Stochastic Renewal Process Model for Condition-Based Maintenance
(University of Waterloo, 2009-08-31)This thesis deals with the reliability and maintenance of structures that are damaged by shocks arriving randomly in time. The degradation is modeled as a cumulative stochastic point process. Previous studies mostly adopted ... -
Stochastic Renewal Process Models for Maintenance Cost Analysis
(University of Waterloo, 2011-05-03)The maintenance cost for an engineering system is an uncertain quantity due to uncertainties associated with occurrence of failure and the time taken to restore the system. The problem of probabilistic analysis of maintenance ... -
Stochastic Renewal Process Models for Structural Reliability Analysis
(University of Waterloo, 2018-09-05)Reliability analysis in structural engineering is utilized in the initial design phase and its application continues throughout the service life of a structural system in form of maintenance planning and optimization. ... -
Stochastic Stability of Flow-Induced Vibration
(University of Waterloo, 2008-05-07)Flow-induced structural vibration is experienced in many engineering applications, such as aerospace industry and civil engineering infrastructures. One of the main mechanisms of flow-induced vibration is instability which ... -
Stochastic stability of viscoelastic systems
(University of Waterloo, 2008-05-15)Many new materials used in mechanical and structural engineering exhibit viscoelastic properties, that is, stress depends on the past time history of strain, and vice versa. Investigating the behaviour of viscoelastic ... -
Storey-Based Stability Analysis for Multi-Storey Unbraced Frames Subjected to Variable Loading
(University of Waterloo, 2008-07-23)For decades, structural engineers have been using various conventional design approaches for assessing the strength and stability of framed structures for various loads. Today, engineers are still designing without some ... -
Storey-based Stability Analysis of Unbraced Steel Frames at Ambient and Elevated Temperatures
(University of Waterloo, 2013-08-09)A fundamental task in structural stability analysis is to ensure the safety of structures throughout their operational life so as to prevent catastrophic consequences either at ambient or elevated temperatures. This thesis ... -
Storey-based stability of multi-storey steel semi-braced and unbraced frames with semi-rigid connections
(American Society of Civil Engineers, 2021-01)A simplified method is proposed for evaluating the stability of multi-storey, steel semi-braced and unbraced frames with semi-rigid connections. The proposed method decomposes a frame into individual storeys and evaluates ... -
Storey-based stability of steel frames subjected to post-earthquake fire
(Fire Technology, 2020-02)Post-earthquake fires occur after earthquakes and have commonly been encountered throughout history. The fires are particularly deadly and threaten the stability of buildings as possible structural damages caused by seismic ... -
The Storey-Based Stability of Steel Frames Subjected to Variable Gravity and Fire Loading
(University of Waterloo, 2020-02-20)The concept of storey-based stability has been developed over the past several decades, and includes powerful methods to holistically assess the structural integrity of unbraced and semi-braced steel frames. Recently, it ... -
Storey-based stability of unbraced steel frames under piece-linear temperature distributions
(Elsevier, 2019-05-21)There are many cases where the elastic modulus of a structural member will vary longitudinally, such as when a steel column is heated by fire. In such a case, the fire can compromise the integrity of the structural frame. ... -
Strategic Total Highway Asset Management
(University of Waterloo, 2013-12-10)The last decade has seen significant developments in highway asset management. A key component to successful asset management is long-term network investment planning. In order to successfully manage a significant quantity ... -
Strategically Coupled Inertial Flow and Interfaced Evolution (SCI-FIE) Models for Dissolution Mining
(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 ... -
