(University of Waterloo, 2022-08-23)Mineral dissolution or dissolution mining is a technology for underground mineral extraction. The space developed after the mining may be a desirable reservoir for the storage of natural gas and hydrocarbons or compressed ... -
Strength of Cold-Formed Steel Jamb Stud-To-Track Connections
(University of Waterloo, 2008-05-22)Cold-formed steel structural members are used extensively in building construction, with a common application being wind load bearing steel studs. The studs frame into horizontal steel track members at the top and bottom ... -
Strengthening of Wooden Cross arms in 230 kV Transmission Structures Using Glass Fibre Reinforced Polymer (GFRP) Wrap
(University of Waterloo, 2008-08-26)There are approximately 6000 Gulfport-type wood structures used to support 1600 km of 230 kV electrical transmission lines in Ontario. An unexpected structural failure caused by wood deterioration has been recognized as a ... -
Stress Intensity Factor for a Crack Embedded in an Infinite Matrix under the Assumption of Plane Micropolar Elasticity
(University of Waterloo, 2016-09-27)In last few decades, studies on defining mechanical behaviour of materials with significant microstructure have increased drastically. This is due to the lack of compatibility between the experimental data of mechanical ... -
Stress intensity factors for elliptical and semi-elliptical cracks subjected to an arbitrary mode l loading
(University of Waterloo, 2010-05-17)Fatigue durability, damage tolerance and strength evaluations of cracked structural components require accurate determination of stress intensity factors (SIF). Most practical crack configurations are embedded and surface ... -
A Structural and Economic Evaluation of Perpetual Pavements: A Canadian Perspective
(University of Waterloo, 2013-01-25)Perpetual pavement design philosophy provides a long-life pavement design alternative. The ability of a pavement design to perform as long-life pavement is subjected to several technical constraints. Throughout the past ... -
Structural Behaviour of Lapped Cold-Formed Steel Z-Shaped Purlin Connections with Vertical Slotted Holes
(University of Waterloo, 2014-05-13)Lapped joints of cold-formed steel (CFS) Z-shaped purlins are extensively used in metal building roof systems. The research that has been carried out so far for these lapped connections is primarily focused on connections ... -
Structural Behaviour of Mechanical Connections in Weld-Free Modular Aluminum Bridge Decks
(University of Waterloo, 2021-01-13)This research was done in collaboration with MAADI Group Inc. who designs and fabricates aluminum bridges. Aluminum in bridge engineering is effective since it is a lightweight and highly corrosion-resistant material. MAADI ... -
Structural Performance Evaluation of Interlocking Concrete Pavement Crosswalk Designs
(University of Waterloo, 2008-12-22)Interlocking Concrete Pavements (ICP) have been successfully used in many pavement applications all across the world. ICP design and analysis methods, construction practices and materials specifications have been developed. ... -
Studies on Nonlinear and Dynamic Soil Structure Interaction
(University of Waterloo, 2023-07-21)High-speed trains, excessive loads in moving trucks, and vibrating machines on foundations on soft ground can generate significant vibration and deformation in the subgrade (soil). Better understanding and realistic analysis ... -
A Study of Fouling on Ceramic Ultrafiltration Membranes by Model Solutions and Natural Waters
(University of Waterloo, 2013-06-19)Over the last decade polymeric membranes have emerged as an economically viable treatment option to produce drinking water. Due to higher capital costs, the use of ceramic membranes has generally been limited to industrial ... -
