physics Research).
- Visit Tensile Structure to learn more about this kind of construction.
- See this article from Structure magazine for information about Berger's career and numerous photos of his work.
