Cross-laminated timber is environmentally friendly material which possess a decreased level of anisotropy in comparison with the solid and glued timber. Cross-laminated timber could be used for load-bearing walls and plates of multi-storey timber buildings as well as decking structure of pedestrian and road bridges. Design methods of cross-laminated timber elements subjected to bending and compression with the bending were considered. The presented methods were experimentally validated and verif...

Cross Laminated Timber (CLT) is a structural plate element which is approved in Europe and is intended to be approved in Japan. It consists of small dimension laminae, in which laminae parallel and perpendicular to longitudinal direction are interlaminated. We performed tensile tests for the drift pin joint with steel insert plate. Specimen consisted of CLT was made from Japanese cedar laminae (thickness of laminae t = 30mm, five laminae were layered), with steel drift pin plate. Odd-numbered la...

Cross-laminated timber elements are used as load-bearing components. These are elements that are made of boards sorted according to strength, having widths ranging between 80 and 240 mm. Board thicknesses are between 19 and 45 mm. The wood species used are mainly common spruce or fir, but also pine and larch. Typically, individual plies - usually 3, 5 or 7 plies - are extensively glued together while alternatively turning them by 90°, using adhesives that are admitted for load-bearing purpose...

Cross-laminated Timber (CLT) has been extensively used in Europe and is now gaining momentum in North America; both Canada and more recently the U.S. Construction projects have shown that CLT can effectively be used as an alternative construction material in mid-rise structures and has significant potential in commercial and industrial buildings. In the United States, the CLT system is not currently recognized in seismic design codes and therefore a seismic design can only be performed through a...

Anthonie Kramer,
The development of cross-laminated timber (CLT) panel technology has opened up new opportunities for wood in tall buildings. Several characteristics including seismic performance and speed of construction have raised interest among designers. As CLT gains acceptance in the industry, alternative structural solutions need to be investigated to improve performance of CLT as a building material. The first study presented is an assessment of the viability of hybrid poplar for use in CLT panels. Hybr...

[Abstract]: Cross Laminated Timber (CLT) is made from dimensional lumber, laminated in layers with the grain in each layer placed orthogonal to the layer before it. CLT is made from timber, which is an environmentally attractive option in comparison to the reinforced concrete or steel structures which dominate the multistorey building market sector. Timber is one of the very few sustainable carbon neutral building materials available. New technology such as advanced Building Information Modelin...

Cross laminated timber (CLT) is a new type of timber structural system that has just been introduced in North America, but has been used successfully in Europe for over 20 years. There have not been any notable data sets developed on the performance of tall CLT buildings during major earthquakes and there are no seismic design criteria currently in place for CLT structures. Shake table testing of walls, assemblies and multi-storey CLT structures have been performed, but dedicated nonlinear numer...
