Curved Folded Plate Timber Structures

Yves Weinand, Hans Ulrich Buri, Ivo Stotz

This work investigates the development of a Curved Origami Prototype made with timber panels. In the last fifteen years the timber industry has developed new, large size, timber panels. Composition and dimensions of these panels and the possibility of mill ...

Pretreatment of Douglas fir wood biomass for improving saccharification efficiencies

Edgard Gnansounou, Juan David Villegas Gomez, Simone Chiesa, Rajeev Kumar Sukumaran

The main aim of this study was to analyze dilute acid pretreatment for the Douglas fir wood in order to improve the efficiency of hydrolysis with an ultimate aim to produce bioethanol. Compositional analysis of the untreated Douglas fir biomass revealed th ...

Innovative Timber Construction

Yves Weinand

In recent years, the necessity of using renewable resources and sustainable solutions in the building sector has become obvious, and interest in timber as a building material has revived. Novel timber-derived products, such as massif block panels, have eme ...

Selective degradation of wood lignin over noble-metal catalysts in a two-step process

Paul Joseph Dyson, Chenxu Zhao, Ning Yan, Cheng Wang

Direct conversion of lignin into alkanes and methanol was carried out in a two-step process (hydrogenolysis and hydrogenation) involving initial treatment of white birch wood sawdust with H2 in dioxane/water/phosphoric acid using carbon supported Ru, Pd, R ...

2008

In conjunction with Hans-Ulrich Buri’s research, this thesis project addresses the engineering part of the folded Origami structures. The material employed for this type of structure is not necessarily defined. Therefore metal, concrete and timber realisat ...

Iterative surface design for constructions based on timber panels

Yves Weinand, Ivo Stotz, Gilles Gouaty

The aim of our research is to develop a powerful tool for the generation and the fabrication of free-form architecture. Within the last years, architectural design has shown great interest in the design of new and complex geometries, commonly known as free ...

Evaluation of bamboo for building elements satisfying housing criteria

David Javier Guzman Chavez

Bamboo – identified as a Non Timber Forest Product (NTFP) – offering optimal mechanical properties for construction purposes, and at the same time little studied among contemporary building materials, is paradoxically most used in precarious housing. The u ...
