“…Timber connections with thin-walled metal parts have been gradually replacing traditional carpentry joints as the formers usually possess higher ductility, less reduction of cross section and easier in-situ implementation. Remaining sufficiently anchored during high-intensity events and the ability to deform plastically for the connectors are critical for CLT structures (Sejkot et al, 2015). Steel angle brackets (for horizontal sliding forces) and hold-downs (for vertical uplift forces) are the most common types of such connectors (Tomasi and Smith, 2014).…”

Connections are arguably one of the most critical components controlling the structural performance and failure modes of mass timber structures. Over the last two decades, demands for stronger and energy dissipative connections have been raised with increased application of mass timber products in larger and taller buildings. This paper presents numerical analyses of novel mass timber connections used in cross laminated timber structures. The connections are developed by MyTiCon with BB Stanz- und Umformtechnik GmbH angle bracket. Despite being relatively thin, these angle brackets could show comparable load resistance with thicker ones due to the reinforced web and folded edges. The commercially available finite element software ABAQUS was used to develop three dimensional (3D) numerical models to simulate the performance of angle bracket connections under different load combinations. The modelling analysis involves two phases: (1) to determine the most efficient fastener type and setup for the angle brackets connected to CLT wall and floor panels, and (2) to evaluate the capacity of angle brackets connected to CLT wall and floor panels in various loading scenarios. The findings of this study provide an insight into the behaviour of this new angle bracket connections and will be used in the design of the experimental tests in the next phase.
