Full-scale experimental testing of timber beam-to-column connections under simulated column-removal scenarios. The three-actuator setup applies coordinated loading to reproduce the combined axial tension, shear force, and bending moment that develop as the damaged structure undergoes large displacements and mobilizes tensile catenary action. The tests capture the interaction among these demands, connection deformation, load redistribution, and failure progression, providing data to improve the robustness and progressive-collapse resistance of mass-timber buildings.

Full-scale reversed-cyclic testing of mass-timber beam-to-column moment connections to evaluate their strength, stiffness, ductility, rotation capacity, energy dissipation, and failure mechanisms. The experimental program examines how connection detailing and dowel configuration influence cyclic performance and damage progression. The results support the development and validation of reliable design methods for ductile and resilient mass-timber moment-resisting frames in seismic regions.

Development of a systematic capacity-based design methodology for timber braced frames in which ductility and energy dissipation are deliberately concentrated within the end-brace connections. The expected connection capacities are used to determine the demands on the braces, beams, columns, and non-dissipative connections, establishing a clear strength hierarchy that protects these components from unintended inelastic response. The methodology accounts for force redistribution following connection yielding and applies capacity-protection factors to the remaining structural components.

Experimental evaluation and full-scale cyclic testing of replaceable, yield-controlled perforated steel plate fuses for mass-timber lateral force-resisting systems. The research examines how fuse geometry and detailing influence strength, stiffness, ductility, energy dissipation, and failure mechanisms. By concentrating inelastic damage within replaceable steel components, these devices protect the primary timber members and connections while improving seismic resilience and post-earthquake reparability.

Development and validation of prefabricated, preservative-treated mass-timber basement and foundation wall systems through material and connection testing, full-scale structural experiments, and long-term field monitoring. The research evaluates structural resistance to soil, gravity, and lateral loads; wall configurations with and without openings; moisture transfer; hygrothermal performance; durability; constructability; and waterproofing and connection details. A full-scale field demonstration integrates laboratory findings with life-cycle assessment, environmental impact analysis, and economic evaluation to support standardized design methods and practical implementation in Canadian residential construction.

Three-dimensional nonlinear finite-element investigation of steel beam-to-column shear connections under column-removal scenarios. The research examines the behaviour of shear-tab, single-angle, and WT connections subjected to the combined shear, axial tension, and bending-moment demands that develop at large rotations following the loss of a supporting column. Validated numerical models are used to evaluate connection strength, deformation capacity, failure progression, and the transition from flexural and compressive-arching response to tensile catenary action. The findings demonstrate the inherent robustness of conventional steel connections and support practical design recommendations for improving resistance to disproportionate collapse.

Large-scale experimental testing and advanced finite-element modelling of rehabilitation solutions for aging pipelines subjected to operational demands and geotechnical ground movements. The research evaluates steel sleeves, composite-wrap systems, and emerging repair technologies, with particular emphasis on load transfer, local stress and strain concentrations, axial strain capacity, and failure mechanisms under severe bending and deformation. The findings support the development of safer and more reliable repair methodologies that extend pipeline service life, reduce the need for replacement, and improve the resilience of critical energy infrastructure.

Development and evaluation of low-carbon seismic-upgrading solutions for existing steel buildings using timber concentrically braced systems. The research investigates the structural performance, environmental benefits, practical detailing, and implementation challenges of integrating timber braces into existing steel frames. Numerical and analytical studies are used to develop efficient brace configurations and connections that enhance seismic performance, avoid brace buckling, reduce embodied carbon, and extend the service life of existing buildings.

Customized commercial testing of timber, steel, composite materials, connections, and structural components. Testing programs can evaluate mechanical properties, strength, stiffness, ductility, cyclic response, and failure mechanisms using universal testing machines and actuator-based setups. Tests may follow applicable ASTM, CSA, and ISO standards or use project-specific protocols developed in consultation with industry partners.

Large-scale commercial testing of structural assemblies and complete systems under monotonic, cyclic, and combined loading conditions. Using the Morrison Structures Laboratory’s strong floor, strong wall, and high-capacity actuators, testing programs can assess load paths, system strength and stiffness, deformation capacity, energy dissipation, damage progression, and failure mechanisms. Customized test setups, instrumentation plans, data analysis, and technical reporting can be developed to support product evaluation, design validation, and research and development.
