Being about a month away from moving my office into a Cross-Laminated Timber (CLT) building, I am of course interested in answers to this question. As it turns out, many recent research projects proved that CLT can evidently handle quite a bit of abuse (beyond regular day-to-day loading and use)! I may be biased, but this should really prove the point that CLT is a very capable and resilient building material.

So, without further ado – and for your viewing pleasure – here are three experiment videos that show how CLT can stand up to quite extreme loads and situations.

Earthquake

This seven-story CLT building shake table test was conducted in Japan as part of the SOFIE project by the Trees and Timber Institute of the Italian National Research Council and CNR-IVALSA.

More info can be found here and here.

Fire

This test on a stair shaft assembly was conducted by FPInnovations, Nordic, and the Ministry of Forestry in Quebec.

More info can be found here.

Explosives

This latest set of tests on blast resistance was conducted by WoodWorks in cooperation with the United States Forest Service, the Softwood Lumber Board, K&C and UMaine at Tyndall AFB in Florida.

More info can be found here.

Today’s opening of the T3 building in Minneapolis marks a spectacular milestone: The construction of the tallest contemporary heavy-timber building in the US so far! I am saying “so far” because as this trend continues, it will surely by surpassed in height very soon.

Completion of the T3 building continues a recent trend of larger, taller, and more technologically advanced wood buildings. This trend is helped along by a stronger environmental awareness, better recognition of this amazing building material by code officials, better education and awareness of the actual properties of wood, and the recognition by the public and developers alike that wood is simply beautiful and “feels good”.

Continuing my older posts about tall (and big) timber, here is a (likely incomplete) list of exemplary recent North American buildings in wood (all finished in 2016, I believe):

T3 – Minneapolis, MN

The seven-story, 220,000-square-foot T3 office building in Minneapolis’s North Loop district will become the tallest modern wood building in the U.S. when it opens tomorrow. Designed by Michael Green Architecture and the DLR Group, the T3—which stands for Timber, Technology, Transit—features cross-laminated timber (CLT) and nail-laminated timber (NLT) clad in weathering steel.

UBC Brock Commons Phase 1 – Vancouver, BC

A hybrid of mass timber products with concrete and steel components, the 18-story, 174-foot-tall structure will house 404 students.

Kern Center – Amherst, MA

The 17,000-square-foot center, designed by Bruner/Cott & Associates, is designed “to be entirely self-sustaining and meet the Living Status of the Living Building Challenge.”

Albina Yard – Portland, OR

Albina Yard in North Portland is the first building in the U.S. to use domestically produced cross-laminated timber (CLT) panels for a building-wide structural system

Common Ground High School – New Haven, CT

The school … offers public school students an innovative curriculum of urban agriculture combined with sustainable land-management practices. Last April it [opened] the doors to the nation’s first building to use cross-laminated timber (CLT) as a “stressed skin” assembly.’

What’s Next?

The Design Building at UMass Amherst is an 87,000 sf academic structure that features not only CLT and glulam in its structure but is a first in the US for a long-span wood-concrete composite floor system and CLT shaft shear walls.

The Design Building is almost completed! As you can see in the image below, the contractors are putting on the last touches and are hopefully giving my new office a good final vacuuming. We will be moving in there in January 2017 with an official building opening scheduled for later that semester. I will post more about this building soon.

I just came across this amazing 3D model of a round barn by Mike Beganyi, a timber framer and SketchUp modeler from Vermont. I know, it’s two years old, but check it out – and do it full-screen! It is such a great example of beautiful timberframing, excellent SketchUp modeling, and the use of my Sketchfab exporter.

The design is by our friends from Firetower Engineering.

I am trying something new: From now on, whenever I come across an interesting publication, I’ll post a link to my blog.

Abstract

Comparability of life cycle assessment (LCA) results based on different background data has long been debated. This is one of the main issues in building LCAs since buildings are complex products, which require multiple material data for the assessment. The objective of this study was to investigate numerical and methodological differences in existing databases related to building LCAs. The five databases selected were compared in terms of greenhouse gas (GHG) emission values in the material production phase of the three reference buildings, two wooden buildings with different frame types and a precast concrete framed building.

The results demonstrated that the databases show similar trends in the assessment results and the same order of magnitude differences between the reference buildings are shown by all the databases. It was also revealed that the numerical differences between the databases are quite large at some points and the differences originate from multiple data elements. The findings indicate the importance of the number of data and a clear statement of the bases of the values for comparative assessment. It would be more realistic to develop a reporting and communication system for LCAs rather than trying to unify the methodologies among the databases. An optimization of open information is significant for further development of LCA databases.

A recently-published report entitled “Summary Report: Survey of International Tall Wood Buildings” investigates various aspects related to the feasibility of tall wood buildings. This report, published by Forest Innovation Investment and the Bilateral Softwood Lumber Council, summarizes findings from surveys and interviews with key personnel involved in the creation of ten worldwide buildings, all of which are shown in the image above. The report focused on lessons learned, project insurance, project financing, and building operations and maintenance.

The authors relate the fact that most of these buildings are located in Europe to the existence of “a strong regulatory grounding in Europe that supports the use of low carbon content materials, renewable resources and energy efficiency in construction” and applaud the “strong ethos of collaboration” that exists there. Among all of the surveyed buildings worldwide, it was found that all involved parties had a commitment to a timber solution early on and were motivated based on innovation, market leadership and carbon reduction. Furthermore, the importance of pre-planning and collaboration was stressed.

While challenges exist, it was found that these projects “confirm that wood is a viable option for attaining safe, cost-equivalent, high-performing tall buildings.”

Yesterday was the opening of the exhibit “Urban Timber: From Seed to City” at the BSA Space of the Boston Society of Architects. Located close to Boston’s waterfront, this exhibit runs through the end of September 2014. So if you are in the area, don’t forget to drop by and check it out.

I was very happy to see the “new timber” reflected in this show: multi-story construction, cross-laminated timber, digital fabrication, sustainability benefits. Beautifully crafted displays show various recent case-studies of successful projects that used heavy timber as the structural material. Sustainable forestry is also explained, which then contrasts the renewable nature of wood products with mining and other non-renewable material manufacture processes.

Several physical and sometimes playful objects round out this great exhibit: The “four corners” set of mini-house shaped objects showcases how CLT can be used as material for floors, walls and inclined planes. The “coopered column” is a great example of a digital fabrication-driven assembly. And an object in the window at the bottom of the stairs bends wood to become both a screen and a seat.

Following are some impressions from the exhibit:
