Mechanical Properties and Slope Stability of Dewatered Digested Sewage Sludge
(MEngSc thesis (Supervisor Dr. T.F. Widdis; Extern Prof. A. Coul), University College DublinUniversity College Dublin, Engineering, 1995)The necessity for economically feasible landfill operations for the safe disposal/use of municipal sludges has become of paramount importance as a result of increasing environmental requirements augmenting the quantities ... -
The stability of fully and partially embedded beam-columns in elastic Winkler foundations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 1996)The stability, in terms of the buckling load, of fully and partially embedded piles that are supported laterally along their embedded length by an elastic Winkler foundation is investigated. Exact solutions are presently ... -
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 ... -
Linear and non-linear spectral analysis of offshore lattice structures
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2000)Most of the offshore structures that are used in oil and gas exploration and production are lattice jacket structures. Until recently these structures have been sited in relatively shallow water, however, the trend now ... -
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 ... -
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 ... -
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 ... -
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 ... -
The one-dimensional compression of fibrous peat and other organic soils
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001) -
On-line monitoring of ambient hydrocarbon concentrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)The result of a comprehensive set of hydrocarbon measurements undertaken at an urban roadside, rural and industrial site in Ireland are presented. Very little reported data on ambient hydrocarbon measurements were ... -
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 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 ... -
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 ... -
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) ... -
Urban development : use of a neural network mode choice model
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)It is a requirement of the EU that member states undertake the development of urban transport in a sustainable manner. According to the EU the key elements in a sustainable strategy are: -- reduction of the adverse impact ... -
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 ... -
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 ...
