“…When designed properly with steel connectors and CLT elements, the structure can exhibit superior seismic performance by leveraging the high strength-to-weight ratio of wood members and the high ductility of steel components [3]. A good understanding of connections in CLT structures is needed to better predict the performance of the structures and avoid unexpected failures, e.g., caused by the out-of-plane movements under wind and seismic loads [4]. Some scholars [5][6][7][8][9][10] already used advanced modelling techniques in Abaqus® to predict the performance of structures connected by the steel components, ring nails or screws.…”

Mechanical connections in wood structures typically consist of structural members connected with combination of cold-formed thin-walled steel angle brackets and fasteners in forms of nails or screws. Design of these steel connectors is typically based on short-term monotonic load bearing capacities. Observations from experimental testing indicate that their failure modes and resistance to a cyclic loading should be checked carefully to prevent the thread of sudden collapse of structures using these connections. This paper presents the experimental results of connections of CLT elements connected together by angle brackets and subjected to the external cyclic loading. Special focus is made on connections using heavy duty screws as fasteners. Results of experimental testing are compared to results of testing of similar connections using ring nails as fasteners. In addition, numerical simulations are made with aim to predict the failure modes and the load bearing capacities of experimentally tested connections.
