Stress changes associated with driving pile groups in clayey silt
(National University of Ireland Galway, 2003)Measurements obtained from lateral total stress sensors located on the centre pile of a small driven pile group and pneumatic piezometers installed in the vicinity of the group are used to assess the disturbance associated ... -
Teaching value engineering as a tool for reinforcing applied creativity in a troubled AEC/FM industry: A case of Zambia
(American Society for Engineering Education (ASEE), 2003)Conventional design methods that are taught to Engineers do not always take into account the practical constraints associated with resource availability and costs. For example a proposed community self-help constructed ... -
Experimental investigation of the response of a driven pile in soft silt
(National University of Ireland Galway, 2004-12-01)The paper describes the results of field tests carried out using highly instrumented piles at a very soft estuarine clayey silt deposit at Kinnegar, Belfast. The site has been used for a number of years as a geotechnical ... -
Nutrient dynamics in Cork Harbour
(2005)Estuaries are commonly characterised by high productivity due to frequent if not continuous inputs of nutrients from domestic and industrial discharge effluents and from freshwater and marine sources. These forms of nutrient ... -
Building effectiveness communication ratios for improved building life cycle management
(International Building Performance Simulation Association (IBPSA), 2005-08-15)Many existing building energy performance assessment frameworks, quantifying and categorising buildings post occupancy, offer limited feedback on design decisions. An environment providing decision makers with pertinent ... -
A nested version of the combined hydrodynamic and water quality model, DIVAST
(2007)The present research deals with the development of a one-way nested version of the combined hydrodynamic and water quality model DIVAST (Depth Integrated Velocity and Solute Transport). Initial research has concentrated ... -
A review of remediation and control systems for the treatment of agricultural wastewater in Ireland to satisfy the requirements of the Water Framework Directive
(RIA, 2008)In Ireland, agricultural activities have been identified as major sources of nutrient input to receiving waters and it has been estimated that these activities contribute 75.3% of the nitrogen (N) and 33.4% of the phosphorus ... -
Installation of a reduced-scale pile group in silt
(IHS BRE Press, 2008)This paper presents measurements of total stress and pore pressure made during and after the installation of a reduced scale group of five piles in a soft estuarine silt. The instrumentation includes pore pressure and ... -
Measured and predicted t-z curves for a driven pile in lightly overconsolidated silt
(National University of Ireland Galway, 2008-04-03)Data from a static compression load test on a single driven pile in a lightly overconsolidated silt are presented in this paper. The pile was equipped with vibrating wire strain gauges along its length enabling its load ... -
Is geotechnical education meeting industry demands? The Irish position
(National University of Ireland Galway, 2008-06-02)This paper presents the results of a survey carried out in late 2007 to gauge how geoengineering education is perceived to meet the demands of Irish industry. The survey was internet-based and the responses provide some ... -
Observed installation effects of vibro-replacement stone columns in soft clay
(National University of Ireland Galway, 2008-09-03)The installation of vibro replacement stone columns in any soil causes significant changes to the stress regime around each probe location. In soft clays, the principal effects are caused by a cavity expansion mechanism ... -
An adaptive mesh solute transport model
(2009)An adaptive mesh solute transport model is presented. The adaptive mesh scheme is implemented in a one-way multiply nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport). The ... -
A nested hydrodynamic model incorporating flooding and drying
(2009)A one-way nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport) is introduced. The nested model allows flooding and drying of intertidal areas, a process often present in areas ... -
Flexural reinforcement of glue-laminated timber beams using prestressed FRP plates.
(NetComposites Limited, 2009-09-01)Fibre-reinforced polymer (FRP) plates have been used successfully to enhance the structural performance of glue-laminated (glulam) timber beams. Unreinforced glulams usually fail in tension in a brittle fashion. The addition ... -
Formal calibration methodology for CFD model development to support the operation of energy efficient buildings
(Texas A&M University, 2010)Computational Fluid Dynamics (CFD) is a robust tool for modelling interactions within and between fluids and solids. CFD can help understand and predict phenomena that are difficult to test experimentally leading ... -
A numerical study of factors affecting the performance of stone columns supporting rigid footings on soft clay
(Taylor and Francis, 2010)The Vibro Replacement technique is now frequently used as a means of improving the bearing capacity and settlement performance of soft cohesive soils. In this paper, a parametric study using the finite element method is ... -
Analysis of jacking force data for microtunnels in glacial till at Kilcock, Ireland
(IOS Press, 2011)Although the application of microtunnelling to pipeline construction has grown considerably in Ireland in recent times, there is very little published guidance on the jacking forces that might be expected in Irish ground ... -
Formal Calibration methodology for a CFD model of a naturally ventilated room
(2011)This paper describes a systematic methodology for the development of calibrated thermodynamic Computational Fluid Dynamics (CFD) models for controlled environments in buildings utilising wireless sensor networks. ... -
A Performance Assessment Protocol for Structured Mesh Multi-Scale Models
(2011)Nesting techniques are used to develop multi-scale models giving higher resolution and thus greater accuracy in nested domains. The assessment of model accuracy is therefore important for the successful implementation of ... -
Adaptive Mesh Multi-Scale Modelling of Tidal Hydraulics and Material Transport
(2011)Multi-scale modelling for structured meshes is achieved by nesting high resolution grids within lower resolution grids. By specifying high resolutions in areas of interest only, computational cost can be reduced. Adaptive ...
