The elastic and ductile behaviour of CLT wall-floor connections and the influence of fastener length
https://www.sciencedirect.com/science/article/pii/... [Connectors] [Journal Article] 2019 Conan O'Ceallaigh, Annette 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... |

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 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 ... |

Elastic properties of full-size mass timber panels: Characterization using modal testing and comparison with model predictions
https://www.researchgate.net/publication/311732936... [Mechanical Performance] [Journal Article] 2017 Jaianhui Zhou, Ying Hei Chui, Meng Gong, Lin Hu Mass timber panel products are leading the evolution of wood construction throughout the world. In-plane elastic properties of mass timber panels are critical in serviceability design, especially when two-dimensional mechanical behaviour is considered. In this study, the moduli of elasticity (MOE) in major and minor strength directions (Ex and Ey), and in-plane shear modulus (Gxy) of 51 industrial size cross laminated timber (CLT) panels, 4 multi-ply solid wood panels (MSWP) were measured by a m... |

Thermal property and flame retardancy comparisons based on particle size and size distribution of clays in ethylene vinyl acetate (EVA) adhesive sheets for cross-laminated timber (CLT)
https://link.springer.com/content/pdf/10.1007%2Fs0... [Fire Performance] [Journal Article] 2019 Jung-Hun Lee, Ji-Won Park, Hoon Kim, Seong-Wook Jang, Hyun-Joong Kim, Yoon Choi Cross-laminated timber (CLT) is widely used as a building material, and recent interest in this material has increased rapidly due to environmental problems. For instance, the phenol resorcinol formaldehyde (PRF) used as an adhesive in CLT can release toxic gases during a fire, resulting in adverse health effects. These properties cause concern regarding the use of CLT as a building material and restrict its use. In this study, the effects of the particle size and size distribution of clays on t... |

Influence of the Connection Modelling on the Seismic Behaviour of Crosslam Timber Buildingsf Crosslam Timbe
https://dx.doi.org/10.1007/978-94-007-7811-5_61... [Seismic Performance] [Journal Article] 2014 I. Sustersic, B. Dujic, Massimo Fragiacomo The paper investigates the influence of modelling different types of connections in multi-storey cross-laminated timber buildings. The importance of modelling the connection flexibility in the prediction of the natural vibration periods and the base shear force of a crosslam building is demonstrated using linear-dynamic analysis. The building’s global ductility and peak ground acceleration were compared using non-linear static and dynamic analyses, demonstrating that the former may lead to non-c... |

Modeling the bending vibration of cross-laminated timber beams
https://link.springer.com/content/pdf/10.1007/s001... [Vibration/Acoustic Performance] [Journal Article] 2017 Bart Van Damme, Stefan Schoenwald, Armin Zemp Cross-laminated timber (CLT) is an economical construction material combining good structural properties and environmental advantages. Due to the layered geometry and the associated internal stress boundary conditions, modelling its dynamic behavior is complex. However, accurate vibration level estimations are necessary to estimate the sound insulation performance of CLT constructions. This paper outlines a method to determine the relevant elastic constants and the appropriate equations of motio... |

What is tall timber? Towards the formal classification of timber as a material of tall building design
https://www.researchgate.net/publication/327322198... [Markets] [Conference Paper] 2018 Robert Foster, Thomas Reynolds, Michael Ramage The emergence of taller buildings using engineered timber as a structural material raises important questions about the language that is used to describe tall buildings. In the absence of formal definitions it is difficult to make meaningful comparisons between buildings using different materials, structural systems and building forms. Claims to the title of 'tallest timber building' are frequently made and may be subject to dispute. This paper discusses the role of the CTBUH Criteria for Defini... |

[Connectors] [Journal Article] 2015 Igor Gavric, Massimo Fragiacomo, Ario Ceccotti An extended experimental programme on typical cross-laminated (CLT) connections was performed at IVALSA Trees and Timber Institute. The paper discusses the results of monotonic and cyclic tests in shear and tension (pull-out) carried out on hold-downs and steel angle brackets used to anchor the wall panels to foundations or to connect wall panels to floor panels. Mechanical properties such as strength, stiffness, energy dissipation, impairment of strength and ductility were evaluated and are cri... |
