Summary
Although engineered wood products such as glued laminated timber (glulam) and cross-laminated timber (CLT) have successfully eliminated the flaws inherently exist in conventional wood products, they are still not comparable with steel and concrete in terms of strength and stiffness. Among all different options for reinforcement, Carbon Fibre is relatively popular due to its high tensile strength, low weight, and easy installation. This study presents an analysis of flexural stiffness and stress distributions of CLT panels reinforced with carbon fibre mats, based on an analytical method and finite element method (FEM).

Summary
An increasingly popular composite floor system consists of a Mass Timber Panel (MTP) connected to a concrete slab or topping with mechanical connectors such as Self-Tapping Screws (STS) and a sound insulation layer in between. The concrete topping provides not only structural functions, but also help to enhance acoustic and fire performances. To facilitate the design of these floor systems that meet the criteria of strength, deflection, vibration, acoustics, and fire, pre-determined allowable spans in the format of a table will be beneficial. This report presents the procedure to develop a span table showing allowable spans for specific combinations of timber panel size and grade, concrete thickness, and connection properties.

Summary
The objective of this research is to develop efficient panel-to-panel connection details, and optimum floor configuration, including rigging details, for handling in the factory and at the construction site. Computer modelling will be conducted to develop preliminary recommendations on panel-to-panel connection details and optimum floor panel configuration. These recommendations will then be validated by a testing program in the laboratory.

Summary
The objective of this research is to develop a model to predict the distribution of loads within connections with multiple self-tapping screw fasteners and steel side plates, and use this model to predict the strength and stiffness of multiple-inclined self-tapping screw connections. These results would facilitate the design of large scale connections with long rows of self-tapping screw fasteners, such as may be used for mass timber shear wall connections or splice joints for long-span timber beams.
