French Triumph: How Notre-Dame Fully Traced Oaks in Rebuild!
In total, more than 1500 French Oak trees have been used to fully restore the roof, the spire, the internal nave and choir, with the project paying tribute to the astounding craftsmanship of the cathedral’s original builders and ensuring that the centuries-old art of hand-fashioning wood lives on.
“We want to restore this cathedral as it was built in the Middle Ages,” according to the late Jean-Louis Georgelin, who in 2019 said, “It is a way to be faithful to the [handiwork] of all the people who built all the extraordinary monuments in France.”

Next-Gen Timber Buildings: Taller, Safer and Self-Centring!
Global engineers are making huge strides in developing new building systems to make mid-rise and high-rise towers resilient to quake activity.
Self-centring building systems are key to driving the next generation of mid-rise and high-rise construction—not just in single-storey buildings but also in traditional multi-storey and assembly-line prefab construction.
That is according to new research, known as Self-centering mass timber structures: A review on the recent research process, published in the journal Engineering Structures, which reports that earthquake engineers are now making major strides in developing new mass timber systems that not only save lives but also minimise reconstruction costs.

World’s Biggest 3D Printer Builds (Almost) Anything from Wood!
Introducing the Factory of the Future 1.0 (or FoF 1.0) now used to construct houses, bridges, military installations and maritime vessels.
The US Government is investing millions into developing supersized 3D printers to build the next generation of infrastructure—for national security and use in affordable housing, bridge construction, ocean and wind technology, and maritime vessel fabrication.
These printers now use “wood dust”—sourced from the US’s most abundant forests—to manufacture greener and more cost-effective building materials.

Effect of roof to wall connection stiffness variations on the load sharing and hold-down forces of Australian timber-framed houses
“Roof to wall connections (RWCs) play a major role in wind load sharing and load transfer of timber-framed houses. The lack of coherence in the load sharing and load transfer can cause premature failure of timber-framed houses. Thus, it is essential to provide RWCs with adequate strength and stiffness, to ensure the dynamic roof wind loads are adequately shared and transferred through the structural system to the foundations. Typical construction defects in RWCs (i.e. missing nails) reduce the stiffness of the RWCs, introducing discontinuities in load paths, contributing to total roof failure under windstorms. This study combines realistic spatially and temporally varying wind loads, captured from model-scale wind tunnel-studies, with a validated finite element model of the roof structure, that accurately describes the load sharing through the structural system and evaluate the effect of RWC stiffness variations and realistic wind loading variation on the load sharing and hold-down forces of Australian contemporary timber-framed houses.”

How to Bend Wood
“From its starting to point as a tree to its product form as a beam or piece of furniture, wood used in architecture and interior design goes through several stages and processes. A renewable resource and popular traditional building material, wood is also often cited as a promising construction material of the future, one that is suitable for the new demands of sustainability. But unlike concrete, whose moulds can create even the most complex curves, wooden architecture most commonly uses straight beams and panels. In this article, we will cover some techniques that allow for the creation of curved pieces of wood at different scales, some of which are handmade and others of which seek to make the process more efficient and intelligent at a larger scale.”

Multi-level Roof Structure
“When we were commissioned, the client asked us to create advanced architecture that expands the horizons of what can be achieved with wood. From this, we drew up the design for this building, with its unique timber structure,” explains Fumie Horikoshi, architect and co-owner of the Tokyo-based practice Uenoa”
