Abstract

Multiple knife plate and external steel plate deep-beam glulam connections were investigated in a series of destructive tests within the Infrastructure Testing and Applied Research laboratory at Portland State University. The goal of these tests was to better understand the failure mode and ultimate load capacity of the large-scale glulam moment connections. Two different types of tests were performed on each connection; one with axial loading, and another loaded in flexure. The first, smaller, axial tests were conducted to inform the later, much larger, bending tests. The results of these tests helped to develop future designs as well as provide adequate proof of concept for an ongoing project.

Each of the failure types were cataloged and the ultimate loads of each tested connection were compared to estimated design capacities. Block shear and shear type splitting were the most observed failure types. The results demonstrated the knife plate connection consistently failing before the expected load was reached, whereas the external steel plate connection regularly exceeding the expected loads.
