Meng Gong, Y.H. Chui, Ling Li
Massive timber panels (MTPs) has shown a great potential in construction of tall buildings. Evaluation of the face-bond strength of MTPs is of an interest to use of this kind of products. This study was aimed at developing an appropriate test procedure for evaluating the adhesive bond strength of cross-laminated laminated strand lumber (LSL). Short span bending tests were conducted on two-layer asymmetric cross-laminated LSL specimens, which were adhesively bonded using two-component polyurethan...

Tall timber buildings: Applications of solid timber construction in multi-storey buildings
http://global.ctbuh.org/resources/papers/download/... [Tall Buildings] [Journal Article] 2011
M. Wells
Timber construction offers the possibility of minimal cost and no carbon footprint combined. Cross-wall high-rise structures - residential buildings in particular - have relatively low stresses in their structural components. Walls and floors that are dimensioned to provide adequate acoustic separation and thermal performance have plenty of substance to resist the levels of applied loading encountered. This paper describes the design of construction of a nine story cross-laminated timber apartme...

Self-extinguishment of cross-Laminated timber
http://repository.tudelft.nl/view/ir/uuid:c7e7ade5... [Fire Performance] [Thesis/Dissertation] 2015
R. Crielaard
Cross-laminated timber, or CLT, is currently receiving attention for its potential use in tall building structures. Timber being a combustible material, one of the main challenges for the construction of these buildings is the potential fire risk that results from its use in the structure. For tall buildings, there is an increased severity of the consequences of structural failure as result of a fire. In order to obtain the desired level of safety, building codes typically require tall buildings...

Hysteresis behavior of bracket connection in cross-laminated-timber shear walls

Yin-Lan Shen, Johannes Schneider, Solomon Tesfamariam, Siegfried F. Stiemer, Zai-Gen Mu
Cross Laminated Timber (CLT), a new generation of engineered wood-based products, provides promising solutions to the mid- and high-rise wood building. A series of connection tests and CLT shear walls tests subjected to general quasi-static monotonic and cyclic loading protocols have been undertaken at FPInnovations of Canada to gain comprehensive understanding of its structural properties. Using these testing results, two hysteretic models (Saws model and Pinching4 model) in OpenSees are calibr...

Timber and wood-based engineered products are becoming very important as structural materials, especially in the drive towards sustainable technologies and construction. For structural wooden products, it is very important to improve their properties to be more competitive and reliable as a sustainable low-carbon material and a major contributor to affordable buildings. This applies particularly to larger, more complicated structures where timber is becoming a realistic alternative....

Hybrid Beech and Spruce Cross-Laminated Timber
https://www.researchgate.net/publication/307629972... [Raw Materials] [Conference Paper] 2016
Simon Aicher, Maren Hirsch, Zachary Christian
A hybrid, three-layered, softwood-hardwood cross-laminated timber build-up with outer layers of European spruce (Picea abies) and a center cross-layer of European beech (Fagus sylvatica) has been investigated with regard to out-of-plane bending. The determination of the rolling shear properties of the beech cross-layer performed by different test and measurement methods comprising bending and compression shear tests was of primary interest. The shear capacity of the composite is significantly in...

A project contribution to the development of sustainable multi-storey timber buildings

Catarina V. Silva, Jorge M. Branco, Paulo B. Lourenço
Wood is a natural material, renewable, easily recyclable, and able to store carbondioxide, which makes tall timber buildings a solution with potential to answer the main sustainability targets. Cross laminated timber (CLT) has been pointed out as the best wood-based material to make this ambition a real thing. In order to understand why, this paper introduces the material and describe some demonstration buildings recently built. Based on diagnosed weaknesses of CLT buildings, it is presented an ...

Experimental Investigation of Tensile Strength and Stiffness Indicators Regarding European Beech Timber
https://www.researchgate.net/publication/306915201... [Raw Materials] [Conference Paper] 2016
Thomas Ehrhart, Gerhard Fink, René Steiger, Andrea Frangi
In the present paper, several visual and physical strength and stiffness related indicators are investigated concerning their influence on the tensile strength and stiffness of European beech timber boards. Besides well-known visual characteristics, such as knots and bark inclusions, further ones are analysed. Destructive tensile tests on 150 timber boards were performed in order to determine the actual tensile strength and the static modulus of elasticity. By means of correlation analysis, the ...

Andreas Falk, Peter Von Buelow
This paper presents an explorative study on applications of cross-laminated timber (CLT) elements in shell structures. Previous studies of plate tensegrity, folded plate roofs interacting with stabilising steel-based systems and studies inspired by origami show a widening range of possibilities to develop timber-based shells. Steadily rising interest in rationality during pre-fabrication, transport and on-site construction in contemporary industrialised production increases the competitiveness o...

Dalston Works is the world’s largest CLT building, and a landmark project in our ambition to roll out the use of timber construction in high-density urban housing, across London and beyond. The ten-storey, 121-unit development is made entirely of CLT, from the external, party and core walls, through to the floors and stairs, weighing a fifth of a concrete building of this size, and reducing the number of deliveries during construction by 80 per cent....

A mathematical model for the sustainability of the use of cross-laminated timber in the construction industry: the case of Spain
https://link.springer.com/content/pdf/10.1007%2Fs1... [Raw Materials] [Journal Article] 2014
Mario Fernández, Arturo Martínez, Adolfo Alonso, Laura Lizondo
In recent years, computerized mathematical modelling has enabled construction-related problems to be resolved and predictions to be made regarding the behaviours of buildings and their environments in a more rigorous fashion than was the case with the deterministic models used until now. This model enables the analysis of a simulation of the sustainability of the use of timber as a major structural component in construction. Thus, using a unique model, which could be adapted to the particular ch...

Peggi Clouston, Sanjay Arwade, Alexander Schreyer
Cross laminated timber is a processed building material that is opening up new opportunities for wood in the construction industry. Made from lumber glued together in crosswise layers, the material is used in floor, roof, and wall assemblies in building construction. The product is an environmentally friendly alternative to steel and concrete. Its composite nature is forgiving of defects to an extent, making it a promising construction material of varied quality, small-diameter, and environmenta...
