Les Cahiers de l'Ibois 3 / Ibois Notebook 3

Petras Vestartas, Sandra Vuilleumier

Before the twentieth century and concrete modernity, it was stone that embodied the “well built”. Could sustainable wood one day replace concrete as the archetypal material? Will it find a place on the scale of values that gives archi- tecture its referenc ...

Remarkable Color Gamut Enhancement of Dye Lacquers Using Corrugated Surfaces

Olivier Martin, Sebastian Mader

The visual appearance of any colorized object is usually determined by the spectral absorption of either pigments or dyes. One can however also colorize objects with structural colors that typically have an iridescent appearance, as seen on many beetles. T ...

A new method to design structures that adapt to loads via large shape changes

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

The construction industry contributes to more than a third of the global energy demand and consumes almost half of all mined material resources. It is thus important to include energy and material efficiency criteria for the design of civil structures. Ada ...
