The potential of using mass-timber products for larger and non-residential structures with longer floor spans is increasingly being explored in Canada. To achieve large and open spaces, timber frame structures consisting of beams and posts are adopted. To control vibration and deflection, deep Glulam beams are used to support the floors, and specifically in large-span post-and-beam construction, often pre-engineered beam hangers are used. However, this use of deep beams and pre-engineered connectors creates a new challenge in column design, which is not accounted for or addressed in the current design practice, namely secondary bending moments are induced in the columns. The goals of this research partnership is to investigate numerically and experimentally the combined rotational moment and shear force capacity of engineered beam hanger connections, and evaluate the impact of the secondary moments induced by deep-beam connections on the structural performance of columns, connections, and the lateral load resisting system of timber structures.
