Design Guidance for Cross-Laminated-Timber Structures using Self-Tapping-Screws
There is an acute need for research to develop value-added applications for wood and wood products such as Cross-Laminated-Timber (CLT). One prominent target area are mid- and high-rise structures. In seismic regions, such as Western Canada, connectors must provide ductility to otherwise rigid building systems composed of CLT panels. There are a number of options available, one of the most promising are Self-Tapping-Screws (STS). The objective of the project is to develop design guidance for CLT assemblies connected by STS for large structures, considering seismic loads. Experimental, numerical and analytical work on the material, component and system levels will be combined to achieve this objective. MiTiCon will directly benefit by having first hand access to the results, creating design guidance and establishing a relation to a highly qualified potential future employee. The project can contribute to increasing the market share of wood products in the North American construction sector, and thus, the project contributes to reducing the carbon footprint of structures.
