  • 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 ...
  • Soil plasticity determination using manafi method and apparatus 

    MANAFIGHORABAEI, SEYEDMASOUD (Trinity College Dublin. School of Engineering. Discipline of Civil Structural & Environmental Eng, 2017)
    Determination of soil plasticity is of great importance in geotechnical engineering projects. Consistency of soil can be expressed in terms of Atterberg limits of soils. Liquid limit and plastic limit tests are among the ...
  • Sustainable concrete with solely recycled and by-product constituents 

    Alawais, Ahmed (Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2021)
    Humans since ancient times have explored their surrounding materials throughout experiments and accumulated experience in the practice of construction, thereby recognizing the characteristics of building materials which ...
  • Sustainable Urban Drainage Systems in Dublin : a database 

    Brady, Gerard (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2010)
  • 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 ...
  • The attenuation capacity of different subsoils receiving domestic wastewater effluent 

    Ó Súilleabháin, Cormac (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 

    Reale, Tara M. (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 earthquake-resistance of flush end-plate joints 

    Thomson, Andrew William (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 prestress force magnitude and eccentricity on natural bending frequencies of prestressed concrete structures 

    Noble, Darragh (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 

    Whitney, Warren James (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) ...
