Anne Gunnarshaug Lien, Nicola Lolli
The objective of this paper is to report and analyse strategies for cost reduction, design processes, and procurement models of one wooden nearly Zero Energy Building (nZEB) in Norway. The building investigated in this paper is the Moholt Allmenning, a newly-built student accommodation located in Moholt, Trondheim. Interviews with the buildings owner and the contractor were carried out to obtain information on the decision-making process during the procurement phase, the planning phase, and the ...

Joints with Dowel Type Fasteners in CLT Structures
https://www.semanticscholar.org/paper/Joints-with-... [Connectors] [Journal Article] 2013
Thomas Uibel, Hans Joachim Blass
The load carrying capacity of joints with dowel type fasteners in cross laminated timber (CLT) was the focus of a research project [1], [2], [3] conducted by the authors at Karlsruhe Institute of Technology (KIT). To examine the influence of load duration and climate variation on the load carrying capacity, these studies were complemented by long-term tests with screws in CLT, started in 2007 and finished at the end of 2012. ...

Tall Wood Buildings in the 2021 IBC Up to 18 Stories of Mass Timber
https://www.awc.org/pdf/education/des/AWC-DES607A-... [Tall Buildings] [Report] 2019
Scott Breneman, Matt Timmers, Dennis Richardson
In January 2019, the International Code Council (ICC) approved a set of proposals to allow tall wood buildings as part of the 2021 International Building Code (IBC). Based on these proposals, the 2021 IBC will include three new construction types—Type IV-A, IV-B and IV-C—allowing the use of mass timber or noncombustible materials. These new types are based on the previous Heavy Timber construction type (renamed Type IV-HT) but with additional fire-resistance ratings and levels of required noncom...

Seismic protection technologies for timber structures: a review
https://dx.doi.org/10.1007/s00107-019-01389-9... [Seismic Performance] [Journal Article] 2019
David Ugalde, José Luis Almazán, Hernán Santa María, Pablo Guindos
Timber structures traditionally provided satisfactory seismic performance due to multiple known features. However, the consequences of the last major earthquakes have clearly proofed that seismic timber design must further improve. In addition, nowadays timber structures target taller heights and so they face much larger seismic demands. All this together has made seismic protection technologies (SPTs) to emerge as a hotspot in timber engineering research, devoting more than 80 publications only...

Resistance of Cross-Laminated Timber Shear Walls for Platform-Type Construction
https://ascelibrary.org/doi/full/10.1061/%28ASCE%2... [Seismic Performance] [Journal Article] 2019
Md Shahnewaz, Marjan Popovski, Thomas Tannert
Cross-laminated timber (CLT) is gaining popularity in residential and nonresidential applications in the European and North American construction markets. For the adequate design of CLT shear walls, quantification of their lateral resistance is of paramount importance. In this paper, investigations with respect to the resistance of CLT shear walls for platform-type buildings under lateral loading are presented. Based on the possible kinematic motions of CLT shear walls under lateral loading (roc...

Today, the construction industry contributes to 40% of the world’s energy consumption and greenhouse gasemissions (GHGs). According to the Intergovernmental Panel on Climate Change’s(IPCC)report, the greenhouse gas emissions must be reduced by 40-50 percent to limit Global Warming to 1.5 degrees rather than 2 degrees by 2030. The United nation’s (UN) Sustainability Goals are the world's common work plan to stop climate change by 2030. To achieve the above goals, it is crucial for the constructio...

Structural behaviour of cross-laminated timber panels by the state space approach
https://www.witpress.com/elibrary/cmem-volumes/5/6... [Raw Materials] [Journal Article] 2017
Asad Shukri Albostami, Zhangjian Wu, Lee Cunningham
Over the last few years, Cross-Laminated Timber (CLT) panels have become increasingly popular in many structural applications. The growth in CLT uptake by the construction sector is likely to continue in line with the pressing need for sustainable construction. Although current design methods exist for CLT, often these have limits of applicability. In order to gain upmost efficiency, there is a need for improved analytical methods to fully determine the structural behaviour of CLT. In this artic...

World's first mass plywood panel approved for 18-story buildings

Drew Zeiba
Located in Lyons, Oregon, Freres Lumber has been in business for nearly a century. After starting out producing standard lumber projects, the company moved into wood veneers some 60 years ago and in 1998 purchased a plywood plant. Now, it’s made another step: getting U.S. and Canadian patents on its mass plywood panel (MPP), the first veneer-based mass timber panel in the world, and fire approvals to build up to 18 stories high with the panel....

Embedment Strength of Cross-Laminated Timber for Smooth Dowel-type Fasteners
https://www.researchgate.net/publication/331713974... [Connectors] [Conference Paper] 2018
Weiqun Dong, Qiao Li, Hao Zhang, Zhiqiang Wang, Jianhui Zhou, Meng Gong
Embedment strength is a significant property in the dowel type connection in timber structure, i.e. cross-laminated timber (CLT). The CLT design properties are different from those of sawn timber (ST) and glued-laminated timber (GLT) because of the orthogonal structure, which may particularly have influence on the design of connections. The layup feature, i.e. the thickness ratio of transverse layer (TRTL) was considered as an effective factor on CLT embedment strength in this study, except for ...

The Shear Plate Dowel Joint - Research on a novel connection for heavy timber structures
http://www.byggmek.lth.se/fileadmin/byggnadsmekani... [Connectors] [Thesis/Dissertation] 2019
Gustaf Larsson
An increased use of wood can reduce the environmental footprint of the building sector. In order to improve the competitiveness of heavy timber structures, the thesis presents a novel type of timber connection with a high degree of prefabrication. The connection includes a resilient bond line, meaning an elastic bond line with low stiffness yet high fracture energy. It has previously been shown that a large glued joint with a conventional stiff adhesive bond line acting in shear can be made stro...

Experimental and numerical analysis on fire behaviour of loaded cross-laminated timber panels
https://journals.sagepub.com/doi/10.1177/136943321... [Fire Performance] [Journal Article] 2019
Yuexiang Wang, Jin Zhang, Fang Mei, Jianan Liao, Weibin Li
Cross-laminated timber is a relatively new engineered timber material that can be used in the design and construction of modern timber buildings. A key factor that raises concerns in the wide application of cross-laminated timber is the uncertainty of its fire performance. This article describes experimental and numerical investigations on the fire behaviour of loaded cross-laminated timber panels manufactured with Canadian hemlock. A total of 10 cross-laminated timber panels with different numb...

Tamara S.F.A. França, Elizabeth Stokes, Juliet D Tang
Cross laminated timber (CLT) is a relatively recent addition to the North American timber construction market. CLT has been successfully used for construction in Europe and, in the past few years, manufacturers have looked forward to expanding the use of this product into the North American market. However, no termite susceptibility experiments have been published for the product and no standards exist for testing of the CLT and other mass timber products against termites. It is extremely import...
