Experimental investigation of fire resistance of GLT beams
https://www.researchgate.net/publication/340545214... [Fire Performance] [Journal Article] 2020
L. Kucíková, T. Janda, M. Šejnoha & J. Sýkora
Mechanical and fire loading play together with geometric and material properties of glued laminated timber beams a decisive role in theoretical investigation into the time-dependent fire resistance of these elements. This is a multidisciplinary problem including heat conduction, water evaporation, internal gas pressure evolution, pyrolysis, volume change, etc. If properly calibrated, such complex models should allow us to forecast the evolution and shape of the charred or zero strength layer. It...

Non destructive evaluation of stiffness properties of cross-laminated solid wood panels
https://www.researchgate.net/publication/278672731... [Mechanical Performance] [Conference Paper] 2010
Arne Gülzow, René Steiger, Daniel Gsell
Cross-laminated timber (CLT) is a panel-shaped engineered wood product, assembled of layers of lamellas (mostly softwood) with perpendicular orientation of the grain direction. In contrast to other panel-shaped engineered wood products, CLT is not used as components of structural elements, but rather as load bearing plates and shear panels. The design of CLT used as load-bearing plates is often governed by serviceability criteria like maximal deflection and vibration susceptibility. Hence, predi...

Lindsay Ranger, Christian Dagenais
The objective of this work is to generate fire performance data for NLT assemblies to address gaps in technical knowledge. This project aims to study how the size of gaps between NLT boards might affect charring of an assembly and its overall fire performance. This research will support designers and builders in the use of mass timber assemblies in larger and taller buildings, by ensuring fire safe designs....

A Study of the Viability of Cross Laminated Timber for Residential Construction
http://kth.diva-portal.org/smash/record.jsf?pid=di... [Economics/Costs] [Thesis/Dissertation] 2018
Max Smyth
This report presents an overview into cross laminated timber (CLT) as a construction material and how it compares to traditional methods of construction. CLT is also examined in the context of a move to off-site manufacturing (OSM) and a greater emphasis on sustainability in the construction sector. In this context it is found to perform well with mass timber products such as CLT being the only carbon negative building materials capable of building mid and high-rise buildings. The barriers and ...

Numbered are the days of stodgy office buildings and sterile cubicles, now giving way to large open floor plans characterized by natural materials, exposed timber, and ample areas for shared workspace and collaboration. Sometimes referred to as superwides for their spacious floor plates, there is a rising demand for these tenant-winning offices as businesses discover employees are more productive when they intermingle, unobstructed, on the same floor....

When you construct hotel lodging for the U.S. Army, not only do the buildings need to be comfortable and well-equipped, they need to be blast resistant to mitigate any potential security risk. It’s a tall order that mass timber is proving able to meet, its performance on par with steel-stud wall construction....

Bolt-Bearing Yield Strength of Three-Layered Cross-Laminated Timber Treated with Phenol Formaldehyde Resin

Wengang Hu, Jilei Zhang
The effect of impregnation treatment of low molecular weight phenol formaldehyde (MWPF) resin on the bolt-bearing yield strength (BBYS) of a three-layered cross-laminated timber (CLT) composed of two face layers of southern pine (Pinus taeda) and one core layer of sweetgum (Liquidambar styraciflua) was investigated together with two additional factors of material type and loading direction. Experimental results indicated that the amount of low MWPF resins penetrating into sweetgum was more than ...

ArticlePDF Available Comfort level oThermal comfort is a key criterion to be considered to ensure a healthy indoor environment for the occupants. In Malaysia, cross laminated timber (CLT) is gaining favour in the building sector owing to the depletion resources of timbers. An 18 m2 cross laminated timber (CLT) structure were built at the Forest Research Institute Malaysia. However, there is lacking of information on the thermal comfort of CLT structure in Malaysia. Therefore, this study aimed t...

Eurocode 5—Future Developments towards a More Comprehensive Code on Timber Structures

Philipp Dietsch, Stefan Winter
The Eurocodes, including Eurocode 5, are of high technical quality. They include state of the art design methods which encompass expertise from all European countries. Feedback from practice nevertheless allows the conclusion that Eurocode 5 in the present form might not find a satisfactory acceptance in the timber construction community. There are indications that practice deems EN 1 995-1-1 too complicated and time intensive for standard timber constructions and partly incomplete when designin...

Mechanical Characterization and Hysteretic Behaviour of CLT Panels Made of Chilean Radiata Pine

E. Pérez, P. González, E. Saavedra, S. Tapia, J. Torelli, S. Orellana
The use of cross-laminated timber (CLT or XLAM) in the multi-storey buildings construction sector has been spreading in Europe and North America over the last twenty years. Considering that Chile has one of the largest radiata pine forest resources of the world, it is clearly possible to introduce this timber construction system in Chile. Therefore the mechanical characterization and seismic behaviour of 3-ply cross-laminated timber panels made of Chilean radiata pine were studied. The panels (2...

Iztok Sustersic, Massimo Fragiacomo, Bruno Dujic
AbstractThis paper investigates the seismic analysis of multistory cross-laminated timber (XLAM) buildings. The influence of different parameters such as wall geometry, vertical load level, friction, and, most importantly, connection stiffness, strength, and ductility is assessed. Linear and nonlinear finite-element (FE) analyses are carried out on a hypothetical 4-story case study building. The actual load-carrying capacity of the case study building is calculated with the nonlinear static push...

Development of Rotational Fixity Factors for Vibration Design of Cross-Laminated Timber Floors
https://www.semanticscholar.org/paper/Development-... [Vibration/Acoustic Performance] [Journal Article] 2018
Sigong Zhang, Jianhui Zhou, Jan Niederwestberg, Ying Hei Chui
As an emerging building solution, cross-laminated timber (CLT) floors have been increasingly used in mass timber construction. The current vibration design of CLT floors is conservative due to the assumption of simple support conditions in the floor-to-wall connections. It is noted that end fixity occurs as a result of clamping action at the ends, arising from the gravity load applied by the structure above the floor and by the mechanical fasteners. In this paper, the semi-rigid floor-to-wall co...
