The feasibility of manufacturing cross-laminated timber (CLT) using fast-grown small diameter Eucalyptus timber was explored in preliminary studies. However, eucalyptus bonded with commercial one-component polyurethane adhesive usually provides poor resistance to delamination and shear force. The effects of priming surface of eucalyptus CLT lamella intended for a bondline and different adhesives on block shear strength (BSS), wood failure percentage (WFP), and rate of delamination (RD) of Eucaly...

Johannes Schneider, Siegfried F. Stiemer, Solomon Tesfamariam, Erol Karacabeyli, Marjan Popovski
Wood-frame is the most common construction type for residential buildings in North America. However, there is a limit to the height of the building using a traditional wood-frame structure. Cross-laminated timber (CLT) provides possible solutions to mid-rise and high-rise wood buildings. CLT offers many advantages such as improved dimensional stability, a quicker erection time and good performance in case of fire. In order to introduce the cross-laminated timber products to the North American ma...

When designing restaurants, stores, and low-rise offices, certain features come to mind as typical. These buildings tend to have large openings that allow plenty of daylight. Many have high ceilings and (by extension) tall walls, open floor plans, and the ability to reconfigure the interior as tenant needs change....

Pres-Lam in the US: the seismic design of the Peavy Building at Oregon State University
http://db.nzsee.org.nz/2017/O5C.1_Sarti.pdf... [Seismic Performance] [Conference Paper] 2017
F. Sarti, T. Smith, I. Danzig, E. Karsh
Pres-Lam is a post-tensioned rocking timber technology that has been developed over the last decade at the University of Canterbury. Pres-Lam overcomes a major challenge in timber construction, the development of a high strength moment connection, by tying mass timber elements together with high-strength steel post-tensioned tendons. In seismic areas, additional reinforcing can be added to the system increasing capacity as well as providing hysteretic damping. In 2010 Pres-Lam moved from laborat...

Seismic resilient structures with Cross Laminated Timber (CLT) walls coupled with innovative Resilient Slip Friction (RSF) joints
http://db.nzsee.org.nz/2017/O5C.5_Hashemi.pdf... [Seismic Performance] [Conference Paper] 2017
A. Hashemi, P. Quenneville, P. Zarnani
There is an increasing public pressure to have damage avoidant structural systems in order to minimize the destruction after severe earthquakes with no post-event maintenance. This study presents and investigates a hybrid steel-timber damage avoidant Lateral Load Resisting System (LLRS) using Cross Laminated Timber (CLT) walls coupled with innovative Resilient Slip Friction (RSF) joints and boundary steel columns. RSF joints are used as ductile links between the adjacent walls or between the wal...

Experimental campaign of mechanical CLT connections subjected to a combination of shear and tension forces: Beyond their Limits
https://www.researchgate.net/publication/305872565... [Connectors] [Book/Book Section] 2016
Luca Pozza, Milena Massari, Marco Savoia, Barbara Ferracuti
Cross-Laminated Timber (CLT) structures dissipate energy during earthquake only in mechanical connections, which are located in few specific zones. The full definition of their structural behaviour and their correct design is then of crucial importance, especially in seismic conditions. Many studies were carried out on this topic during the last decade in Europe, North America and Japan in order to define monotonic and cyclic behaviour of mostly used connections when only one action (i.e. tensio...

Developing a prefabricated low-carbon construction system using cross-laminated
https://www.researchgate.net/publication/275939571... [Environmental Performance] [Journal Article] 2012
Steffen Lehmann
Prefabricated engineered solid wood panel construction systems can sequester and store CO2. Modular cross-laminated timber (CLT, also called cross-lam) panels form the basis of low-carbon, engineered construction systems using solid wood panels that can be used to build residential infill developments of 10 storeys or higher. Multi-apartment buildings of 4 to 10 storeys constructed entirely in timber, such as recently in Europe, are innovative, but their social and cultural acceptance in Austral...

Thanks to a two-year, $250,000 Wood Innovations Grant from the United States Forest Service, and with further support from the National Hardwood Lumber Association, Indiana Hardwood Lumberman’s Association, and the Indiana Department of Natural Resources, IKD is currently working on an advancement that may completely change the cross-laminated timber (CLT) market. Currently, CLT is made primarily of softwoods, which have the advantage of being fast growing and inexpensive. IKD believes the futur...

Continuity connection for cross laminated timber (CLT) floor diaphragms

Masoud Sadeghi Sheikhtabaghi
Cross Laminated Timber (CLT) is a lightweight construction material with a strength and stiffness comparable to Reinforced Concrete (RC). A crucial aspect of fully realizing the potential of CLT as a structural material is ability to interconnect it to similar and dissimilar materials. A study of connections was made through in-plane shear and tension tests on half-lapped and single-spline connections that make edge-to-edge jointing between CLT panels using screws. A novel aspect of the study is...

Development of evaluation methodology for rolling shear properties in cross-laminated timber (CLT)
https://unbscholar.lib.unb.ca/islandora/object/unb... [Mechanical Performance] [Thesis/Dissertation] 2013
Qinyi Zhou
The rolling shear modulus is very low, leading to rolling shear failure in the cross layer of cross-laminated timber (CLT). The overall objective of this thesis work was to develop an appropriate methodology for measuring the rolling shear properties of CL T. This research consists of three article format chapters, which were aimed at: 1) obtaining a better understanding of advantages and disadvantages of using the bending test and twoplate shear test for determining the rolling shear properties...

Moisture content and joint behavior of bridge decks made of mechanically laminated timber
https://unbscholar.lib.unb.ca/islandora/object/unb... [Moisture/Durability] [Thesis/Dissertation] 2018
Wanrong Zhu
Bridges with timber decks are widely used for low-traffic volume areas in New Brunswick, Canada, because of multiple advantages over conventional cast-in-place concrete decks. However, the NLT decks in New Brunswick are required to be replaced every 10-15 years, which is a very costly exercise. This calls for a new type of timber bridge deck system with a service life of more than 15 years. The overall objective of this study was to understand the change in moisture content (MC) of local bridge ...

Cristiano Loss, Afrin Hossain, Thomas Tannert
This paper presents an experimental study to evaluate the use of spatially arranged self-tapping screws (STS) as shear connections for cross-laminated timber panels. Specifically, simple butt joints combined with crossed STS with different inclinations were investigated under quasi-static monotonic and reversed-cyclic loadings. The influence of the number and angle of insertion of screws, screws characteristics, friction and loading on the joint performance was explored. The yield load, load-car...

Capacity design of traditional and innovative ductile connections for earthquake-resistant CLT structures
https://link.springer.com/content/pdf/10.1007%2Fs1... [Connectors] [Journal Article] 2018
Davide Trutalli, Luca Marchi, Roberto Scotta, Luca Pozza
Traditional connections in earthquake-resistant cross-laminated timber buildings are susceptible of brittle failures, even when buildings are designed and supposed to be ductile. This is mainly due to the large underestimation of the actual strength of the ductile components, with consequent increased strength demand for the brittle parts, which may fail if designed with insufficient overstrength. Recent studies demonstrate that the use of steel connections characterized by a well-defined mechan...

This paper investigates the structural behaviour of a twelve-storey Cross-Laminated Timber (CLT) building subjected to sudden removal of internal and external ground floor loadbearing walls, and computes the probability of disproportionate collapse. Analyses are carried out at three different structural idealisations, accounting for feasibility and complexity of finite elements models to understand their performance at: (i) the global, (ii) the component and (iii) the connection level. Focus is ...
