J.R.R. Tolkien, author of TheLord of the Rings, once wrote, “I longed to devise a setting in which the trees might really march to war.”
If climate change is a battle for Earth’s survival, then trees will be a vital army holding the line. When Tolkien imagined trees marching to war, he couldn’t have foreseen how relevant those words would one day be.
Forest Products Laboratory’s (FPL)Brian Brashaw was featured in an National Public Radio (NPR) segment about the soon-to-be world’s tallest timber building currently under construction in Milwaukee, Wisconsin. The Ascent building will boast 25 stories, 18 of which will be framed in mass timber. The upscale apartment complex is slated for completion in 2022. Right now, the cement foundation is being laid. Brashaw anticipates the Cross Laminated Timber (CLT) “to start flying,” or rather, construction crane hoisted pre-fabricated mass timber sections to begin installation in early summer 2021.
FPL is excited about its participation in helping the Ascent rise among the tallest modern wood structures in the world.
For the past 58 years, the third week of October has been deemed National Forest Products Week by Presidential proclamation. Here at the Forest Products Laboratory, every week is Forest Products Week, but we’re extra happy to celebrate this particular week with partners and the public, sharing all the good things trees provide.
To kick off the week, you can read a blog post below featured on the U.S. Forest Service and USDA blogs. Be sure to follow us on Twitter @fsWoodLab and #ForestProductsWeek to keep up with all the fun facts supporting what we already know: Wood is Good!
Forest Products Laboratory researchers conducted fire testing on a two-story cross-laminated timber (CLT) structure. Watch the short video below to see these one-bedroom apartments go up in flames, and to find out how CLT performed in the heat of the moment.
You can read more specifics about the tests in this previous LabNotes blog post, or if you’re really into the details and data, check out the full FPL general technical report.
New video footage has been released of blast testing performed on cross laminated timber (CLT) structures, and it’s quite a sight to see.
The Forest Products Laboratory, in cooperation with WoodWorks and the Softwood Lumber Board, led a second round of live blast testing in 2017 at Tyndall Air Force Base in Panama City, Florida.
The charges in the videos were large enough to potentially cause lethal injury, and the structures survived. The objective of these studies was to demonstrate the capability of CLT structures to resist airblast loads, thereby allowing the military to incorporate mass timber materials like CLT into their construction projects.
