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 mortar-timber and timber-timber cyclic friction in timber floor connections of masonry buildings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

The seismic performance of buildings depends critically on the stiffness and strength of storey diaphragms. Whilst for modern reinforced concrete or steel structures the connection between floors and lateral resisting members is often assumed as monolithic ...

Modern timber design approaches for traditional Japanese architecture: analytical, experimental, and numerical approaches for the Nuki joint

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting

This work fully investigates a specific timber joinery connection via experimental, analytical, and numerical methods. The selected joint is the Nuki joint: a mortised column with through-beam tenon. The experimental approach takes advantage of digital fab ...

Reconsidering traditional timber joinery for sustainable structures

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting

Timber construction plays an important role in architectural history, in modern construction methods and in sustainable design, for which wood-only joinery techniques have been used for centuries. Traditional joinery typologies are the product of successiv ...

Ductility of adhesively bonded timber joints

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

In the field of timber engineering, adhesive bonding remains a promising, though poorly developed, joining technique that may increase the structural stiffness and capacity of timber joints and structures. Selecting ductile adhesives may further allow to c ...

A 3D Cutting Method for Integral 1DOF Multiple-Tab-and-Slot Joints for Timber Plates, using 5-axis CNC Cutting Technology

Yves Weinand, Christopher Werner Matthias Robeller

Integral Mechanical Attachment (IMA) uses features in the form of components for their connection. In addition to the transfer of forces, locator features are used as integral assembly guides. Prismatic, single-degree-of-freedom (1DOF) joints only allow fo ...

Influence of surface shapes on the mechanical behaviour of friction welded wood bonds

Yves Weinand, Bernhard Stamm, Benjamin Hahn

Friction welding of wood is a fast and adhesive-free bonding technology for the production of timber joints with good mechanical characteristics making this type of connection interesting for applications in timber construction. However, the moisture stabi ...

Placing unprecedented recent fir growth in a European-wide and Holocene-long context

Jed Oliver Kaplan

Forest decline played a pivotal role in motivating Europe's political focus on sustainability around 35 years ago. Silver fir (Abies alba) exhibited a particularly severe dieback in the mid-1970s, but disentangling biotic from abiotic drivers remained chal ...
