Design-to-Fabrication Workflow for Raw-Sawn-Timber using Joinery Solver

Petras Vestartas

Currently, the Swiss timber industry in mountain areas largely exports unprocessed lumber and imports finished timber products due to the lack of digital tools. By using new digital design-to-production workflows, it is possible to investigate new building ...

Characterization of primary and aged wood burning and coal combustion organic aerosols in an environmental chamber and its implications for atmospheric aerosols

Satoshi Takahama, Nikunj Dudani, Amir Yazdani

Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM mass. We investigated the effect of aging on secondary organic aerosol (S ...

Experimental investigation of mesoscale variability of clear spruce mechanical properties in the radial direction

Thomas Keller, Anastasios Vassilopoulos, Alireza Farajzadeh Moshtaghin

The aim of this work is the investigation of mesoscale/local variability in mechanical properties of clear timber in the radial direction. Clear Norway spruce wood, Picea abies, was used for cutting specimens of different lengths with a small cross-section ...

Mitigation of Secondary Organic Aerosol Formation from Log Wood Burning Emissions by Catalytic Removal of Aromatic Hydrocarbons

Oliver Kröcher, Davide Ferri

Log wood burning is a significant source of volatile organic compounds including aromatic hydrocarbons (ArHC). ArHC are harmful, are reactive in the ambient atmosphere, and are important secondary organic aerosol (SOA) precursors. Consequently, SOA represe ...

Ecological response of tree saplings to simulated climate change along an elevational gradient (CLIMARBRE)

María Paula Sanginés De Cárcer

Switzerland will face higher temperature increases than the global average, which will have strong impacts on the mountain ecosystems. How tree species will respond to future climate change scenarios, and what mechanisms will they adopt, remains as a gap o ...

Integrally attached timber folded surface structures : geometrical, experimental and numerical study

Andrea Stitic

In structural engineering, folded surface structures present one of the concepts for construction of self supporting column free systems. They utilize structural benefits of folding to achieve material saving and improve structural efficiency. The folding ...

Characterization of Cold-Formed Steel Framed/Wood Sheathed Floor and Roof Diaphragm Structures

Dimitrios Lignos

The seismic in-plane response of cold-formed steel (CFS) framed diaphragm structures has not been the subject of extensive study. The information available specific to diaphragm design in the North American CFS design standard is based on limited experimen ...

Stochastic analysis of clear timber as a structural material

Alireza Farajzadeh Moshtaghin

Wood/timber has been widely used for house and bridge construction. It is a widely available natural material that necessitates low energy for the production, following simple processes. The environmentally friendliness, together with the low cost of raw m ...

Timber Folded Plate Structures – Topological and Structural Considerations

Yves Weinand, Andrea Stitic

This paper analyses the potential of different possible folded form topologies for generating timber folded surface structures. The main advantage of such structures lies primarily in the realm of ecology and sustainability. By offering an integral way of ...

CNC-fabricated dovetails for Joints of Prefabricated CLT Components

Yves Weinand, Benjamin Hahn, Christopher Werner Matthias Robeller, Paul Mayencourt

The widely available automated prefabrication in timber construction companies, as well as modern CAD software with application programing interfaces, allow for the design and production of increasingly geometrically complex building components. This devel ...

Heat, Electricity, or Transportation? The Optimal Use of Residual and Waste Biomass in Europe from an Environmental Perspective

Christian Ludwig, Bernhard Steubing

The optimal use of forest energy wood, industrial wood residues, waste wood, agricultural residues, animal manure, biowaste, and sewage sludge in 2010 and 2030 was assessed for Europe. An energy system model was developed comprising 13 principal fossil tec ...

Stratégies villageoises pour la gestion des paysages forestiers du Menabe Central, Madagascar

Introduction In order to reduce deforestation, the current attitude of conservation programmes and forest politics does no longer ban the local populations from the forests, because such measures present negative consequences for the communities. Today's t ...

GIS modelling of forest wood residues potential for energy use based on forest inventory data: Methodological approach and case study application

Edgard Gnansounou, Luis Alberto Panichelli

This paper presents an approach to perform geo-referenced estimations of forest wood residues availability for energy use based on forest inventory data integration into a GIS. Three different estimation methods are described. The first one evaluates bioma ...

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

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

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 ...

The influence of cattle activity on tree regeneration in wood-pastures

Charlotte Vandenberghe

Wood-pastures are semi-natural, highly biodiverse systems maintained by traditional extensive agriculture. They are used for grazing and timber. The shifting mosaics of grassland, shrub thickets and woodland patches in these systems are driven by large her ...
