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 ... -
Eco-hydrology of Pollardstown Fen, Co. Kildare, Ireland
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2008)Calcareous fens are wetlands that accumulate peat and have alkaline groundwater as their dominant hydrologic input. This combination of environmental characteristics produces an unusual type of habitat and a large number ... -
Ecosystem services and water quality of turloughs, a form of intermittent karst wetland
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2023)Ecosystem services (ES) can be defined as the conditions and processes through which natural ecosystems sustain and fulfil human life. These can be classified as provisioning, regulating, and cultural (water and raw material ... -
Enhances design of offshore wind energy gravity based structure foundations
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)The offshore wind is set for substantial growth globally in the coming decades. The use of Gravity-based foundations (GBF), although only 3.3% of the current installed fleet is due increase to 8.4% in the coming years. To ... -
Estimating the ground deformations associated with earthworks and foundations in boulder clay
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2003)Accurate estimates of the ground deformations associated with earthworks and foundations in boulder clay necessitate the validation of an appropriate soil model within a simplified ground model. Recent advances in numerical ... -
Evaluating universal design : exploring methodologies for rating universal design qualities in buildings
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)Universal design (UD) is an approach to design that places the user at the focal point of the process, and extends the understanding of who is a user is. It is focused on redefining the aims of architectural design toward ... -
Evaluation of background concentrations of air pollutants in Ireland and the development of guidelines for local assessment
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2011)The values adopted for the background air pollutant concentrations in local air quality dispersion modelling studies have a significant effect on the accuracy of the overall result. Current practice regarding the data ... -
An evaluation of the potential impacts of traffic management strategies on air pollution, emissions and public health in Dublin.
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2019)Nowadays, air pollution is a huge threat to human health. It is responsible for 6.4 million premature deaths worldwide per year, which is 72% of the 9 million deaths per year from all types of pollution. Vulnerable groups, ... -
Examining the efficiency of autonomous vehicles in highway transport
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)This study examined the efficiency of Autonomous Vehicles (AVs) in highway transport. The study focused on the effects that AVs might have on factors associated with the adoption of AVs such as safety, traffic, cost, the ... -
Experimental and theoretical investigations of pile and penetrometer installation in clay
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2000)This thesis advances our understanding of the type of ground movements and strains that take place during installation of closed-ended piles and penetrometers in clay, with particular reference to penetrometers with flat ... -
Experimental investigation of arching in sand using a trapdoor and miniature tunnel boring machine
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)Tunnel construction inevitably causes ground movements in the surrounding soil mass, which can have a negative effect on adjacent surface and sub-surface structures in the congested urban environment. Therefore in order ... -
Experimental investigation on the stabilisation of Irish peat
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)This thesis presents the findings of a study of the behaviour of a typical Midland Irish peat when mixed with a binder. The study shows that the strength of the peat can be considerably increased by the addition of various ... -
Experimental investigations of driven pile group behaviour in Belfast soft clay
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)In 1996, a site adjacent to Kinnegar Sewage Treatment Plant, near Belfast, was made available (by the Northern Ireland Department of the Environment) to Trinity College Dublin to perform load tests on driven piles. Since ... -
Facade integrated concrete solar collectors
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)Concrete solar collectors are a type of solar thermal collector that are formed by embedding pipes within a layer of concrete that acts as the solar energy absorber. Concrete is a cheap, durable and abundant material that ... -
Field tests on single piles subjected to lateral and combined axial and lateral loads
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2003)This thesis describes the results of full-scale instrumented field studies on laterally loaded piles embedded in a layered soil. The research centred around tests on (i) 350mm square reinforced concrete piles driven through ... -
