Cross-laminated timber (CLT) is a new panelized mass timber product that is suitable for building tall wood buildings (higher than eight stories) because of its structural robustness and superior fire resistance as compared with traditional light-framed wood systems. A number of tall CLT buildings have been constructed around the world in the past decade, and taller projects are being planned. The energy efficiency of this emerging building type was evaluated numerically in this comparative stu...

P. D. Kremer, M.A. Symmons
AbstractThe present paper is the first to conceptually assess the viability of mass timber construction (MTC) as an alternative construction material/method in Australia. It fulfills an identified need to examine an innovative construction process providing much needed information concerning the technologies current position and future disruption to traditional construction methods. A common tool used in business management studies, the PESTEL model, Political, Economic, Social, Technological, E...

Experimental tests on cross-laminated timber joints and walls
https://www.icevirtuallibrary.com/doi/pdf/10.1680/... [Mechanical Performance] [Journal Article] 2015
Georg Flatscher, Katarina Bratulic, Gerhard Schickhofer
As a product, cross-laminated timber exhibits widely linear-elastic behaviour (except for compressive stress) and a tendency to have brittle failure mechanisms. Therefore, especially at dynamic loadings (e.g. earthquakes), the behaviour of cross-laminated timber structures is highly dependent on the connections used. Based on several singlejoint and wall tests performed monotonically as well as cyclically, this paper provides improved insight into the behaviour of different joints that make up c...

Prediction of compressive strength of cross-laminated timber panel
https://link.springer.com/content/pdf/10.1007%2Fs1... [Mechanical Performance] [Journal Article] 2015
Jung-Kwon Oh, Jun-Jae Lee, Jung-Pyo Hong
Compressive strength of cross-laminated timber (CLT) is one of the important mechanical properties which should be considered especially in design of mid-rise CLT building because it works to resist a vertical bearing load from the upper storeys. The CLT panel can be manufactured in various combinations of the grade and dimension of lamina. This leads to the fact that an experimental approach to evaluate the strength of CLT would be expensive and time-demanding. In this paper, lamina property-ba...

The Value Proposition for Cross-Laminated Timber

Pablo Crespell,Chris Gaston
As part of Bio-pathways II the team was asked to look in detail at the market for some of the technologies on the list. This was phrased as a deep dive and it was decided that the first deep dive should be made on Cross-laminated Timber (CLT) as it was one of the more promising technology options. This document contains that deep dive presented in a NABC format (Market Needs, Approach to Market, Benefits of the Products and Competition). CLT is a cost-competitive wood-based solution that compl...

XLam to open Australias first cross laminated timber manufacturing plant in Albury-Wodonga
http://www.abc.net.au/news/2016-05-24/albury-wodon... [Markets] [Magazine/Newspaper Article] 2016
Erin Somerville
Albury-Wodonga, on the Victorian/New South Wales border, is set to be home to Australias first cross laminated timber (CLT) manufacturing plant. CLT is fabricated by bonding together timber boards with structural adhesives to produce a solid timber panel, with each layer of the panel alternating between longitudinal and transverse layers. Alternating the grain directions of each layer reduces many weakness found in other timber products. The $25 million XLam operation is expected to create up t...

An Overview of CLT Research and Implementation in North America

Shiling Pei, Douglas Rammer, Marjan Popovski, Tom Williamson, Philip Line, John W. van de Lindt
Although not yet seen as common practice, building with cross laminated timber (CLT) is gaining momentum in North America. Behind the scenes of the widely publicized project initiatives such as the Wood Innovation Design Centre Building in Canada and the recent U.S. Tall Wood Building Competition, substantial research, engineering, and development has been completed or is underway to enable the adoption of this innovative building system. This paper presents a brief overview of the current statu...

Build Better, Stronger, Faster with CLT

Joyce El Kouarti
One of these products, cross-laminated timber, also known as CLT, offers an opportunity for raising tall buildings with wood, opening up a completely new market for wood products. Because of its high strength, CLT is an advantageous alternative to traditional building materials such as concrete, masonry, and steel. Because CLT panels resist compression, they are well-suited for building multistory structures, especially mid-rise buildings. When a seven-story CLT building was tested on the world...

In the 20 years since its invention in Europe, cross-laminated timber (CLT) has become a widely used construction material in parts of the old continent and has started to attract global attention. CLT possesses numerous advantages as a construction material, including its superior structural and environmental performance, as well as the speed and efficiency with which CLT buildings can be erected. In this study, European engineers were surveyed to learn about their current level of awareness of...

KLH
The Holme Lacy Campus Agricultural Workshop is a new addition to Herefordshire and Ludlow College. Unusually for an agricultural building, the workshops structure was formed in cross-laminated timber from KLH (as opposed to conventional steel). This pre-fabricated, sustainable and attractive self-finished material allowed for a rapid on-site build, which was important as the College had a limited window of construction opportunity....

Researchers at the Forest Products Laboratory (FPL) are back to work using the debris launcher in the Engineering Mechanics and Remote Sensing Laboratory. The debris launcher is an air cannon that fires two-by-fours at 100 mph to replicate what could happen in a house or any wood structure during a tornado. The equipment has been used frequently over the past several years, most recently to test the viability of tornado safe rooms constructed of wood. This time, researchers are using the cannon ...

A case study to investigate the life cycle carbon emissions and carbon storage capacity of a cross laminated timber, multi-storey residential building
http://centaur.reading.ac.uk/33178/... [Environmental Performance] [Others] 2013

Forests are a store of carbon and an eco-system that continually removes carbon dioxide from the atmosphere. If they are sustainably managed, the carbon store can be maintained at a constant level, while the trees removed and converted to timber products can form an additional long term carbon store. The total carbon store in the forest and associated ‘wood chain’ therefore increases over time, given appropriate management. This increasing carbon store can be further enhanced with afforestation...
