http://link.springer.com/10.1007/s10694-018-0714-2... [Fire Performance] [Journal Article] 2018
Colleen Wade, Michael Spearpoint, Charles Fleischmann, Greg Baker, Anthony Abu
There is an increasing desire to use more engineered timber products in buildings, due to the perceived aesthetics of timber and desire for more sustainable architecture. However, there are concerns about fire performance of these products especially in taller buildings. This has led to renewed research to understand the behaviour of timber surfaces in compartments exposed to fire. This paper describes a two-zone calculation model for determining the fire environment within a compartment constru...

Influence of openings on shear capacity of wooden walls
https://www.researchgate.net/publication/277819809... [Mechanical Performance] [Journal Article] 2005
Simona Klobčar
The proposed retrofit system deals with both problems at once; the new outer cross laminated timber walls stabilise a building against horizontal shear forces that are caused by earthquakes; on one hand the timber panels have a low mass and therefore dont contribute much to seismic forces, however they are very stiff on the other hand (Dujic, 2005) and provide high shear resistance. Crosslam timber panels (Dujic, 2005, Ceccotti, 2008, Blass et.al, 2004) are presented and the background of seismi...

Experimental and numerical investigations of cross-laminated timber elements at in-plane beam loading conditions
https://www.researchgate.net/publication/331224597... [Mechanical Performance] [Journal Article] 2019
Mario Jeleč, Henrik Danielsson, Vlatka Rajčić, Erik Serrano
Cross laminated timber (CLT) at in-plane beam loading conditions presents a complex stress state wherefore several failure modes and geometry parameters need to be considered in design. The work presented here includes experimental investigations of CLT beams for comparison and validation of an analytical model and design proposals previously suggested by the authors. All relevant failure modes are considered; bending failure and shear failure modes I, II and III. The main focus is, however, on ...

Using Small Diameter Logs for Cross-Laminated Timber Production
https://www.researchgate.net/publication/276339619... [Raw Materials] [Journal Article] 2015
Magnus Fredricksson, Peter Bomark, Olof Broman, Anders Gronlund
Sawing small diameter logs results in lower yield compared to sawing large diameter logs. This is due to geometry; fitting rectangular blocks inside an approximately cylindrical shape is more difficult for small than for large diameters. If small diameter logs were sawn in a way that follows the outer shape, yield would increase. The present study considers whether this can be done by sawing flitches into trapeze shapes. These can be glued together into rectangular products. Cross laminated timb...

Post-protection effect of heat-resistant insulations on timber-frame members exposed to fire
https://www.researchgate.net/publication/264455076... [Fire Performance] [Journal Article] 2012
Alar Just, Joachim Schmid, Jürgen König
In lightweight walls and floors, the load-bearing timber members are protected by cladding on the sides to form a divider between two fire compartments or to provide appropriate fire protection to the load-bearing members. The spaces between the timber members can be void or filled with insulation materials. Although a huge number of different insulation materials exist, the most commonly used material is mineral wool insulation. The existing design model for glass wool-insulated timber-frame co...

Moisture Response of Wall Assemblies of Cross-Laminated Timber Construction in Cold Canadian Climates
https://uwspace.uwaterloo.ca/handle/10012/6569... [Moisture/Durability] [Thesis/Dissertation] 2012
Robert Lepage
Wood is a highly versatile renewable material (with carbon sequestering properties), that is light in weight, has good strength properties in both tension and compression while providing good rigidity and toughness, and good insulating properties (relative to typical structural materials). Engineered wood products combine the benefits of wood with engineering knowledge to create optimized structural elements. Cross-laminated timber (CLT), as one such engineered wood product, is an emerging engin...

