  • 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 ...
  • Development and verification of yield surfaces for I-sections 

    Shoaib, Afaq (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2009)
    In the design of many building structures for ultimate states the use of interaction equations is quite common. Despite this there is still a need for more advanced and flexible equations which consider all forces in space. ...
  • 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 ...
  • 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 ...
  • Development of predictive control strategies for building climate control 

    NAGPAL, HIMANSHU (Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)
    The rapid growth in energy usage and CO2 emissions has become a critical issue for the whole world. It is noteworthy that buildings are a major contributor to global primary energy consumption. Among building services, use ...
  • Dynamic response of Spar-type Floating Offshore Wind 

    Nguyen, Hoa Xuan
    Floating offshore wind turbines (FOWTs) are an alternative technology to harness the abundant wind energy in open sea areas. A FOWT structure consists of a floating platform, a mooring system, and a wind turbine structure ...
  • Dynamic response of wind turbine tower assemblies 

    Murtagh, Paul J (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)
    As wind turbine towers are composed of several flexible inter-connected components, it is important that the engineer has the ability to understand the dynamic behaviour of the system, including that of its components, in ...
  • Dynamics of wind turbines including soil-structure interaction 

    Harte, Michael (Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)
