Creep and duration of load characteristics of cross laminated timber (CLT) were evaluated from the test results of creep and duration of tests. Japanese Ceder (Cryptomeria japonica) was chosen for the specie for the laminations of the test specimens and API was chosen for the adhesive. The results are summarized as follows: (1) The creep factor [i.e. (Initial deflection + Creep deflection) / Initial deflection] for CLT was evaluated to be 2.0 and was almost equivalent to the creep factor commonl...

The in-plane shear specimens of full scale CLT panels are tested. From the test results, about the failure behaviour, if there is finger joint near the shear plane, cracks are tended to progress along the joint was confirmed. About the maximum shear unit stress was about 3N/mm 2 , and shear stiffness was about 600GPa calculated as the total cross section effective....

Rocking of narrow wall panels/columns causes embedding forces on the floor panels during earthquakes. In plain/out of plain compression tests and out of plain embedding tests of CLT panels were conducted. Compression and embedding strengths of in plain/out of plain strengths of Sugi CLT panels were obtained. These strengths of CLT panels with /without edge-glues were compared. Out of plain embedding strength loaded at the corner of CLT panels was fairly less than the normal embedding strength, a...

Mechanical Behaviour of Dovetail Connections for Cross Laminated Timber Wall Elements

Georg Stecher, Josef Kögl, Wilfried Beikircher
The goal of this study is to determine the shear and tension resistance capacity of a tenon connector made out of beech plywood for the connection of cross laminated timber wall elements. To determine the tensile and shear capacity of the connector according to EN 26 891 [1], tensile and shear tests were performed on cross laminated timber elements with thicknesses of 100 mm, 150mm and 180 mm which were connected with the pin connector. The sample set consisted of 36 test specimens of which were...

Adhesive Performance at Elevated Temperatures for Engineered Wood Products
https://www.apawood.org:443/Data/Sites/1/documents... [Fire Performance] [Report] 2005
Borjen Yeh, B. Herzog, T.G. Williamson
Engineered wood products, such as I-joists and laminated veneer lumber (LVL), have traditionally been manufactured with phenolic-based adhesives in North America. In the last few years, however, an unprecedented number of non-phenolic-based adhesive systems, such as polyurethane-based and isocynate-based adhesives, have been introduced to the engineered wood products industry. While these relatively new adhesives have demonstrated their compliance with most international adhesive standards, conc...

Even if there are no specific soundproofing requirements for individual rooms within an apartment, sound insulation should still be borne in mind when planning buildings to ensure privacy and provide protection against noise. In addition to ensuring an acoustically favourable layout of rooms in the building, it also makes sense to incorporate individual structural components with high-quality sound insulation between noisy and quiet areas or between rooms used for different purposes (e.g between...

Fire Resistance of Cross-Laminated Timber Panels Loaded Out of Plane

Massimo Fragiacomo, Agnes Menis, Isaia Clemente, Giovanna Bochiocchio
This paper describes bending tests at ambient temperature and large-scale fire tests of cross-laminated timber (Xlam) floor panels. Three specimens exposed to standard fire curve were loaded out-of-plane with different levels of uniformly distributed load, and in two cases collapse was reached. Other unloaded panels were protected using different cladding systems with the aim to investigate their thermal behavior. Experimental data obtained from the tests and discussed within the paper includes ...

Cross-laminated timber (CLT) is widely perceived as the most promising option for building high-rise wood structures due to its structural robustness and good fire resistance. While gravity load design of a tall CLT building is relatively easy to address because all CLT walls can be utilized as bearing walls, design for significant lateral loads (earthquake and wind) can be challenging due to the lack of ductility in current CLT construction methods that utilize wall panels with low aspect ratio...

Nail-lam floor and wall assemblies have been used for more than a century, particularly in warehouses where solid, sturdy floors were required. It is now being recognized again as a valid substitute for concrete slabs and steel decking in commercial and institutional buildings, and residential buildings in which it is often exposed to create a unique aesthetic. In addition to being used in floors, decks and roofs, mass timber panels are now often used for the timber elevator and stair shafts in...
