There is an increasing level of confusion in the industry with regards to the proper identification, use and specification of Pneumatically Applied Concrete (PAC). Indeed, it appears that many job-sites may have, over the last few years, allowed the use of Low Velocity Sprayed Mortar (LVSM) in situations where it was not appropriate, and where shotcrete would have better met the technical requirements of the specifications. No technical documentation and information are available to demonstrate if LVSM is adequate for (structural) repair applications.
Autonomous data collection on construction sites has increasing potential to replace manual surveying methods, which are expensive, non-scalable, and potentially dangerous for the workers involved. In the proposed research the intern will work with industry partners Veerum and Clearpath Robotics to advance the technology which is needed to conduct autonomous data collection on large construction projects using mobile vehicles.
The primary objective of this project is to develop and test an innovation feedback platform and methodology that will help the Canadian construction industry overcome significant, industry-wide barriers to innovative uses of wood, and become confident in embracing new ideas, products and processes, thereby advancing the uptake of innovative timber solutions at home and abroad.
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.
The proposed projects 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.
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.
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 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.
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.
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.
