  • Mechanical Properties and Slope Stability of Dewatered Digested Sewage Sludge 

    O'Kelly, Brendan C. (M.Eng.Sc. thesis (Supervisor Dr. T.F. Widdis; Extern Prof. A. Coul), University College Dublin, University 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 ...
  • Experimental and theoretical investigations of pile and penetrometer installation in clay 

    Gill, David R. (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 ...
  • Sleeved concrete cylinders subject to hard impact 

    Prichard, Sarah J. (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 ...
  • Linear and non-linear spectral analysis of offshore lattice structures 

    Hartnett, Michael (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 ...
  • Development of a New Apparatus for Hollow Cylinder Testing 

    O'Kelly, Brendan C. (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 ...
  • The one-dimensional compression of fibrous peat and other organic soils 

    O'Loughlin, Conleth (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2001)
  • On-line monitoring of ambient hydrocarbon concentrations 

    Marnane, Ian Sean (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 ...
  • Monitoring and prediction of traffic-related urban air pollution 

    Keating, Dawn-Marie (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 ...
  • Experimental investigation on the stabilisation of Irish peat 

    Hebib, Samir (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 ...
  • Development of accurate methods of weighing trucks in motion 

    Gonzalez, Arturo (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 ...
  • Probabilistic traffic load modelling for highway bridges 

    O'Connor, Alan J. (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 ...
  • Development and application of an integrated air quality modelling system for traffic related pollution in urban areas 

    Reynolds, Anthony W. (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 ...
  • The application of genetic algorithms to civil engineering optimisation problems 

    O'Dwyer, Dermot W. (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 ...
  • Urban development : use of a neural network mode choice model 

    Heaney, Quentin R. D. (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 future of Irish access transport : investigation, modelling and appraisal 

    Whitney, Warren James (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2002)
