Predicting the fire resistance of timber members loaded in tension
https://www.researchgate.net/publication/263109471... [Fire Performance] [Journal Article] 2013
Massimo Fragiacomo, Agnese Menis, Peter J. Moss, Isaia Clemente, Andrew H. Buchanan, Barbara De Nicolo
The paper presents a numerical model for predicting the fire resistance of timber members. Fire resistance is evaluated in a two‐step process implemented in the Abaqus finite element code: first, a time‐dependent thermal analysis of the member exposed to fire and then a structural analysis under a constant load are performed. The structural analysis considers the reduction in mechanical properties (modulus of elasticity and strength) of timber with temperature. The analysis terminates when the m...

Outlook for Cross-Laminated Timber in the United States
http://ojs.cnr.ncsu.edu/index.php/BioRes/article/v... [Markets] [Journal Article] 2014
Maria Fernanda Laguarda Mallo, Omar Alejandro Espinoza
Cross-laminated timber (CLT) is a building system based on the use of massive, multi-layered solid wood panels. Although CLT as a construction system has been successful in Europe, only a handful of CLT projects have been built in the U.S. This manuscript presents the results from qualitative research, carried out with the objective of assessing the market potential and barriers to the adoption of CLT in the U.S. Insights from national and international experts were collected using semi-structur...

Cross-laminated Timber: New projects show how the material is fulfilling "tall" orders
https://www.constructionspecifier.com/cross-lamina... [Tall Buildings] [Magazine/Newspaper Article] 2017
Kenneth E. Bland
Mass timber solutions incorporating CLT have the potential to revolutionize the built environment and address major challenges related to climate change, rapid urbanization, and the need for sustainable development. However, current building codes only allow combustible construction to be used in a range of low- to mid-rise residential and non-residential buildings up to six stories tall, based on the use of the building. The International Code Council’s (ICC’s) Tall Wood Building Ad-hoc Committ...

Timber-concrete-composites increasing the use of timber in construction
https://link.springer.com/article/10.1007%2Fs00107... [Alternative/Hybrid Configurations] [Journal Article] 2015
A. Dias, J. Skinner, K. Crews, T. Tannert
Timber-concrete-composite (TCC) systems have increasingly been used in recent decades. One of the main reasons for this development is related to applications that could not be built with timber alone, but that become possible with a TCC solution. This paper first gives a short overview of the use of TCCs, the relevant regulatory framework, and then presents several case studies of TCC applications. The perspectives and examples are from Europe, North America and Oceania to give a worldwide pers...

Mass timber is having its Maison Dom-Ino moment. At the 2014 Venice Architecture Biennale, a curious structure sat on the grass near the international pavilion in the Giardini. It was an engineered timber version of Le Corbusier’s Maison Dom-Ino, the seminal, prototypical reinforced concrete project, which was celebrating its 100th birthday....

Engineered Timber Structural Systems for Seismically Resilient Tall Buildings

Forest Products Laboratory
The wood building design community is developing technologies to enable economically competitive and high-performance urban infill buildings in seismic regions of the United States. Modern urbanization in the United States is driving a growing need for 8- to 14-story buildings for both residential and light commercial applications. For the wood building community, a viable tall building solution is the use of cross-laminated timber (CLT). Tall wood buildings are already constructed in low seismi...

Seismic design of floor–wall joints of multi-storey CLT buildings to comply with regularity in elevation
https://link.springer.com/article/10.1007%2Fs10518... [Seismic Performance] [Journal Article] 2018
Davide Trutalli, Luca Pozza
The effects of irregularity in elevation of cross-laminated timber buildings have not been fully analysed in literature to provide useful information for the design. In this work, a number of building configurations, regular or irregular in elevation, characterized by a different arrangement per storey of the floor–wall joints have been analysed by means of non-linear dynamic analyses. Comparative results in terms of ratio between the behaviour q-factor of the investigated irregular configuratio...

Overstrength of dowelled CLT connections under monotonic and cyclic loading
https://link.springer.com/article/10.1007%2Fs10518... [Connectors] [Journal Article] 2017
Lisa-Mareike Ottenhaus, Minghao Li, Tobias Smith, Pierre Quenneville
This paper presents an evaluation of overstrength based on an experimental study on dowelled connections in Cross Laminated Timber (CLT). Connection overstrength needs to be well understood in order to ensure that ductile system behaviour and energy dissipation can be achieved under seismic loading. Overstrength is defined as the difference between the code-based strength, using characteristic material strengths, and the 95th percentile of the true strength distribution. Many aspects contribute ...

Seismic Analysis of Cross-Laminated Multistory Timber Buildings Using Code-Prescribed Methods: Influence of Panel Size, Connection Ductility, and Schematization
https://onlinelibrary.wiley.com/resolve/reference/... [Seismic Performance] [Journal Article] 2016
Iztok Sustersic, Massimo Fragiacomo, Bruno Dujic
This 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 pushover met...
