Tensile Strength Evaluation Of Glulam Connection With Screw Fasteners, Bradley Sharpshair
Civil and Environmental Engineering Master's Project Reports
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 …

Lateral Deformation Behavior Of Mass Timber Beam To Column Gravity Connection, Tyler James Williams
Civil and Environmental Engineering Master's Project Reports
A beam-to-column connection consisting of glulam beam and column and cross laminated timber floor slab was developed and experimentally evaluated for use in buildings that are expected to undergo earthquake-induced lateral drift. The connection utilized a passive gap closure mechanism designed to allow beam rotations during lateral drift while minimizing residual separation between the beam and the column following an earthquake. Full scale cyclic experiments were used to validate the connection’s minimal rotational stiffness and demonstrate low damage performance for lateral drifts exceeding 4.5% drift. The connection exhibited no degradation in gravity load capacity throughout the imposed lateral deformations. An …
