Marcelo González-Retamal, Eric Forcael, Gerardo Saelzer-Fuica, Mauricio Vargas-Mosqueda
Products derived from trees have been used by mankind for thousands of years, where timber has a long tradition as an ecological construction material. There is currently an increasing trend in multi-storey timber buildings, because of the projected growth in the demand for housing in urban areas between now and 2050, along with the urgent need for a more sustainable and productive construction industry. The construction of these buildings is now possible thanks to the new advances in architectu...

Mass-Timber Panel (MTP) Industry and its Supply/Value Chain
https://www.researchgate.net/publication/354047896... [Markets] [Conference Paper] 2021
Lech Muszynski, Pipiet Larasatie, Eric N Hansen
The mass-timber panel industry is an exception in the traditional commodity-oriented forest products industry at large, even if one compares it to quite sophisticated engineered wood products like glulam, I-joists or LVL. With possible exception for glulam decks, unidirectional nail-or dowel-laminated timber panels and CLT used for industrial mats, all structural cross-laminated timber panels discussed in this presentation are specialty products, custom produced and fabricated for specific proje...

Seismic performance assessment of a new mass timber-steel hybrid building system
https://www.researchgate.net/publication/362140128... [Seismic Performance] [Conference Paper] 2022
C. ZHANG, C. LOSS
This work investigates how the actual in-plane stiffness of CLT diaphragms alters the seismic response of a multistorey building equipped with a concentrically X-braced steel frame. The details of finite-element model (FEM) of the steel frame and CLT floor in OpenSees [1] are shown in Figure 1. Numerical models of the steel brace and CLT floor are both validated based on experimental datasets [2]. The nonlinear responses of braces—which contributes to the lateral resistance and ductile deformabi...

Long-span CLT-glulam composite flooring system connected with bamboo-based shear connectors: feasibility of design for assembly
https://www.researchgate.net/publication/360768901... [Connectors] [Conference Paper] 2022
Y. Diao, C. Loss
Composite flooring systems built with CLT-glulam ribs have a higher strength-to-weight ratio compared to the concrete-steel composites; thus, it can result in an economical solution for spans over 12 meters. In practice, the lack of studies on the structural performance of such CLT-glulam composites often leads to the oversize of the floor members. In addition, shear connectors design is crucial and drives to the structural efficiency of the floor assembly. In this paper, the long-span CLT-glula...

Carrero Roa, Tulio Enrique
Currently, it can be considered that there are four dominant systems of structural timber resistant to side shear, such as shear walls with a light frame timber structure (Light Frame Timber Buildings, LFTB) and walls of glued laminated timber shear panels (Glued Laminated Timber (GLULAM) cross laminated (Cross Laminated Timber, CLT) and microlaminated wood walls (Laminated venner lumber, LVL). Over time, an improvement in the seismic behavior of traditional wooden structures has been shown with...

Design for a Reconfigurable Mass Timber Building System
https://digital.lib.washington.edu/researchworks/h... [Design/Architectural aspects] [Thesis/Dissertation] 2022
Chuou Zhang
Mass timber products like glulam and cross-laminated timber(CLT) can store / sequester carbon in building stocks for as long as the building components remain in use. For this carbon reduction to have a significant impact, mass timber products must not release the carbon emission back to the atmosphere in their end-of-life. The end-of-life options for wood products are often reduced to landfills, energy production, reprocess, and recycling facilities. Most buildings with mass timber components a...
