Potential impact of subterranean termites on cross-laminated timber (CLT) in the Southeastern U.S
https://research.fs.usda.gov/treesearch/56327... [Moisture/Durability] [Conference Paper] 2017
C. Elizabeth Stokes, Rubin Shmulsky, Juliet D. Tang
Cross-laminated timber (CLT) is an emerging product in the North American mass timber market. Intended to compete with pre-cast concrete panels for modular construction, these laminated wall and floor-sized panels have been successfully used in European construction markets for the past 20 years. However, introduction of this material to areas of North America that have high pressure from subterranean termite and decay fungi may prove detrimental to the potential market for this product. This pa...

Strength and deformation characteristics of typical X-lam connections
https://www.researchgate.net/publication/289242376... [Connectors] [Conference Paper] 2012
Igor Gavric, Massimo Fragiacomo, Ario Ceccotti
This paper presents some of the results of an extensive experimental programme on typical X-Lam connections, conducted at CNR-IVALSA research institute. The goal of this research is to provide a better understanding of the seismic performance of connections in cross-laminated timber buildings subjected to seismic actions. In-plane monotonic and cyclic shear tests were performed on mechanical screwed connections between adjacent parallel wall-wall and floor-floor X-Lam panels. In addition, monoto...

Cristiano Loss, Stefano Pacchioli, Andrea Polastri, Daniele Casagrande, Luca Pozza, Ian Smith
Changes to building codes that enable use of materials such as cross-laminated timber (CLT) in mid-and high-rise construction are facilitating sustainable urban development in various parts of the world. Keys to this are the transition to multi-performance-based design approaches along with fewer limitations on heights or the number of storeys in superstructures constructed from combustible materials. Architects and engineers have increased freedom to apply new design and construction concepts a...

Dynamic response of tall timber buildings

Dynamic response of tall timber buildings
The low carbon footprint and high structural efficiency of engineered wood materials make tall-timber buildings an attractive option for high-rise construction. However, due to the relatively low mass and stiffness characteristics of timber structures, some concerns have been raised regarding their dynamic response. This paper examines the dynamic behaviour of tall timber buildings under tornado and downburst wind loads. It summarizes the results of extensive response history analyses over a sui...

Numerical modelling of timber connections under fire loading using a component model
https://www.researchgate.net/publication/257230389... [Fire Performance] [Journal Article] 2009
Paulo Cachim, Jean-Marc Franssen
This paper describes a component model for dowelled timber connections under fire loading. The component model of the dowelled connection is first developed and calibrated for room temperature. The constitutive relations for dowel–timber interaction are detailed and compared with experimental results. In the fire situation, a two-step approach is used: first, three-dimensional (3D) thermal analysis of the connection is performed using a conductive model with timber properties defined in Eurocode...

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...

Tom Owens
In the past decade, these nations, and many others, have been host to some of the most destructive earthquakes in recent memory. Along with the inestimable human and emotional toll these events take on communities around the globe, the costs associated with reconstruction efforts are equally astronomical, often edging into the billions of dollars. Although we can’t effectively predict or stop earthquakes from occurring, we can be ready, and minimize the impacts of these damaging seismic events....

Fire-Exposed Cross-Laminated Timber - Modelling and Tests
https://www.researchgate.net/publication/326710882... [Fire Performance] [Conference Paper] 2010
Joachim Schmid, Jürgen König, Jochen Köhler
Cross-laminated timber (CLT) is increasingly used in medium-rise timber buildings, for the time being up to eight storeys, among other reasons for cost effectiveness and robustness. This paper presents a simple design model using the effective cross-section method for the structural fire design, i.e. the determination of the mechanical resistance with respect to bending (floors). Performing advanced calculations for a large number of lay-ups of various lamination thicknesses, using the thermal a...

Moment resisting dowelled joints in timber structures: Mechanical behaviour under cyclic tests
https://www.researchgate.net/publication/287247545... [Connectors] [Journal Article] 2013
Andrea Polastri, Roberto Tomasi, Maurizio Piazza, Ian Smith
This paper presents an experimental study aimed at collecting information on the response of knee connections to high amplitude fully-reversed rotational deformations, and compares the findings with seismic performance requirements in Eurocode 8. The connections investigated attached twinned outer glulam members to a single glulam member sandwiched between them using steel dowels. Attention is also directed at assessing whether the timber design provisions of Eurocode 5 can be used to estimate m...

A series of compartment fire experiments has been undertaken to evaluate the impact of combustible cross laminated timber linings on the compartment fire behaviour. Compartment heat release rates and temperatures are reported for three configuration of exposed timber surfaces. Auto-extinction of the compartment was observed in one case but this was not observed when the experiment was repeated under identical condition. This highlights the strong interaction between the exposed combustible mater...

Seismic protection technologies for timber structures: a review
https://link.springer.com/content/pdf/10.1007%2Fs0... [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 onl...
