Soil-structure interaction and design limit states for large-span Ultra-Cor steel bridges

Arched culverts are widely used nowadays as a solution for numerous roadways and railways overpassing as they are cheaper and easy to construct in comparison to conventional concrete and steel bridges. The current study involves three-dimensional numerical simulation for three full-scale field monitored large-span arched culverts (including the largest span arched culvert in the world of 32 m). The verified numerical model will then be used to investigate the impact of several parameters such as the supported soil and truck loading on performance of large span culverts.

A study on soil-pipe interaction: effects of slope grade

Transmission pipelines are the most popular and widely used medium to transport hydrocarbons (e.g., oil and gas) over long distances. Pipelines might pass through various geological and topographic conditions and therefore, pipeline routing is a critical component for successful design and regulatory approval. Due to the environmental and safety concerns or constraints imposed by the land use, pipeline routing often requires designers to allow for crossing adverse ground, e.g. steep slopes, valleys and faults.

Investigation of Low-Ductility Geogrid Reinforcement for Ground-supported Concrete Structures

Steel rebars are the dominant reinforcement elements in reinforced concrete structures due to their relatively adequate manufacturing, material property and established construction codes. In an ideal environment and under nominal loading, conventional concrete reinforcement is expected to govern the design strength based on which they are designed. However, under environmental loading conditions, such as very low or very high temperature, deterioration of the steel reinforcement is accelerated and lead to significant structural, economic and environmental losses.

Erosion studies of southern Ontario tills and St. Lawrence Valley marine clays and assessment of an extreme precipitation prediction approach

Quaternary glacial deposition has covered much of southern Ontario with tills and the Saint Lawrence Valley with marine fines. Rivers incised into these materials exhibit particular geomorphologic behavior. Civil engineering works built either in (e.g. dams, bridge piers, etc.), beside (linear infrastructure such as roads, railways, etc.) or across (e.g. bridges, etc.) such rivers must consider the erosion of these cohesive sediments. There is currently very little knowledge about the erosion of these materials.

Development of an antibacterial membrane for purification of floodwater

When floods happen, municipal water distribution systems are damaged and the residents will not have access to clean water. As a result, the will face the risk of health effects from water-born bacteria and pathogens increases. In this project, we proposed a system to purify the water stored frim flood water. This purified water can be used for drinking. This membrane based system can remove the bacteria and pathogens from water. To fabricate the membrane, we will use biopolymers and metals with antibacterial properties.

3-Dimensional Construction Printing: Materials and Robotics

This project is intended to development the technologies needed for three-dimensional (3D) printing of concrete constructions. This highly interdisciplinary research endeavor will draw on expertise in additive manufacturing, construction, materials science, and robotics to develop the key elements of 3D construction printing.

Non-destructive Testing of Backfill Strength in Support of Continuous Mining

Underground mines generate significant volumes of crushed waste rock, called tailings, but almost half of these can be returned underground and used as value-added backfill. This research uses non-destructive sensors that monitor the backfill’s strength in real time and provides operators with information needed to safely place backfill as quickly as possible. The sensors will be developed and deployed at operating mines so that they are validated under real-world operating conditions.

Synthesizing the State of Practice of On-Demand Transit in Canada

This project proposes a survey directed at transit agencies in Canada that have operated, operating, or planning to operate flexible transit, with special emphasis placed on app-based on-demand transit services. Personal interviews will be conducted with key personnel at the transit agencies, likely using phone communication. The results of the survey along with a more comprehensive review of industry reports will be summarized to highlight the key practices of flexible transit in Canada.

Assessment of indoor environmental quality in the school building

Indoor environmental quality in schools is one of the major issues that should be considered. Indoor air quality (freshness and cleanness of air inside the building) and thermal comfort (the comfortable condition when no one is feeling either too hot or too cold) in schools can have significant impact on children’s health, learning and productivity. The purpose of this research is to evaluate indoor environmental quality (indoor air quality, thermal comfort, lighting, and acoustics) in First Nation School.

Application of Data Analytics Approaches for Solvent-Assisted Bitumen Recovery Pilot Analysis

This project will develop data-driven models for production performance analysis and optimization for solvent-assisted bitumen recovery operations and related processes. Effective operations of solvent processes are crucial for improving oil production and maintaining a low solvent-to-oil ratio (SOR).
