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.
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.
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.
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.
Combining design and digital workflows, pre-fabrication, and automated assembly provides a rare opportunity for the AEC industry to unite three critical construction items that have traditionally been at odds with one another: Time, Cost and Quality.
The utility service providers calculate the peak demand charges based on the highest level of power consumption that a facility uses in any interval (usually 15 mins) during the billing cycle. The peak demand charges in facilities such as supermarkets could represent nearly up to 40% of the total utility bill. In supermarkets, besides the building, refrigeration systems could potentially play a major role in affecting the peak demands.
To evaluate the overall performance of the newly developed Structural Insulated Panels (SIPs) in flexure, including deflections, stiffness and ultimate capacity, an experimental program has recently been launched. The program includes transverse bending tests of a total of 18 full-sized SIPs with various configurations using a vacuum chamber. Pressure and deflections are measured during the tests and are used to determine the flexural responses of the panels. For the comprehensive test matrix, the experimental results will be analysed systematically.
On-site conditions may not precisely reflect the as-designed building information models (BIMs). Inconsistencies between design and execution can lead to cumulative risks in the construction and operation stages. This project aims to improve the reliability of schedule and quantity discrepancy detection between as-designed and as-built models by exploiting the implicit information in as-designed 4D BIM (3D + schedule) using graph representation learning. The output of this module will be a semantic-aware element-wise classification of BIM objects based on their as-built status.
Precast concrete is used in many types of structures including those serving commercial, multi-unit residential, and industrial uses. Hollow core prestressed slabs (or planks) are one type of precast concrete that is used primarily for flooring systems. These planks have advantages of being able to span long distances while being relatively thin and light when compared with cast in place concrete solutions while being economically advantageous to manufactures and builders due to their ease of production.
Reinforced concrete (RC) is widely used due to its ease of construction, accessibility of raw materials, and excellent integrity. However, severe breakdown of RC structures due to mechanical and environmental loads may result in the need for strengthening to increase functionality and extend the service life of such structures. The use of fibre-reinforced polymer (FRP) composites with external bonding (EB) through epoxy adhesive is a fast, effective, and reliable solution to increase flexural or shear strength.
