Summary
This paper discusses the design of timber diaphragms, in response to the growing interest in multi-storey commercial timber structures, and the lack of guidance or regulations regarding the seismic design of timber diaphragms...
In the 2010 National Building Code of Canada (NRC 2010), certain structures can be designed for seismic loads using an equivalent static force procedure. In these provisions, elastic design forces are reduced by a ductility factor, Rd, which accounts fo...
This paper describes experiments conducted to develop a resilient lateral force resisting wall system that combines cross-laminated timber (CLT) panels with vertical post-tensioning (PT) to provide post-event re-centering. Supplemental mild steel U-shaped flexural plate devices (UFPs) are intended to yield under cyclic loading while the PT...
Timber building construction has been traditionally utilized to reduce inertial demands in high seismic regions. Applications in the United States however, are often limited to low-rise buildings of light-wood construction with distributed load bearing shear walls. Recent advancements in timber technologies are pushing mass timber systems...

Summary
Assemblies with glued-in rods allow architectural freedom. They are in fact invisible since they are found in the mass of the structural element. Some work has begun to document this type of assembly by considering static tests in single-sided traction and single-sided creep tests (Verdet, 2016). In order to continue this effort to specify the limits of this type of assembly, it is proposed to consider the lateral forces for assemblies with single and multiple rod connections. This project will therefore aim to document the ability of these assemblies to carry lateral loads.
Seismic damage to floor diaphragms because of displacement incompatibilities are a point of concern in many structures. This paper studies the behaviour of timber diaphragms subjected to frame elongation and rocking of walls in post-tensioned timber buil...
