Bidirectional seismic site response analysis of granular soil deposits

Seismic response analysis are evaluations that aim to capture how the geological and geotechnical properties of soil deposits at a particular site affect earthquake motions at ground level. Commonly, this type of analysis is performed by assuming the soil layers are horizontal and that the earthquake motion travels in only one direction. However, in reality soil layers are heterogeneous and earthquake motions travel in three directions: two horizontals and one vertical. This combined effect is known as multidirectional loading.

Structural Health Monitoring using Unmanned Aerial Vehicles (Drones) for Asset Management

The proposed project’s main objective is to solve the complex and very important problem currently being faced by almost all the infrastructure owners. At present the inspection is mostly confined to visual means, which is inadequate and also not reliable due to which, many inaccessible areas of an infrastructure could not be inspected. The solution to this problem lies in providing UAV based and other non-contact assessment techniques at a reduced cost.

Investigation of Wood I-joists for Floor Applications in Mid-rise Wood Construction

PinkWood Ltd of Calgary is the largest wood I-joist producer in Western Canada. To-date it has been supplying primarily to the low-rise residential construction market. With the increased interest in mid-rise wood buildings up to 6 storeys, PinkWood is interested in expanding into this market segment. Penetrating into this non-traditional market segment will require the development of research information that addresses the concerns of build designers. In this project the three technical concerns are floor diaphragm action, vertical shrinkage of building and floor vibration performance.

Influence of base rigidity on the load-carrying capacity of loadbearing masonry walls

Design of loadbearing, out-of-plane (OOP), tall masonry walls tends to have stringent limits related to their buckling stability and the scarcity of research on their structural reliability. This currently puts the masonry industry at a disadvantage as a construction alternative compared to other structural options. The proposed research investigates the strength of tall masonry walls against lateral loads, considering the influence of base rigidity. Current design practice does not recognize the influence of actual support conditions in estimating the load capacity of slender masonry walls.

An Agile monitoring tool integrating risk, safety, and digital data infrastructure management

An innovative tool is proposed to integrate agile risk, alert, team, safety, and digital data infrastructure management into a Micro Engineering Tech Inc. (METI) current structural health monitoring system (SHM), mobile mapping system (MMS), and building information modeling (BIM) that will be called Agile Monitoring Tool. Agile Monitoring Tool includes a comprehensive project management software (CPMS) package that consists of three systems as follows. First is an SHM; the structure health monitoring development was originally part of a past successful R&D project. Second is a MMS.

Performance-Based Seismic Assessment of Irregular Bridges

The current project is designed to assess the level of damage that a realistic irregular bridge will undergo after the occurrence of an earthquake. This study encourages an improved understanding of post-seismic return to service and repair of an irregular bridge. A more sophisticated approach will be used to analyze the complex vibrations of the bridge in response to a seismic excitation and to simulate the progressive collapse of the bridge during an earthquake.

Detailed Analysis of the forces acting on a high-speed full-scale elevator

The industry partner of this project has an elevator modernization project that includes increasing the current speeds of their elevators by more than 30%. However, increase in speed is usually associated with increase in aerodynamic and lateral forces on the elevator cars, which can negatively affect ride quality and noise levels. The objective of this study is to examine the forces involved, and determine if the speed increases are within the Elevator Modernization Specification provided by industry experts.

Optimizing rheological and mechanical properties of ultra-high performance glass concrete (UHPGC) for different infrastructure applications

A new type of ecologic ultra-High-performance glass concrete (UHPGC) has been developed at University of Sherbrooke through the use of waste glass materials of different particle-size distributions derived from glass culets. The developed UHPGC proved to give several technological, economical, and environmental advantages compared to the conventional ultra-high-performance concrete (UHPC). Producing UHPGC mixtures fitting the requirements of infrastructure market has not yet been investigated.

Probabilistic Life Cycle Analysis of Alternative Reinforcement Products in the Design of Concrete Structures — Phase One: Laboratory Durability Testing

Corrosion of internal reinforcement of concrete bridges represents a significant issue. Due to a presence of deicing salts, cycles of freezing and thawing, sustained and repetitive loads, the concrete loses its ability to protect the internal reinforcement. Unprotected reinforcement starts to corrode sooner than anticipated and, therefore, reduces the bridge service life. To avoid shortening of the service life, and safe cost of maintenance, several types of advanced corrosion resistant materials have been developed.

Analysis and Optimization for Industrial Safety and Efficiency

Irwin's Industrial Safety is a leading provider of safety consulting, safety training, and safety operations management. Over the last 4 years, Irwin’s Safety has compiled data on project safety and efficiency over a wide scope of projects. Moving forward, Irwin’s Safety seeks research into how this data can best be analyzed, visualized, and used to optimize future projects. Before data can be analyzed, data scripting will be applied to transform the data into a suitable format.
