Cyclic behavior of foundation-wall connection in cross laminated timber shear walls
https://www.researchgate.net/publication/321757681... [Connectors] [Journal Article] 2017
Franco Benedetti, V Rosales, Alexander Opazo
Within the scope of sustainable construction, cross laminated timber (CLT) has a number of attributes that makes it an attractive alternative to build mid-rise buildings. Nevertheless, since the CLT elements are almost rigid panels, a critical matter of the seismic behavior of this construction system is the connections hysteretic response, because these links are responsible of giving a suitable ductility capacity and energy dissipation to the CLT structure subjected to seismic movement. Beside...

Hysteretic Response of Metal Connections on Hybrid Cross-Laminated Timber Panels

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...

https://www.researchgate.net/publication/239390908... [Connectors] [Journal Article] 2003
Kip Gatto, Chia-Ming Uang
Standard construction 2.4 mx 2.4 m woodframe shearwalls were tested using different loading protocols. The CUREE-Caltech protocols, recently developed by Krawinkler in 2001, were compared with other, previously used protocols. The following protocols were considered in the study: monotonic, CUREE-Caltech standard (CUREE), CUREE-Caltech near-fault, sequential phased displacement (SPD), and international standards organization. Findings from the research indicate that loading sequence has a signif...

Modeling of the seismic behavior of structures of Cross-Laminated Timber panels
https://www.researchgate.net/publication/318277760... [Seismic Performance] [Journal Article] 2017
Beatriz González Rodrigo, Alberto Fraile, Juan Carlos Mosquera
The construction system based on cross-laminated timber (CLT) panels is developing fast in recent years after its initial design in the 90s. The good behavior of the system to fire and seismic actions is facilitating its penetration in the building market for small and medium height buildings. CLT-based structural systems present good ductility and energy dissipation capacity. Energy dissipation is achieved through metal connections, as these elements work actively to provide strength, stiffness...

In addition to combustible, heavy timber and noncombustible construction, a new construction type is presently being considered for inclusion into the National Building Code of Canada (NBC). Encapsulated mass timber construction (EMTC) is proposed to be defined as the “type of construction in which a degree of fire safety is attained by the use of encapsulated mass timber elements with an encapsulation rating and minimum dimensions for the structural timber members and other building assemblies....

The COST Action FP1402 is a research network established under the aegis of the COST domain "Forests, their Products and Services". The aim of the Action was to overcome the gap between broadly available scientific results and the specific information needed by designers, industry, authorities and code committees, providing transfer for practical application in timber design and innovation. Working Group 2 "Solid/Massive Timber", aimed on collecting, discussing,assessing, harmonizing and condens...

Novel steel tube connection for hybrid systems

Amidst the traditional dominance of wood-frame construction approaches for residential buildings, innovative hybrid structures (e.g., timber-concrete and timber-steel methods) are achieving greater popularity. In such hybrids, materials with different properties are combined to utilize the best of each and overcome their individual limitations. In particular, timber-steel hybridized buildings are very promising with several advantages such as short construction times and heightened overall resil...

Tall Mass Timber
https://www.awc.org/tallmasstimber... [Tall Buildings] [Web Page] 2018
American Wood Council
Tall mass timber is an industry term to identify mass timber buildings, constructed of mass timber elements, that exceed current height limits for wood buildings set by the International Building Code. Mass timber includes any product currently permitted for use in Type IV construction, such as Cross Laminated Timber, Structural Composite Lumber, glued-laminated timber, and large section sawn lumber. Because of the unique structural and fire resistance characteristics of solid timber walls and ...

Cross-laminated timber (CLT) panels are relatively new engineered wood products that can be used as load bearing walls, floors and roof elements in innovative and high quality modern timber structures. The fire behavior of cross-laminated timber panels requires careful evaluation to allow the expansion of CLT elements usage in buildings. A University of British Columbia study has been conducted at the Trees and Timber Institute CNR-IVALSA in San Michele all’Adige, Italy to experimentally evaluat...

Overstrength of large-scale dowelled connection in CLT
https://www.researchgate.net/publication/331315629... [Connectors] [Journal Article] 2018
Tobias James Smith, Li Minghao, Lisa Ottenhaus
This paper presents an evaluation of overstrength based on an experimental study on large-scale dowelled connections in Cross Laminated Timber (CLT). In timber structures, ductility is often achieved through plastic deformation of steel fasteners in connections. In order to avoid brittle failure and ensure that ductile system behaviour and energy dissipation can be achieved under seismic loading, the overstrength of connections needs to be well understood. Overstrength is generally defined as th...

Two innovative hybrid steel-wood seismic force-resisting systems have been developed that utilize the energy dissipation capabilities of advanced structural steel systems to improve the seismic performance and design of heavy timber structures. Conceptual designs of these two systems are presented: first, a buckling restrained braced frame adapted for wood buildings using glued-in rods; and second, a ductile and replaceable steel reduced beam section connection adapted for wood buildings using a...

Behaviour factor for innovative massive timber shear walls
https://www.researchgate.net/publication/275723190... [Mechanical Performance] [Journal Article] 2015
Luca Pozza, Roberto Scotta, Davide Trutalli, Andrea Polastri
Four massive wooden shear walls were analysed via experimental tests and numerical simulations. The specimens differ mainly in the method used to assemble the layers of timber boards: two of them are the well-known Cross-Laminated-Timber panels with glued interfaces, the other two are innovative massive timber panels adopting steel staples or wooden dovetail inserts to connect the layers. Quasi-static cyclic-loading tests were performed for each wall and main results are presented and analysed. ...
