Abstract
This project will optimize the strength, stiffness, vibration characteristics, acoustic qualities and fire resistance of cross-laminated floor systems utilizing a composite concrete and cross-laminated timber product. This project includes development, testing and optimization of an economical shear connector (to connect the CLT panel to the concrete slab) that will be compared with existing screw and steel plate solutions. The resulting prototype floor system will be tested at full scale.

Abstract
Constructing buildings with CLT requires development of novel panel attachment methods and mechanisms. Architects and engineers need to know the engineering strength properties of connected panels, especially in an earthquake prone area. This project will improve knowledge of three types of wall panel connections: wall-to-floor, wall-to-wall, and wall-to-foundation. Testing will determine the strength properties of metal connectors applied with diffferent types and sizes of screw fasteners. The data will be used to develop a modeling tool that engineers can use when designing multi-story buildings to be constructed with CLT panels.

Abstract
Currently, only light frame wood-based shearwall and braced and moment-resisting frames are given in the NBC 2015 as acceptable solutions, with the height limit for these SFRSs in high seismic zones being 20 m (6 storeys). There is no acceptable solution for using Timber SFRS in buildings more than 20 m high in high seismic zones. The Tall Wood building projects in Canada have been following the “Alternative Solution” path with supporting test data and analysis that could demonstrate equivalent or better performance than building and fire code or local condition requirements, and were approved on a case-by-case basis by the Authority Having Jurisdiction (AHJ). The Tall Wood projects have been and will be faced with different level of difficulties and challenges depending on the familiarity of AHJ with tall wood construction. Furthermore, there are no consistent procedure and performance criteria to analyze and evaluate the Timber SFRS in tall mass timber buildings that could be referenced by the AHJ. This project is to undertake the work related to:
Phase I: development of a Technical Guide with a procedure for evaluation of the seismic performance of Timber SFRS in tall mass timber buildings.
Phase II: evaluation of an example solution of Mass Timber SFRS in accordance with the developed Technical Guide as a “Demo” project.

Abstract
This project will generate three benchmark data sets for multistory CLT building moisture performance in different climate zones. Data will include moisture contents at key wood components and high moisture risk locations throughout the buildings. A relatively simple, but fully validated, numerical model for analyzing similar building moisture performance will be recommended. These results will be useful for structural engineers and architects to accurately consider moisture in their design of mass timber buildings.
