Xiao Li, Xia Zhang, George Hadjisophocleous, Cameron McGregor
With the adoption of performance-based fire design and the development of new engineered wood products, wood-based mid-rise and high-rise buildings are beginning to be constructed all around the globe. This trend has accelerated efforts to gain more understanding of the risks associated with combustible construction. To compare the differences between combustible and non-combustible construction, a series of full scale fire tests was conducted at Carleton University, the results of which are pre...
Performance of cross-laminated timber shear walls for platform construction under lateral loading
https://pdfs.semanticscholar.org/aafc/27662342b01f... [Seismic Performance] [Thesis/Dissertation] 2013
Md Shahnewaz
Cross-laminated timber (CLT) is gaining popularity in residential and non-residential applications in the North American construction market. CLT is very effective in resisting lateral forces resulting from wind and seismic loads. This research investigated the in-plane performance of CLT shear wall for platform-type buildings under lateral loading. Analytical models were proposed to estimate the in-plane stiffness of CLT wall panels with openings based on experimental and numerical investigatio...

In-Plane Strength and Stiffness of Cross-Laminated Timber Shear Walls
https://pdfs.semanticscholar.org/40c3/4708b5a744e7... [Mechanical Performance] [Journal Article] 2018
Md Shahnewaz, Shahria Alam, Thomas Tannert
The research presented herein investigated the in-plane performance of cross-laminated timber (CLT) shear walls for platform-type buildings under lateral loading. Finite element models of CLT connections (i.e., brackets, hold-downs and self-tapping screws) were developed in OpenSees and calibrated against experimental tests to represent the connections hysteresis behaviour under cyclic tension and shear loading. The results were incorporated into models of CLT single and coupled shear walls. The...
Ductility Based Force Reduction Factors for Symmetrical Cross-Laminated Timber Structures
https://www.researchgate.net/publication/274959160... [Seismic Performance] [Conference Paper] 2015
Marjan Popovski, Shiling Pei, John W. van de Lindt, Erol Karacabeyli
European or North American building codes. One of the most important issues for designers of CLT structures in earthquake prone regions when equivalent static design procedure is used, are the values for the force modification factors (R-factors) for this structural system. Consequently, the objective of this study was to derive suitable ductility-based force modification factors (Rd-factors) for seismic design of CLT buildings for the National Building Code of Canada (NBCC). For that purpose, t...

(PDF) Measuring-up in timber: A critical perspective on mid- and high-rise timbe
https://www.researchgate.net/publication/281127405... [Markets] [Journal Article] 2014
Patrick Fleming, Simon Smith and Michael Ramage
Architects, engineers and researchers alike often cite practical reasons for building with wood. Since the development of curved glulam beams and columns over a century ago, the widespread use of massive structural timber elements has allowed architects and engineers to design and build in wood with unprecedented speed and scale. Moreover, rising concerns of climate change and the carbon-dioxide emissions associated with construction encourage the use of wood as a viable alternative to steel and...
Seismic protection technologies for timber structures: a review
https://link.springer.com/article/10.1007%2Fs00107... [Seismic Performance] [Journal Article] 2019
David Ugalde, José Luis Almazán, Hernán Santa María, Pablo Guindos
Although many distinct devices and techniques are intended to this end, SPTs applied to timber structures may be grouped into supplemental damping, seismic isolation, and rocking systems. An outlook for future research trends is expected towards cost-effectiveness, rate-effects, engagement of devices, and design guidelines which may expand these technologies bringing timber structures into higher levels of seismic performance. Besides single-family housing, current developments in construction ...
Experimental Investigation of the Bending Behaviour of Timber-to-Timber Composite-Section Beams
https://www.researchgate.net/publication/330347570... [Mechanical Performance] [Conference Paper] 2014
Osama Sam Salem
Wood has long been in demand as a competent building material due to its beauty, economy, and ease of construction. Excellent material properties are exhibited by a number of new engineered-wood products, such as glued-laminated (Glulam) and cross-laminated timbers (CLT). New experimental data on the structural behavior of CLT-to-Glulam composite-section beams is presented in this paper. Four full-scale simply-supported beams, each composed of two different engin...
Repair and Strengthening of Traditional Timber Roof and Floor Structures
https://link.springer.com/chapter/10.1007/978-981-... [Other] [Journal Article] 2017
Jorge M. Branco, Thierry Descamps, Eleftheria Tsakanika
In many countries, traditional buildings comprise timber roof and floor structures. Most of these structures are degraded from different causes and need to be repaired or strengthened to ensure current and/or to fulfil the requirements of a new use of the building. Current knowledge assumes the need to preserve and to protect existing timber structural systems as a cultural value, with important advantages to the overall behaviour of the building. This growing sensibility towards the preservatio...