A Component Approach for the Hysteretic Behaviour of Connections in Cross-Laminated Wooden Structures
https://onlinelibrary.wiley.com/doi/abs/10.1002/eq... [Connectors] [Journal Article] 2013
Giovanni Rinaldin, , Claudio Amadio, Massimo Fragiacomo
In this paper, a numerical model to estimate the dissipative capacity and describe the cyclic response of cross‐laminated (X‐lam) timber buildings is presented. The connections between panels and to the foundation (metal hold‐downs and angle brackets, and screwed connectors) are modelled with nonlinear hysteretic multispring elements taking into account the strength interaction between different degrees of freedom according to a predefined domain. The timber components (solid X‐lam floors and wa...

Wood is a pure, sustainable, renewable material. The increasing use of wood for construction can improve its sustainability. There are various techniques to assemble multi-layer wooden panels into prefabricated, load-bearing construction elements. However, comparative market and economy studies are still scarce. In this study, the following assembling techniques were compared: laminating, nailing, stapling, screwing, stress laminating, doweling, dovetailing, and wood welding. The production cost...

CLT Plates Under Concentrated Loading – Experimental Identification of Crack Modes and Corresponding Failure Mechanisms
https://link.springer.com/chapter/10.1007%2F978-94... [Mechanical Performance] [Book/Book Section] 2014
Georg Hochreiner, Josef Füssl, Josef Eberhardsteiner, Simon Aicher
Since wood products for structural elements, such as cross-laminated timber (CLT), have gained importance in the building sector, the need for appropriate and reliable design codes has become essential. For this reason, this work focuses on global failure mechanisms and the corresponding evolution of different crack modes in CLT plates, depending on geometric and/or material related influence quantities. Therefore, plate-bending experiments on 3- and 5-layered CLT-plates were carried out. In add...

Overview of a Project to Quantify Seismic Performance Factors for Cross Laminated Timber Structures in the United States
https://link.springer.com/chapter/10.1007%2F978-94... [Seismic Performance] [Book/Book Section] 2014
M. Omar Amini, John van de Lindt, Shiling Pei, Douglas Rammer, Philip Line, Marjan Popovski
Cross-laminated Timber (CLT) has been extensively used in Europe and is now gaining momentum in North America; both Canada and more recently the U.S. Construction projects have shown that CLT can effectively be used as an alternative construction material in mid-rise structures and has significant potential in commercial and industrial buildings. In the United States, the CLT system is not currently recognized in seismic design codes and therefore a seismic design can only be performed through a...

Evaluation of North American Vibration Standards for Mass-Timber Floors
https://link.springer.com/chapter/10.1007%2F978-3-... [Vibration/Acoustic Performance] [Journal Article] 2014
Joshua Schultz, Benton Johnson
Mass-timber is an emerging building technology created by using structural adhesives to laminate layers of dimensional lumber together to create large ‘timber’ panels. These panels can be used as structural building elements in floors and walls. However, due to relatively large stiffness-to-mass ratios and low inherent damping, optimized timber floors can be vibration controlled even at spans of 3 m. There are several current North American vibration standards that can be applied to timber floor...

Assessing the Fire Integrity Performance of Cross-Laminated Timber Floor Panel-To-Panel Joints
http://catalogue.library.carleton.ca/record=b38594... [Fire Performance] [Thesis/Dissertation] 2016
Christian Dagenais
During the past few years, a relatively new technology has emerged in North America and changed the way professionals design and build wood structures: Cross-laminated Timber (CLT). CLT panels are manufactured in width ranging from 600 mm to 3 m. As such, fastening them together along their major strength axis is required in order to form a singular structural assembly resisting to in-plane and out-of-plane loading. Typical panel-to-panel joint details of CLT assemblies may consist of internal s...

https://www.researchgate.net/publication/270875737... [Fire Performance] [Conference Paper] 2015
Alastair Bartlett, Rory Hadden, Luke Bisby, Angus Law
The use of engineered timber products such as cross-laminated timber (CLT) is of increasing interest to architects and designers due to their desirable aesthetic, environmental, and structural properties. A key factor preventing widespread uptake of these materials is the uncertainty regarding their performance in fire. Currently, the predominant approach to quantifying the structural fire resistance of timber elements is the charring rate, which allows estimation of resid...
