Interface Management for Complex Capital Projects
(University of Waterloo, 2014-05-21)In recent years, Interface Management (IM) practices have been emerging to address the challenges of managing complex capital projects. These challenges include the added complexity and scale of these projects, globalization, ... -
An Internal Benchmarking and Metrics (BM&M) Model for Industrial Construction Enterprise to Understand the Impact of Practices Implementation Level on Construction Productivity
(University of Waterloo, 2014-05-14)Construction productivity improvement is a key concern for construction companies and the industry. Productivity in construction is a complex issue because: (1) it is influenced by multiple factors interactively; and (2) ... -
The Introduction of Crack Opening Stress Modeling into Strain-Life and Small Crack Growth Fatigue Analysis
(University of Waterloo, 2011-01-17)The work in this thesis is concerned with the mechanics of the initiation and growth of small fatigue cracks from notches under service load histories. Fatigue life estimates for components subjected to variable amplitude ... -
An Inverse Finite Element Approach for Identifying Forces in Biological Tissues
(University of Waterloo, 2009-10-01)For centuries physicians, scientists, engineers, mathematicians, and many others have been asking: 'what are the forces that drive tissues in an embryo to their final geometric forms?' At the tissue and whole embryo level, ... -
Investigating and Developing Fatigue-Healing Characterization of Asphalt Materials
(University of Waterloo, 2023-04-25)Canada’s aging highway network, consisting of over 1.1 million kilometres of roads, is a vital component in ensuring the safe and reliable day-to-day movement of people and goods. Flexible asphalt pavements experience ... -
Investigating Solutions for Self-Healing and Crack Mitigation of Flexible Pavement Materials
(University of Waterloo, 2023-01-23)In Canada, cracking is the most common deterioration mode of flexible pavements that occurs for different reasons such as traffic loading, and low temperature. Moreover, the propagation of cracks can be accelerated by the ... -
Investigating the Behaviour of Short-Span FRP-Reinforced Glulam Beams
(University of Waterloo, 2022-07-20)The broader availability of engineered wood products has generated a resurgence of wood used as a construction material over the past few decades. To further promote the use of timber, a solution aimed at increasing ... -
Investigating the Corrosion Behaviour of Carbon Black Steel Rebar in Ordinary and Limestone Cements With and Without Blast Furnace Slag
(University of Waterloo, 2022-09-30)Over the years, strange climate patterns have evolved over the globe, raising flags for concerns on the effects of global warming. Cement production contributes to 8% of the global carbon dioxide emissions. Without regards ... -
Investigating the effects of glass-fibre-reinforced polymer fabrics and bars on the flexural behaviour of sawn timber and glulam beams
