Site investigation ... -
Design and analysis of concentrically braced steel frames under seismic loading
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The lateral resistance of many steel framed structures is provided by diagonal brace members and their connections to the frame. Although concentrically braced frames (CBFs) are common throughout international design ... -
Detection and assessment of damage in underwater marine structures using image processing based techniques
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)The monitoring of underwater structures is often beset by limited access, exorbitant costs and inherent safety issues. This thesis focuses on developing and implementing automated image processing based Non-Destructive ... -
The Detection of Infarcted Stroke Tissue via Localised Sodium Concentration Measurements: A Non-Invasive Approach
(Trinity College DublinTrinity College Dublin, 2009)Quantitative 23Na Magnetic Resonance Imaging (qNa-MRI) is a non-invasive technique which has considerable potential for measuring Tissue Sodium Concentration (TSC) changes in pathological brain tissue states such as ... -
Determination of a reduced dataset to guide forecasting of energy use in commercial buildings
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)The importance of reducing energy usage in buildings is difficult to overstate. Approximately 10% of all energy consumed in the EU and the US is used on the provision of occupant thermal comfort in commercial buildings. ... -
Development and application of an integrated air quality modelling system for traffic related pollution in urban areas
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)An Air Quality Modelling System (AQMS) has been developed for metropolitan areas in Europe and applied in Dublin. The primary objective of this AQMS is to incorporate die latest knowledge on traffic and air quality at a ... -
Development and verification of yield surfaces for I-sections
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2009)In the design of many building structures for ultimate states the use of interaction equations is quite common. Despite this there is still a need for more advanced and flexible equations which consider all forces in space. ... -
Development of a New Apparatus for Hollow Cylinder Testing
(PhD thesis, University College Dublin (Supervisor Dr. T.F. Widdis; Extern Prof. David Muir Wood)University College Dublin, Faculty of Engineering and Architecture, 2001)The Hollow Cylinder Apparatus (HCA) is the only soil test device that can facilitate independent control of both the magnitudes and directions of the principal stresses. The stress history and loading conditions at a point ... -
Development of accurate methods of weighing trucks in motion
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)The need to weigh and classify vehicles is based on the damage that large trucks cause to road infrastructure. Weigh-in-Motion (WIM) data can be used to predict future traffic volumes and weights for the planning of new ... -
Development of predictive control strategies for building climate control
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)The rapid growth in energy usage and CO2 emissions has become a critical issue for the whole world. It is noteworthy that buildings are a major contributor to global primary energy consumption. Among building services, use ... -
DEVELOPMENT OF SUSTAINABLE, ALKALI-ACTIVATED BINDERS FOR CONSTRUCTION
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2023)This work contributes to the design and production of alkali-activated materials (AAMs) of lower environmental impact than Portland cement (PC) products. AAM binders result from the reaction of an activator and a precursor. ... -
Dynamic response of Spar-type Floating Offshore Wind
Floating offshore wind turbines (FOWTs) are an alternative technology to harness the abundant wind energy in open sea areas. A FOWT structure consists of a floating platform, a mooring system, and a wind turbine structure ... -
Dynamic response of wind turbine tower assemblies
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)As wind turbine towers are composed of several flexible inter-connected components, it is important that the engineer has the ability to understand the dynamic behaviour of the system, including that of its components, in ... -
Dynamics of wind turbines including soil-structure interaction
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)This thesis investigates the dynamic response of Horizontal Axis Wind Turbines (HAWT) including Soil-Structure Interaction (SSI) effects. Multi- Degree-of-Freedom (MDOF) HAWT models are proposed for dynamic analysis using ... -
Earthquake resistant hollow and filled steel braces
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2004)The earthquake resistance of many building structures is provided by steel bracing members. Although the use of tension-only concentric bracing is common, the behaviour of these systems is not fully understood, and ... -
