The thermo-hygrometric properties of multi-purpose historic buildings
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)The concept of sustainability is a multi-faceted one, with environmental, social and economic aspects all requiring consideration when assessing the sustainability at a micro or macro scale. Accordingly, when considering ... -
An 'Urban Spacebook' : re-mapping the city with mobility practices and experiences
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)This thesis argues that urban sustainability cannot be reached without city inhabitants becoming more connected and engaged with their city and participating (inter)actively in planning their environments. It acknowledges ... -
Model studies on monopile foundation systems under long-term repeated lateral loads
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)Wind energy plants, dolphins, and many other ocean engineering structures are supported on large diameter rigid monopiles. For such structures lateral loads are more critical for the design and analysis compared with the ... -
An investigation of smarter driving : emission and exposure modelling and micro simulation
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)Promoting smarter driving may be a useful initiative to reduce the negative environmental impacts of travel in the present car dominated era. Smarter driving may include efficient driving and route choice which reduces ... -
A study of the properties of lime-hemp concrete with pozzolans
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Lime-hemp concrete is a sustainable building material suitable for certain construction applications. It is a mix of a lime-based binder, hemp and water. Hydraulic lime and cement are often added to the binder to enhance ... -
Light reflectance of concrete
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)A phenomenon known as the urban heat island (UHI) effect occurs where the air and surface temperatures are hotter than in their rural surroundings (Gartland, 2008). The UHI effect is a direct result of urbanisation whereby ... -
Assessment of the marine durability of self-compacting concrete using experimental testing and probabilistic modelling
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Chloride induced corrosion is recognised as the main cause of reinforced concrete deterioration for structures located in marine environments. The primary aim of this thesis is to examine the marine durability of a number ... -
The hydrogeology and restoration of a raised bog
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The occurrence of ecological communities of conservational value on the surface of raised bog wetlands requires that specific hydrological conditions are maintained. The management of raised bogs, as active peat-forming ... -
The development of a bridge network lifecycle prediction model for the Irish network
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The main aim of this thesis was the development of a bridge network condition prediction tool for the Irish network. This has been carried out with the intention of enabling the developed module to be incorporated into ... -
Fragility analysis of steel and concrete wind turbine towers
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)As the issues of global warming and a finite supply of fossil fuel based energy gain significance, the prospects and necessity for renewable energy concepts have become both socially and economically relevant. At the ... -
A framework for the Efficiency Evaluation of Ireland's Electricity Power System using Data Envelopment Analysis (DEA)
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The complex modem Electricity Power System (EPS) is the most significant pervasive infrastructure underpinning the social, technological, and economic development of modem economies The context in which modern EPSs operate ... -
Seismic analysis of braced plan irregular structures using hybrid testing and numerical modelling
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)The seismic behaviour of concentrically braced plan irregular structures has been investigated experimentally and numerically. An experimental programme consisting of twenty-four substructured soft-RT hybrid tests of a ... -
Vacuum consolidation field test on a pseudo-fibrous peat
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)Several different ground improvement methods have been used to improve soft highly compressible organic soils such as peat. Vacuum consolidation is a ground improvement technique developed in the 1950’s, in which the ... -
Modelling of hydrological pathways in Irish cathchments
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Conceptually, the main hydrological pathways contributing to river discharge are overland flow, interflow, shallow groundwater and deep groundwater. The percentage of the river hydrograph derived from each of these pathways ... -
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 ... -
Influence on spatial variability on whole life management of reinforced concrete bridges
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2009)The number of deteriorating bridges due to chloride-induced corrosion increases annually as does the cost of inspection, maintenance, repair and where necessary replacement. Meanwhile, budgets made available to bridge ... -
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 ... -
Private wells in Ireland : a quantitative assessment of groundwater quality, consumer awareness, contamination susceptibility and human health risk
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)A doctoral research study, funded by the Environmental Protection Agency, was undertaken to examine and assess the health risks associated with private groundwater sources in Ireland. Furthermore, the potential contamination ... -
Moisture movement in concrete during drying
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2009)The prediction of moisture distribution within concrete slabs has considerable practical importance as it affects the time at which coverings can be safely applied. Moisture in concrete affects creep, shrinkage, strength ... -
