Cross-laminated timber (CLT) wall systems are composed of massive timber panels that are fastened together and to the horizontal elements (foundations or intermediate floors) with step joints and mechanical connections. Due to the high in-plane stiffness of CLT, the shear response of such systems depends strongly on the connections used...
This paper presents an experimental study on dowelled connections in cross-laminated timber (CLT) and laminated veneer lumber (LVL) using 20-mm mild steel dowels and internal steel plates. Connections designed to fail in brittle row shear and group tear-out were tested under monotonic loading...
The updated CLT Handbook Canadian 2nd Edition will be released in early 2020.
This Handbook provides key technical information related to the manufacturing, design and performance of CLT in construction in the following areas:
Cross-laminated timber manufacturing
Structural design of cross-laminated timber elements
Seismic performance of cross-laminated timber buildings
Connections in cross-laminated timber buildings
Duration of load and creep factors for cross-laminated timber panels
Vibration performance of cross-laminated timber floors
Fire performance of cross-laminated timber assemblies
Acoustic performance of cross-laminated timber assemblies
Building enclosure design of cross-laminated timber construction
Environmental performance of cross-laminated timber
Finally, this comprehensive Handbook provides immediate support for the design and construction of CLT systems as alternative solutions in building codes. Additionally, it provides technical information for implementing CLT systems in building codes and standards.
In Phase I of Developing Large Span Two Way CLT Floor System (2017-18) we studied the performance of a steel plate connection system for the minor direction of CLT plates. The connected specimens had higher stiffness and strength compared to intact members under bending. In Phase II (2018-19) we designed and tested another connector based on...
In Phase I (2018-19) of this project on Prefabricated Heavy Timber Modular Construction, three major types of connections used in a stackable modular building were studied: intramodule connection, inter-module vertical connection, and inter-module horizontal connection. The load requirement and major design criteria were identified...
