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 ... -
Air quality monitoring and modelling at motorway and roundabout sites in Ireland
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)EU legislation requires Ireland to set ambient air quality objectives, assess the ambient air quality, gather information on ambient air quality and make it available to the public, and to maintain or improve the ambient ... -
Analysis of wheel-rail contact forces resulting from vertical track irregularity
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2007)The research that is described in this thesis is based upon the formulation and analysis of mathematical models of railway vehicle and track systems. The objective of the research carried out is to compile, and then apply, ... -
Confinement in wireball-reinforced concrete members
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)Modern codes for the earthquake-resistant design of structures rely on the dissipation of seismic energy through deformations of pre-designated plastic hinge regions. In reinforced concrete members, it is of utmost importance ... -
Consolidant treatment of Irish sandstone
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2007)The objective of this study was to assess the efficiency of consolidant treatments in improving the durability of Irish sandstones. Samples of sandstones relevant to national monuments were characterised, artificially ... -
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 ... -
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 ... -
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 ... -
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 ... -
Monitoring and prediction of traffic-related urban air pollution
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)This research project involved the investigation of urban air quality with a view to (a) adding to the limited information on the state of the atmospheric environment in Dublin, Ireland and (b) formulating a methodology ... -
Monitoring of traffic related hydrocarbon concentrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)The research completed represents an experimental investigation of atmospheric hydrocarbon concentrations in the Dublin area, of which very little reported data were previously available. There was a notable lack of ... -
Nitrate responses in groundwater under grassland dairy agriculture
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2004)A considerable body of research already exists on establishing nitrate dynamics in agricultural systems' subsoils. However, the capacity to predict rates of nitrogen arrival at the receiving environment, namely surface or ... -
Probabilistic traffic load modelling for highway bridges
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)Live load models prescribed by codes for the design and assessment of highway bridges have traditionally been based on conservative subjective assumptions regarding maximum lifetime load. Modern bridge design codes have ... -
Sleeved concrete cylinders subject to hard impact
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2000)The purpose of this thesis is to determine the response of sleeved concrete cylinders to low velocity hard impact. Previous research has shown that, when concrete is uni-axially loaded and subject to the high strain rates ... -
The application of genetic algorithms to civil engineering optimisation problems
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)Genetic algorithms are optimisation algorithms that mimic the mechanisms of natural selection. This thesis is concerned with the theoretical development of genetic algorithms and with their successful application to civil ... -
The attenuation capacity of different subsoils receiving domestic wastewater effluent
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)With the domestic wastewater effluent of approximately 400,000 dwellings in Ireland being discharged to groundwater annually and about 25% of all water supplies in the country provided by groundwater a risk of contamination ... -
The earthquake-resistance of flush end-plate joints
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)This thesis investigates the applicability of flush end-plate joints to frames in low-to-moderate seismic zones. Although a great deal of research has been carried out on the use of semi-rigid joints in frames, most of ... -
The modelling of electric vehicle driving cycles, usage patterns and an investigation of the environmental and economic impacts of electric vehicles
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The European Union has set a number of policy objectives to achieve a sustainable energy fiiture through measures to tackle climate change and to ensure energy security. Electricity as fuel for vehicle propulsion offers ... -