Most building envelope / building enclosure failures can be traced back to water. If we can learn to manage (rather than control) water in the building envelope/enclosure, we will have learned how to master an essential component of building science. We have deliberately chosen the term “manage” since it implies using the laws of nature to our advantage rather than attempting to conquer nature by brute force. Attempts to control water movement by face sealing walls, for example, require perfect ...
Butt-joint bonding of timber as a key technology for point-supported, biaxial load bearing flat slabs made of cross-laminated timber
https://iopscience.iop.org/article/10.1088/1755-13... [Mechanical Performance] [Journal Article] 2019
S. Zoellig, M. Muster, A. Themess
An efficient butt-joint bonding technology allows to build new types of timber structures. Under the name Timber Structures 3.0 a connection has been developed which connects timber elements with an end-grain to end-grain butt joint bonding. Therefore, it is now possible to build continuous, point supported flat slabs in cross laminated timber (CLT). Multiple CLT slabs are connected rigidly together and are only supported by columns. Some major challenges had to be solved in terms of bending str...
Seismic analysis of multi-storey timber buildings braced with a CLT core and perimeter shear-walls
https://link.springer.com/article/10.1007/s10518-0... [Seismic Performance] [Journal Article] 2019
Andrea Polastri, Matteo Izzi, Luca Pozza, Cristiano Loss, Ian Smith
The seismic behaviour of multi-storey heavy-frame timber building superstructures braced by Cross-Laminated-Timber (CLT) shear-walls is investigated based on numerical linear dynamic simulations. All systems analysed have the same rectangular plan footprint dimensions, type of framework and shear-walls arrangement at each storey. For structural efficiency, the layout of lateral load-resisting systems combines a central building core with partial length perimeter shear-walls. What differs between...
Sound radiation of cross-laminated timber panels based on a higher order plate theory
https://www.sciencedirect.com/science/article/pii/... [Vibration/Acoustic Performance] [Journal Article] 2019
Thomas Furtmüller, Christoph Adam
In this contribution, the problem of sound radiation by a rectangular baffled cross-laminated timber (CLT) plate excited by a point force is addressed. Due to the inherent properties of CLT, a higher order shear deformable plate theory is needed to capture its deformation field. To this end, a recently proposed equivalent single layer plate theory is extended to incorporate dynamic effects. The derived plate model is applied to flexural wave propagation in infinitely extended plates, revealing c...

The elastic and ductile behaviour of CLT wall-floor connections and the influence of fastener length
https://www.researchgate.net/publication/332094285... [Connectors] [Journal Article] 2019
Conan O'Ceallaigh, A.M. Harte
An investigation was carried out to examine the influence of the fastener length on the elastic and ductile failure behaviour of typical steel-to-timber bracket connections in Cross Laminated Timber (CLT) manufactured from C16 spruce. The behaviour of single screw-type fasteners within CLT of length 25 mm, 50 mm and 75 mm are examined under tension and shear loading. Multiple screw-type fasteners have been utilised to examine monotonic and cyclic behaviour of steel bracket-fastened CLT connectio...
