Bending properties of cross laminated timber (CLT) with a 45° alternating layer configuration
https://bioresources.cnr.ncsu.edu//BioRes_11/BioRe... [Mechanical Performance] [Journal Article] 2016
Buck, D., Wang, X., Hagman, O., and Gustafsson, A.
Bending tests were conducted with cross laminated timber (CLT) panels made using an alternating layer arrangement. Boards of Norway spruce were used to manufacture five-layer panels on an industrial CLT production line. In total, 20 samples were tested, consisting of two CLT configurations with 10 samples of each type: transverse layers at 45° and the conventional 90° arrangement. Sample dimensions were 95 mm × 590 mm × 2000 mm. The CLT panels were tested by four point bending in the main load-c...

Joining of wood layersComparison of different assembling techniques regarding cost, durability, and ecology – A survey of multi-layer wooden panel assembly load-bearing construction elements
https://bioresources.cnr.ncsu.edu//BioRes_10/BioRe... [Economics/Costs] [Journal Article] 2015
Buck, D., Wang, X., Hagman, O., and Gustafsson, A.
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...

Cyclic response of insulated steel angle brackets used for cross-laminated timber connections
https://www.researchgate.net/publication/348372130... [Connectors] [Journal Article] 2021
Meta Kržan, Boris Azinović
d over the flanking parts, special insulation layers are used between the CLT walls and slabs, together with insulated angle-bracket connections. However , the influence of such CLT connections and insulation layers on the seismic resistance of CLT structures has not yet been studied. In this paper, experimental investigation on CLT panels installed on insulation bedding and fastened to the CLT floor using an innovative, insulated, steel angle bracket, are presented. The novelty of the investiga...

Innovative Approach in Acoustic Simulation of Timber Walls
https://www.researchgate.net/publication/336150038... [Vibration/Acoustic Performance] [Conference Paper] 2019
Caniato, Marco & Bonfiglio, Paolo & Bettarello, Federica & Gasparella, Andrea
The acoustic insulation performance of a glulam system (timber-framed wall) is of paramount importance in sustainable lightweight constructions. Nevertheless, traditional models like impedance coupling or double-leaf theory cannot offer robust results comparable to measurements. Even Finite Element (FE) simulations may not provide good results, due to high variables computations models and the resultant error propagation. For these reasons, in this paper the Transfer Matrix Modelling (TMM) metho...

Laboratory experiments on hygrothermal behaviour of real-scale timber walls

Helisoa Rafidiarison, Eric Mougel, Alexis Nicolas
Hygrothermal performance of massive wood and wooden materials used as structural purposes in building envelope are measured by means of laboratory tests. For this purpose, hygrothermal short-time behaviour of two massive timber walls exposed to summer climatic conditions were investigated. A double climatic chamber simulating real on-site conditions was designed and built at the LERMAB/ENSTIB site in Epinal and used during wall behaviour assessment. Temperature and humidity variations with time ...

Tupenaite, Laura & Žilėnaitė, Viktorija & Kanapeckiene, Loreta & Sajjadian, Seyed & Gečys, Tomas & Sakalauskienė, Lina & Naimaviciene, Jurga
Although the majority of high-rise buildings are constructed from concrete and steel, there is a growing interest in the new generation of multi-storey timber buildings around the world and several ecologically sustainable structural systems have already been proposed. This research aims to review and compare the highest contemporary timber buildings in terms of economic and environmental efficiency. For this purpose, the Simple Additive Weighting (SAW) method is used. Five high-rise timber buil...

https://link.springer.com/article/10.1007/s00107-0... [Raw Materials] [Journal Article] 2016
Yeonjung Han, Jun-Ho Park, Yoon-Seong Chang, Yonggun Park, Jung-Kwon Oh, Jung-Pyo Hong, Jun-Jae Lee & Hwanmyeong Yeo
The objective of this study was to evaluate the effect of lamina distortion control on the production yield of cross-laminated timber (CLT) using domestic larch (Larix kaempferi) wood. The measured production yield of CLT was 27 %. The yields based on log volume of sawing, planing, cross-cutting, and finish planing of CLT were 49, 66, 96, and 86 %, respectively. The yield of sawing and planing can be improved by controlling distortion during drying. Using an experimental enforced-loading apparat...

With the increased usage of Cross Laminated Timber (CLT) in the United States, research efforts have been focused on demonstrating CLT as an effective Seismic Force Resisting System (SFRS). Presented in this paper are the findings of full-scale shake table tests of a two-story 223 m 2 (2400 ft 2) building with two sets of CLT shear walls on the first and second story. The testing consisted of three phases, each with a unique wall configuration, but only the first phase is presented herein, which...

Wood as an Exposed Building Material for Indoor Climate Adaptation
https://idp.springer.com/authorize?response_type=c... [Environmental Performance] [Book/Book Section] 2018
Kristine Nore, Dimitrios Kraniotis, May-Linn Sortland
Use of massive wood has increased during the last decade. The concept of massive wood, mainly as cross laminated timber elements (CLT), has become a popular building method for new constructions, both in public and private sector. Massive wood elements take advantage of wood as building material, also as an indoor climate buffer. Moholt 50|50 is a new student-housing project in Trondheim, Norway, which consists of five mass timber towers. Each of them with eight stories built in CLT on top of a ...
