Evacuations and Resilience Hubs: Preparing Edmonton and Canadian Cities for Extreme Events and Climate Change

This research project to enhance evacuation planning and resilience hub design in Edmonton will be completed through a partnership between the University of Alberta, Alberta Ecotrust Foundation, the City of Edmonton, and Mitacs. The graduate student interns will complete and guide research tasks related to data collection (e.g., survey and focus groups), data analysis, and research dissemination.

Assessment of Drag Force on Piles Subjected to Service Loads Adjacent to MSE Walls

A large portion of the infrastructures, including bridges in Manitoba, are constructed on problematic alluvial soils such as soft clays. One of the concerns related to the piled foundation bridges is downdrag which is a downward movement of the soil relative to the pile. Drag force is an additional axial force imposed on the pile due to downdrag. Underestimating this force may have detrimental impacts, including excessive settlement or even failure of structures.

Geotechnical performance of field-scale cross-laminated timber basement walls in cohesive soils

Basement walls are traditionally built with reinforced concrete in Canada. However, concrete may not perform adequately in the long term and concrete has a huge carbon footprint – more than 8% of global man-made CO2 emission comes from the cement industry. The research project is aimed at timber panel walls, a sustainable material, to replace traditional concrete in the basement construction. The research will primarily be carried out on an existing large-scale experimental timber basement wall on the university campus.

Evaluation of mechanical performance and in-situ health monitoring using destructive and non-destructive testing of cellulosic fiber reinforced cement composites

Today, construction activities have resulted in the depletion of vast amounts of non-renewable resources that cause climate change which is one of the most pressing environmental challenges of our day. The construction industry is a major source of greenhouse gas emissions globally. Sustainable construction is now mainstream, necessitating the investigation of environmentally friendly construction materials like cellulosic fibers. One of the potential applications of cellulose fibers is in development of cement-based composites.

Test-based Fracture Criteria for Pipeline Steels

Steel pipelines as key Canadian infrastructure are often exposed to various geological and environmental conditions that cause defects such as cracks, dents, and gouges in the pipe wall, which can lead to pipe fracture in pipelines, compromising the entire pipeline's functionality and resulting in significant economic losses, environmental issues or even fatalities. There are several methods to predict the fracture capacity, including experimental testing, analytical approaches, and advanced numerical methods.

Data Driven Transit Signal Priority Reliability Analysis

This study will analyse Calgary Transit’s bus operations on The City’s road network. Intersections and road segments will be categorized based on Level of Service (LOS) based performance indicators such as bus travel time and schedule adherence. The outcomes of the analysis will indicate whether a particular intersection needs transit signal priority (TSP) to improve its LOS. Intersections will be ranked then from least critical to most critical to aid in identifying intersections vulnerable to severe delay at the network level.

Development Of An AI-Based Maintenance Management Model To Reduce Energy Consumption In Existing Buildings

The main focus of this project is to maintain energy-efficient components and assets in existing buildings. Artificial Intelligence (AI) will be applied first to predict the building's components' future energy consumption and health conditions. Then, by having these data, a novel maintenance management and energy management optimization model will be created to perform the correct maintenance tasks and activities at the right time to reduce the maintenance costs and energy consumption.

Decision-making for Sustainable Buildings

To contribute to society’s decarbonization goals, the Architecture, Engineering, and Construction (AEC) industry must rapidly transition to low-carbon buildings. Low carbon construction materials and other building technologies are contributing to this decarbonization, but the rate of change for this transition remains low.

Effective concrete mixes for Saskatchewan side walks using locally available pop-out prone aggregates

A disturbing number of aggregate pop-out cases have recently been observed in newly poured concrete throughout the City of Saskatoon. A “pop-out” is a small, often cone-shaped void in a horizontal concrete surface left after a near-surface aggregate particle has fractured. Aggregate pop-outs can accelerate the deterioration of concrete sidewalks and can result in safety hazards to pedestrians and increased maintenance costs. Every year, the City of Saskatoon removes and replaces deteriorated sidewalk panels throughout the city.

Behaviour and Design of Direct-Formed Hollow Structural Sections

This research will focus on direct-formed square and rectangular hollow sections (collectively referred to as RHS hereinafter) under combined compression and bending. The effects of the novel direct-forming approach on the beam-column behaviour of RHS will be quantified via experimental testing. The beam-column testing program will include RHS with material nominal yield strengths of 350 and 690 MPa. A finite element (FE) study will be performed with models developed using the measured residual stresses, strength properties and geometric imperfections in direct-formed RHS.
