In-plane Shear Modulus of Cross-laminated Timber by Diagonal Compression Test
https://www.semanticscholar.org/paper/In-plane-She... [Mechanical Performance] [Journal Article] 2019 Sven Berg, Jonas Turesson, Mats Ekevad, Anders Björnfot Cross-laminated timber (CLT) is an engineered wood material that is used in the construction industry, e.g., for floors, walls, and beams. In cases where CLT-elements are used as shear walls, the in-plane-stiffness is an important property. For non-edge glued CLT, in-plane shear stiffness is lower than for edge-glued CLT. To evaluate the non-edge glued CLT panel’s in-plane shear modulus, the diagonal compression test and finite element (FE) simulation was used. FE-models with both isotropic and ... |

Influence of interior layer properties to moisture dry-out of CLT walls
https://www.researchgate.net/publication/330976539... [Moisture/Durability] [Journal Article] 2019 Villu Kukk, Annegrete Külaots, Jaan Kers, Targo Kalamees The objective of this study was to determine the maximum allowable initial moisture content (MC) for cross-laminated timber (CLT) walls having both exterior and interior thermal insulation. A laboratory test was conducted, for which four test walls with two different insulation solutions and two different MCs were built. Based on the test results, a simulation model was configured and simulations using the model were completed. The simulation results determined that the maximum allowable initial... |

VaproShield Mass Timber Building Enclosure Design Guide
https://www.rdh.com/resource/vaproshield-mass-timb... [Design/Architectural aspects] [Others] 2019 Bailey Brown, Graham Finch, Adam DiPlacido Mass timber and CLT construction offers many advantages, such as enhanced modularity, reduced construction schedules, improved thermal performance, and material sustainability. However, mass timber’s propensity to absorb moisture from the environment and the relative vapor impermeability of CLT panels introduces unique challenges when incorporated with the building enclosure. These challenges should be considered during design and construction phases to ensure long-term performance. The VaproSh... |

Bourne Wood has been employed as a building material for thousands of years because it is readily available and easy to work with. Due to a recent push for sustainable construction, the use of mass timber elements, such as cross laminated timber (CLT), is increasing. The Fire Research Team at the USDA Forest Products Laboratory have developed collaborations with universities and other institutions to study the fire resistance properties of CLT and improve their marketability for mid- to high-rise const... |

Bending performance of glulam beams made with different processes
https://www.researchgate.net/publication/327181345... [Mechanical Performance] [Journal Article] 2018 Li, Z & Yang, GS & Zhou, Quan & Shan, B & Xiao, Yan This article presents experimental testing results designed to obtain physical and mechanical properties of glued laminated bamboo (glubam) beams. Two types of glubam beams made with different pre-processed plybamboo boards were tested. One type glubam beam specimens were made with thin layer bamboo strips of about 2 mm thick, and the other were manufactured with thick layer bamboo strips of about 5–6 mm. Test results of the full-scale beams show that the behavior of the glubam beams was elasto-... |

Thermal Response of Timber Slabs Exposed to Travelling Fires and Traditional Design Fires
https://www.researchgate.net/publication/342240247... [Fire Performance] [Journal Article] 2020 Franz Richter, Panagiotis Kotsovinos, Egle Rackauskaite, Guillermo Rein Timber is an innovative and sustainable construction material, but its uptake has been hindered by concerns about its performance in a fire. Current building regulations measure the fire performance of timber using the metric of fire resistance tests. In these tests, the charring rate is measured under a series of heat exposures (design fires) and from this the structural stability is deduced. Charring rates are currently only well known for one heat exposure regime (standard fire), which restri... |

Cross-Laminated Timber Shear Connections with Double-Angled Self-Tapping Screw Assemblies
https://www.semanticscholar.org/paper/Cross-Lamina... [Connectors] [Journal Article] 2016 Afrin Hossain, Ilana Danzig, Thomas Tannert The research presented in this paper examines the shear resistance performance of self-tapping screws (STS) in three-ply cross-laminated timber (CLT) panels. Specifically, the feasibility of using innovative STS assemblies with double inclination of fasteners was investigated for the shear connection of CLT panels. The specimens (1.5×1.5 m) were subjected to quasi-static and reversed-cyclic loading. The tests were set up to approximate pure shear loading, with three-panel CLT assemblies connect... |

Omar Amini, John W. van de Lindt, Shiling Pei, Douglas Rammer, Phil Line, Marjan Popovski 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... |

Ductility Based Force Reduction Factors for Symmetrical Cross-Laminated Timber Structures
https://www.researchgate.net/publication/274959160... [Seismic Performance] [Journal Article] 2015 Marjan Popovski, Shiling Pei, John W. van de Lindt, Erol Karacabeyli Cross-laminated timber (CLT) as a structural system has not been fully introduced in 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 ... |
