Use of UHPC as a building material in Northern climates

In this project different UHPC mixes will be proposed and tested for mechanical and physical material properties when subjected to extreme cold temperatures. The mixes which meet the required properties and are most economical will be used for further structural wall panel testing and will be proposed to the company. The proposed concrete mix will be used to build insulated sandwich wall panel specimens and structural strength test will be conducted on them.

Characterizing and Optimizing polyurethane cementitious composite mixtures

In industrial areas like manufacturing units, logistics centers, and warehouses, floors are exposed to heavy traffic along with high mechanical loads and possible chemicals contact. This promotes the use of polymeric cementitious flooring compositions such as epoxy resin-based flooring compositions and polyurethane (PU) cementitious systems. The latter showed outstanding mechanical properties and do not suffer from the drawbacks associated with epoxy resin-based compositions. PU system is composed of two different binding systems: polyurethane (diisocyanate) binders and hydraulic binders.

Work improvement for the manual heavy structural workstations by using dynamic value stream mapping

The goal of the proposed research project is to improve the work productivity for the partner company (Ocean Steel) by identifying bottlenecks accurately in the steel fabrication workstations. This work included evaluating the current applied solutions in order to resolve the same problems encountered with Ocean Steel, which was done by conducting a literature review. However, many of the solutions that were found were not applicable to the Ocean Steel case, meaning that some improvement is required).

A Holistic Framework to Evaluate Energy Consumption of Heritage Buildings

The outcome of the proposed research on heritage buildings could benefit the industry, including EVOQ Strategies’ work as they have been involved in a number of projects on heritage buildings. Keeping the above in mind, the following general objectives are identified for the current research: - Provide a detailed overview of existing technologies as well as the opinions of experts in the field of energy performance sustainability assessment for heritage buildings. Thus, in a sense, it serves as a benchmark for different researchers looking to design their own assessment tool.

Application of Ultrasonic Guided Waves for CANDU Piping Inspection

Computer modeling and experimental testing will be conducted to examine and verify the reliability of ultrasonic guided wave techniques for detecting wall thinning and cracking in feeder pipes in CANDU nuclear reactors. Bracelets holding 8 and 16 ultrasonic transducers will be developed. These bracelets are attached to the pipe to produce guided waves which propagate along the pipe. A reflected wave is generated when guide waves encounter a defect (e.g., cracking).

Performance based design of sound wall foundation under freeze-thaw cycle effects

Presently, sound wall foundation design for steel piles is being governed by the effects of the freeze-thaw cycles. The deformations produced by the freeze-thaw cycles cause structural damage and can be seen as an important index to judge the stabilities of structures in cold regions. A very limited number of studies investigated pile design within the context of sound wall foundation, as the behavior of these foundation under the cumulative freeze-thaw deformations is yet to be characterized.

Flexural bending analysis of mycelium structural beams

The main goal of this project is to improve the sustainability of building materials. To work towards this goal, theresearch project turns towards biology as a source of inspiration for the next generation of building materials.Natural fibres (i.e. hemp, straw, agricultural residues) have great potential in the building industry, but currentlystill need to use fossil-fuel based binding agents. This project will research the capacity for mycelium as analternative binding agent for natural fibre construction materials.

Simulating the Compounding Effect of Freeze-Thaw Cycles on the Durability and Seismic Performance of Masonry Buildings

The frost deterioration caused by freeze-thaw cycles (FTC) is of great concern in masonry buildings due to its detrimental effect on durability and long-term seismic performance. Recent findings reveal a substantial reduction in mechanical properties of masonry (e.g., compressive strength) when exposed toFTC. This material damage weakens the seismic capacity of masonry walls, increasing the vulnerability of existing masonry buildings and cultural heritage.

Finite element modelling for the assessment of dented pipelines

Pipelines are extensively used across Canada and worldwide as a safe, reliable, and environmentally friendly way of transporting oil and gas. The pipelines traversing different ground conditions are sometimes subjected to minor mechanical damages from external interference. A dent is a type of mechanical damage resulting in a plastic deformation of the pipe wall. The proposed research focuses on developing a cost-effective solution for the dented pipes with an assessment of the performance of the pipes using numerical modeling.

Experimental investigation of the influence of shear connectors on the effective flange width, strength, and stiffness of CLT-glulam T-beams

The overarching aim of this research is to develop fundamental knowledge of hollowcore mass timber (HMT) panels for long floor spans currently not attainable using conventional all-wood flat-plate floor systems due to the slab spans being limited by vibration and human comfort. The feasibility of HMT panels comprised of crosslaminated timber (CLT) for top and bottom flanges, connected to glulam webs using adhesive or mechanical fasteners is investigated by evaluating the effects of key parameters on the effective flange width of CLT-glulam T-beams.
