Design model for fire exposed cross-laminated timber
https://www.researchgate.net/publication/281458489... [Fire Performance] [Conference Paper] 2010
Joachim Schmid, J. König, Jochen Köhler
Cross-laminated timber (CLT) is increasingly used in medium-rise timber buildings, for the time being up to eight storeys, among other reasons for cost effectiveness and robustness. This paper presents a simple design model using the effective cross-section method for the structural fire design, i.e. the determination of the mechanical resistance with respect to bending (floors). Performing advanced calculations for a large number of lay-ups of various lamination thicknesses, using the thermal a...

Cross-laminated timber engineering : improvement and application
https://ir.library.oregonstate.edu/concern/graduat... [Seismic Performance] [Thesis/Dissertation] 2014
Anthonie Kramer
The first study presented is an assessment of the viability of hybrid poplar for use in CLT panels. Hybrid poplar is a low density species, which is not typically considered for structural applications. Low density species have the potential to improve the structural efficiency of CLT panels. The tests conducted are based on the qualification of panels outlined in the ANSI/APA PRG-320: Standard for Performance-Rated Cross-Laminated Timber to determine the structural viability of the CLT panels. ...

Simplified Mechanistic Model for Seismic Response Prediction of Coupled Cross-Laminated Timber Rocking Walls
https://ascelibrary.org/doi/10.1061/%28ASCE%29ST.1... [Seismic Performance] [Journal Article] 2019
Z. Jin, S. Pei, H. Blomgren, J. Powers
A simplified mechanistic model is developed in this study to predict the lateral load resistance of coupled rocking walls made from cross-laminated timber (CLT) panels as an alternative to finite-element modeling. The model is derived in an incremental format in order to capture the nonlinear behavior of the rocking wall, including crushing of the corners and inelastic response of interpanel connectors. The backbone curve and limit states generated using the proposed model are verified through a...

Comparative assessment of shape related cross-laminated timber building typologies focusing on environmental performance
https://www.sciencedirect.com/science/article/pii/... [Environmental Performance] [Journal Article] 2018
Vesna Zegarac Leskovar, Maja Zigart, Miroslav Premrov, Rebeka Kovacic Lukman
Consideration of environmental impacts caused by buildings with the aim of reducing environmental loads has become a high priority for the construction sector. Since the geometry and the size of buildings, two of the multiple design factors, are assumed to affect the building environmental profile, the current paper discusses the influence of the building shape on the building environmental performance. Thus, a life-cycle assessment (LCA) was conducted for five simplified reference building mode...

In-Plane Stiffness of Hybrid Steel–Cross-Laminated Timber Floor Diaphragms
https://ascelibrary.org/doi/10.1061/%28ASCE%29ST.1... [Alternative/Hybrid Configurations] [Journal Article] 2018
Cristiano Loss, Stefano Rossi, Thomas Tannert
The use of hybrid structural systems formed by combining wood with other materials provides engineers with a wide range of solutions to satisfy code requirements for mid- and possibly high-rise buildings. Hybrid wood-based systems include a wide range of construction methods and different levels of integration of materials and components. The research discussed in this paper presents an innovative hybrid timber-steel solution for floor diaphragms developed by joining cross-laminated timber panel...

Vahid Mahdavifar, Andre R. Barbosa, Arijit Sinha, Lech Muszynski Rakesh Gupta, Steven E. Pryor
The development of cross-laminated timber (CLT) has created new opportunities for the use of lumber from low-grade and low-density species in structural applications. In order to ensure the structural viability of CLT panels with such material, hybrid layups have been proposed, in which the low-grade and low-density lumber was placed in core layers, while high-grade (#2 or better) and high-density lumber was used in the face layers. One major criterion in the evaluation of hybrid CLT for structu...

Flanking floor impact sound insulation in cross laminated timber model building for experiment

A. Hiramitsu1, T. Otsuru, R. Tomiku, K. Harada
The Act for Promotion of Use of Wood in Public Buildings (Law No. 36 of 2010 of Japan) was enforced in 2010. The promotion of the use of wood can contribute to the prevention of global warming etc. A public building in a low layer is supposed to attempt making to timber construction by this act. Moreover it is expected that the building such as apartment houses comes to be made from timber construction. For effective use of the Japanese wood, CLT (Cross Laminated Timber), which had been used in ...

Modelling of fire performance of Cross Laminated Timber (CLT) panels

Trong Tuan Tran, Mourad Khelifa, Ali Nadjai, Marc Oudjene, Yann Rogaume
A numerical method has been developed to incorporate the effects of heat transfer in a CLT panel exposed to fire. The procedure has been added into the software package Abaqus [1] as a user-defined subroutine (Umatht), and has been verified using both time-and spatially dependent heat fluxes in two- and three-dimensional problems. The aim is to contribute to the development of simulation tools needed to assist structural engineers and fire testing laboratories in technical assessment exercises. ...

Motoshi Sato, Hiroshi Isoda, Yasuhiro Araki, Takafumi Nakagawa, Naohito Kawai, Tatsuya Miyake
A national research project to investigate proper structural design methods for cross-laminated timber (CLT) buildings has been initiated by a subsidiary of the Ministry of Land, Infrastructure, Transport and Tourism of Japan since 2011. In the final stage of the project, shaking table tests were conducted for CLT buildings designed according to a proposed structural design procedure which confirmed damage limit state, safety limit state, allowable stress, and ductile factors, etc. This paper p...

Ballistic Performance of Cross-Laminated Timber (CLT)
https://www.sciencedirect.com/science/article/pii/... [Other] [Journal Article] 2018
K. Sanborn, T.R. Gentry, Z. Koch, A. Valkenburg, C. Conley, L.K. Stewart
Cross-laminated timber (CLT) is a relatively new building material that has gained recent attention in the United States construction industry. CLT is a prefabricated, engineered wood product, composed of three or more plies of lumber with alternating ply directions. CLT is relatively strong and stiff, with the potential to meet the requirements for structures that are subjected to a variety of loading conditions. While CLT’s response to static, dynamic (i.e., seismic), and fire loads has been c...

Cyclic behaviour of glulam shear walls with bolted connections
http://link.springer.com/10.1007/s00107-016-1020-7... [Connectors] [Journal Article] 2016
Daniela Wrzesniak, Massimo Fragiacomo
Dowels and bolts are well established types of fasteners for timber connections. They are fast and easy to assemble which made them become a common solution for joining heavy timber elements. This study investigates the feasibility of bolted connections as a possible anchoring solution for heavy shear walls under seismic loads. Fully reversed cyclic tests were performed on glued laminated (glulam) timber shear walls with un-reinforced and reinforced bolted connections. This study builds up on a ...

Building a Case for Building with Wood

Rebecca Wallace
Brittany Patterson, an E&E (energy and environment) reporter for ClimateWire, recently visited the Forest Products Laboratory (FPL) to learn all she could about cross-laminated timber (CLT) and building tall with wood. After a day at the Lab and talks and visits with others working with CLT, Brittany amassed enough information to author a comprehensive article on the current state, and future promise, of building mid- to high-rise buildings with wood in the United States. The article, titled Sa...
