Tensile and compressive contributions of fibres in peat
(ASCE: Reston, VA, USA, 2017) -
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 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 ... -
The development of a Fibre Bragg Grating river scour sensor utilizing vortex flow
(2023)The ability to effectively manage the deterioration of a network wide bridge stock condition from year on year is vital for the effective use of finite resources while maintaining public safety. The leading cause of bridge ... -
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 effect of geotechnical uncertainty on the preliminary design of large diameter monopiles
(2023)The offshore wind industry has evolved over the past decade with significant technological advances. These have been driven by the need for offshore wind energy to provide cost-competitive renewable energy. The economics ... -
The effect of prestress force magnitude and eccentricity on natural bending frequencies of prestressed concrete structures
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2016)The effect of prestress force magnitude on the natural bending frequencies of prestressed concrete structures is something widely debated in literature to date. It has major implications for the dynamic design and accurate ... -
The future of Irish access transport : investigation, modelling and appraisal
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)This thesis aims to examine in detail a variety of possible strategies for the development of the Irish access transport system. The Irish access transport system is considered as being the system (passenger and freight) ... -
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 hydrology and hydroecology of turloughs
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2011) -
The impact of local fatigue damage on bridge performance
(2023)Fatigue is one of the main failure mechanisms for steel bridges and theoretically puts restrictions or limitations on their continued use. However, bridges are structures with redundancy to various extents. The appearance ... -
The influence of lubricant slurries on skin friction resistance in pipe jacking
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)The use of bentonite and polymer slurries as lubricants to reduce jacking force has long been established practice in pipe jacking and microtunnelling, with reductions in the skin frictional resistance component of jacking ... -
The influence of particle size on the nature and transport of sediments and associated pollutants in urban stormwater drainage
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)The sediment and pollutant load transported by pipe and gully stormwater drainage systems was investigated through field sampling of a number of urban catchments. Stormwater runoff from a residential catchment was monitored ... -
The method for structural reliability analysis considering the first three moments as interval variables
(2023)In the traditional structural reliability method, the first three statistical moments of random variable are used to describe its uncertainty. But in practical engineering, due to the lack of statistical data, it is difficult ... -
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 ... -
The NARX neural network time series prediction technique and highly efficient reliability analysis method
(2023)The reliability analysis theory represented by the stochastic simulation method requires repeated deterministic structural response analysis, which undoubtedly consumes a large amount of computational cost; meanwhile, the ... -
