The project focuses on the development of SCRC mixtures using concrete materials available in Newfoundland. The developed SCRC mixtures can be successfully used by concrete suppliers in Newfoundland, especially for the construction of marine and offshore structures, which are exposed to ice abrasion and impact loading from ships, waves, and icebergs. In addition, this kind of concrete, where it is durable in freezing and thawing, can be used effectively in cold regions.
The research undertaken through the Regenerative Neighbourhoods Project explores the ways that specific building and infrastructure projects can act as catalysts for transformational change at the neighbourhood scale with respect to sustainability objectives. It encompasses both substantive performance improvements and the changes in the project delivery processes required to achieve them.
The scope of this project is to construct a physics-based analytical model through the bond graph modeling for a reciprocating compressor. The purpose of this model is to quantify input-output relations among mechanical components involved in a compressor, particularly under normal operating conditions. Such a model, once validated and calibrated can serve as a baseline model or a template for the detection of machine health problems. Because of the details of a machine internal variables this model can provide, it can allow the root cause determination of machine faults.
Today's modern industries aim at supplying premium quality products that can offer added performance value, lower weight, less environmental impact, decreased manufacturing and maintenance costs, increased durability and safety, and eventually higher customer satisfaction and market competitiveness. To achieve these milestones, new engineered materials such as fiber-reinforced polymers are rapidly replacing traditional single materials such as steel and aluminum.
The intended research aims at bringing the design and production process of the industry partner, BONE STRUCTURE into a new level of customization, that involves effective homebuyers participation in the design of their homes, using cutting-edge computatioanl design techniques. The customization process is initiated with a layout design; roomblocks modifications, till selection of appliances and systems, via web- based, interactive interface that would engage homebuyers in a designer-customer like dialogue.
Sous la pression des exigences d’intégration future des technologies associées au Building Information Modeling (BIM) pour la production et la gestion de l’information du bâtiment, l’industrie de la construction vit une transformation radicale de ses pratiques. Le BIM oblige de briser le mode traditionnel de travail divisé entre spécialités et organisé comme une série d’activités séquentielles pour proposer une organisation du travail intégrée autour d’une plateforme unique et partagée. Ce changement oblige l’ensemble des spécialistes à revoir leurs façons de faire.
Construction companies spend significant amounts of resources on front end planning (FEP). The potential to obtain substantial benefits from a strategic implementation of front end planning practices across an entire portfolio have made the evaluation of FEP an important issue for both project leaders and scholars. The opportunity now exists to mine the constituent elements of the index based on historical project data sets to develop methods for planning proactive strategies in capital projects execution.
This postdoctoral study is an experimental investigation on the bond behaviour of externally-bonded (EB) fibre-reinforced polymer (FRP) L-shaped FRP plates to the concrete substrate. This study will be the foundation of an upcoming comprehensive study on rehabilitation of reinforced-concrete (RC) beams with L-shaped FRP plates and end-anchored FRP fabrics. Recently, EB FRP composites are increasingly used to strengthen existing RC structures. However, de-bonding of FRP fabrics or plates is still a major issue.
The deterioration of our aging underground pipe network emerges as a critical problem. Concrete pipes may be damaged due to salt attack from outside and sulfide attack from inside, hence compromising its structural integrity. Repairs for such pipes are time-consuming and expensive. A revolutionary trenchless structural rehabilitation technique is introduced. In this technique Innovative honeycomb-FRP Composite Sandwich (HCS) are used for retrofitting concrete pipes (InfinitPipe™).
L’industrie de la construction est un secteur majeur au Québec puisqu’elle représente à elle seule 13% du PIB et 1 emploi sur 20. Cependant, la réglementation qui l’encadre pose quelques difficultés. Cette réglementation date de 1968 et il s’agit de la Loi sur les relations du travail, la formation professionnelle et la gestion de la main-d’oeuvre dans l’industrie de la construction, ou loi R-20. La problématique soulevée dans cette étude est la partie de cette loi relative à la formation obligatoire pour les vingt-cinq métiers du bâtiment.
