N2 Method - Adaption to CLT Structures
https://www.researchgate.net/publication/330354733... [Seismic Performance] [Conference Paper] 2018 Johannes Hummel, Werner Seim, Sascha Schwendner The N2 method is the only displacement-based design (DBD) procedure which was incorporated in Eurocode 8 [1]. However, the N2 method has some limitations regarding the application to cross-laminated timber (CLT) structures, which because of the background of the reduction factor Rµ used to create the response spectrum for DBD. The paper will present a new relationship of the reduction factor Rµ for CLT structures which is derived by means of a study on a set of single degree of freedom systems. ... |

The Seismic Behavior of Cross-Laminated-Timber Composite Slab in High-Rise Building
http://www.ijetch.org/index.php?m=content&c=index&... [Seismic Performance] [Journal Article] 2018 Xin Yin This paper discusses the seismic performance of Cross-Laminated-Timber (CLT) floor slab in high-rise buildings. Due to its lower ductility and brittle failure mechanisms, CLT shows many advantages that can offer to construction sectors such as CLT walls or floor slabs. Substituting ultra lightweight slab material (CLT) for reinforced concrete floors or roofs can utilize its advantages to strengthen structural capacities. Moreover, the CLT-to-Steel Connection test illustrates that these connectio... |

Wetting and drying performance of cross-laminated timber related to on-site moisture protections: Field measurements and hygrothermal simulations
https://www.e3s-conferences.org/10.1051/e3sconf/20... [Moisture/Durability] [Conference Paper] 2020 Lin Wang, Jieying Wang, Hua Ge Cross-laminated timber (CLT) panels are increasingly used in mid-rise buildings or even taller structures in North America. However, prolonged exposure to moisture during construction and in service is a durability concern for most wood products including CLT. To investigate practical solutions for reducing on-site wetting of mass timber construction, CLT specimens with a range of moisture protection measures, in six groups were tested in the backyard of FPInnovations’ Vancouver laboratory from ... |

Fire Design of Mass Timber Members - Code Applications, Construction Types and Fire Ratings
https://www.woodworks.org/wp-content/uploads/Wood_... [Fire Performance] [Others] 2019 Richard McLain, Scott Breneman For many years, exposed heavy timber framing elements have been permitted in U.S. buildings due to their inherent fire-resistance properties. The predictability of woods char rate has been well-established for decades and has long been recognized in building codes and standards. Today, one of the exciting trends in building design is the growing use of mass timber-i.e., large solid wood panel products such as cross-laminated timber (CLT) and nail-laminated timber (NLT)-for floor, wall and roof c... |

[Vibration/Acoustic Performance] [Journal Article] 2020 Antonino Di Bella, Milica Mitrovic The growing diffusion of cross-laminated timber structures (CLT) has been accompanied by extensive research on the peculiar characteristics of this construction system, mainly concerning its economic and environmental benefits, lifecycle, structural design, resistance to seismic actions, fire protection, and energy efficiency. Nevertheless, some aspects have not yet been fully analysed. These include both the knowledge of noise protection that CLT systems are able to offer in relation to the pos... |

Cross-Laminated Timber (CLT) - APA – The Engineered Wood Association
https://www.apawood.org/cross-laminated-timber... [General Information] [Web Page] 2020 APA Cross-laminated timber (CLT) is a large-scale, prefabricated, solid engineered wood panel. Lightweight yet very strong, with superior acoustic, fire, seismic, and thermal performance, CLT is also fast and easy to install, generating almost no waste onsite. CLT offers design flexibility and low environmental impacts. For these reasons, cross-laminated timber is proving to be a highly advantageous alternative to conventional materials like concrete, masonry, or steel, especially in multi-family an... |

[Seismic Performance] [Thesis/Dissertation] 2016 Caleb Goertz This thesis discusses a novel timber-steel core wall system for use in multi-storey buildings in high seismic regions. This hybrid system combines Cross Laminated Timber (CLT) panels with steel plates and connections to provide the required strength and ductility to core walled buildings. The system is first derived from first principles and validated in SAP2000. In order to assess the feasibility of the system it is implemented in the design of a 7-storey building based off an already built con... |
