Soil-Structure Interaction Analysis of Monopile Foundations Supporting Offshore Wind Turbines
(University of Waterloo, 2018-08-07)Monopile foundations supporting offshore wind turbines are hollow circular steel piles of diameter 4-6 m and a slenderness ratio (length/radius) of 10-12 driven into the seabed in an average water depth of 35 m. They are ... -
Spatial and Temporal Trends in Water Quality in a Mixed-Use Landscape: Agriculture vs. Urban Areas
(University of Waterloo, 2018-10-22)The eutrophication of aquatic ecosystems is a growing water quality concern as it can promote the proliferation of harmful algal blooms that have severe environmental, health, and economic impacts. In United States alone, ... -
Spatial Decision Support System for Urban Streams
(University of Waterloo, 2017-09-27)The change of land use from rural to urban tends to radically alter the implicated streams with many symptoms of the “urban stream syndrome”. The key driver of the syndrome is hydrologic change; the product of increased ... -
Stability Assessment of Salt Cavern Roof Beam for Compressed Air Energy Storage in South-Western Ontario
(University of Waterloo, 2017-10-24)Due to the intermittent nature of renewable energy sources, application of energy storage systems is an important part of the development in support of clean technologies. Compressed Air Energy Storage (CAES) plants can ... -
Stability of a Structural Column under Stochastic Axial Loading
(University of Waterloo, 2009-08-19)Columns subjected to time varying axial load may exhibit dynamic instability due to parametric resonance. This type of instability is inherent in structures; it is not due to material or geometrical imperfections, and can ... -
Stability-based fire resistance duration of unbraced steel frames
(Journal of Structural Fire Engineering, 2020)Purpose The collapse of a structure resulting from the instability of steel frames due to fire is the worst failure mode to consider in fire-structural engineering, and should be avoided. The purpose of this paper is to ... -
State of research in automatic as-built modelling
(Elsevier, 2015-04-01)Building Information Models (BIMs) are becoming the official standard in the construction industry for encoding, reusing, and exchanging information about structural assets. Automatically generating such representations ... -
The Static and Fatigue Behaviour of Through-Bolt Shear Connectors in Steel-Precast Composite Bridge Girders
(University of Waterloo, 2018-01-22)Increasing demand for the rapid and economically efficient construction of bridges has encouraged engineers to employ the use of accelerated bridge construction through modular assembly. The replacement of vehicular bridges ... -
Statistical Modeling of Fracture Toughness Data
(University of Waterloo, 2007-09-25)The fracture toughness of the zirconium alloy (Zr-2.5Nb) is an important parameter in determining the flaw tolerance for operation of pressure tubes in reactor. Fracture toughness data have been generated by performing ... -
Statistical Sample Size Determination Methods for Inspections of Engineering Systems
(University of Waterloo, 2018-12-18)A statistical sample size determination (SSD) method is designed for the maintenance of engineering components of similar structure within an overall system. The maintenance problem is defined as a sequential decision-making ... -
A Stochastic Approach to Measurement-Driven Damage Detection And Prognosis in Structural Health Monitoring
(University of Waterloo, 2017-12-08)Damage detection and prognosis are integral to asset management of critical mechanical and civil engineering infrastructure. In practice, these two aspects are often decoupled, where the former is carried out independently ... -
A Stochastic Framework for Soil-Structure Interaction and Constitutive Modelling
(University of Waterloo, 2019-08-19)A stochastic framework for soil-structure interaction and constitutive modelling is investigated in this thesis and developed to account for uncertainties in material properties and loading conditions. The development ... -
Stochastic Modeling of Deterioration in Nuclear Power Plant Components
(University of Waterloo, 2007-04-13)The risk-based life-cycle management of engineering systems in a nuclear power plant is intended to ensure safe and economically efficient operation of energy generation infrastructure over its entire service life. An ... -
