An analytical approach for the prediction of single pile and pile group behaviour in clay
Sheil, Brian B.; McCabe, Bryan A. (Elsevier, 2016-02-21)In this paper, the 't-z method' is employed to describe the nonlinear behaviour of a single pile and is used to obtain simplified predictions of pile group behaviour by considering the interaction between two-piles in ... -
Appraising stone column settlement prediction methods using finite element analyses
Sexton, Brian G.; McCabe, Bryan A.; Castro, Jorge (Springer Verlag, 2014-09-26)Numerous approaches exist for the prediction of the settlement improvement offered by the vibro-replacement technique in weak or marginal soil deposits. The majority of the settlement prediction methods are based on the ... -
The assessment of embodied energy in typical reinforced concrete building structures in Ireland
Goggins, Jamie; Keane, Terasa; Kelly, Alan (2010)This paper demonstrates that by understanding how energy is consumed in the manufacturing of reinforced concrete, designers can significantly reduce the overall embodied energy of structures. Embodied energy of products ... -
Assessment of intermittently loaded woodchip and sand filters to treat dairy soiled water
Murnane, J. G.; Brennan, R. B.; Healy, Mark G. (IWA Publishing and Elsevier, 2016-07-31)Land application of dairy soiled water (DSW) is expensive relative to its nutrient replacement value. The use of aerobic filters is an effective alternative method of treatment and potentially allows the final effluent to ... -
Assessment of Tc-99 monitoring within the western Irish Sea using a numerical model
Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (Elsevier ScienceDirect, 2010-05-26)Water circulation patterns and associated material transport within a highly dynamic system such as the Irish Sea are complex phenomena. Although Tc-99 monitoring programme undertaken by the Radiological Protection Institute ... -
Biaxial loading of offshore monopiles: numerical modelling
Sheil, Brian B.; McCabe, Bryan A. (American Society of Civil Engineers, 2016-05-18)In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and ... -
Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
Troy, Shane M.; Healy, Mark G.; Kwapinski, Witold (2011)The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ... -
Creep improvement factors for vibro-replacement design
Sexton, Brian G.; Sivakumar, Vinayagamoothy; McCabe, Bryan A. (ICE Publishing, 2017-02)Although the vibro-replacement stone column technique is being deployed increasingly in soft cohesive soil deposits in which creep settlements may be significant/dominant, the majority of existing stone column settlement ... -
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads
Rodgers, Michael; Hayes, G; Healy, Mark G. (Elsevier, 2009)This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ... -
Denitrification of a nitrate-rich wastewater using various wood-based media materials
Rodgers, Michael; Mulqueen, John; Healy, Mark G. (2006)This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus ... -
Determination of flushing characteristics of the Irish Sea: A spatial approach
Dabrowski, Tomasz; Hartnett, Michael T.; Olbert, Agnieszka Indiana (Elsevier ScienceDirect, 2011-12-08)The Authors devised a novel generic approach to assessing the flushing of the Irish Sea through the determination of spatially distributed residence times and the development of flushing homogeneity curves. Results indicate ... -
Development of a nested coastal circulation model: boundary error reduction
Nash, Stephen; Hartnett, Michael (Elsevier, 2014-03)Numerical models have a valuable role to play in the sustainable management of coastal waters but accurate simulation of land/sea interactions, particularly in areas of complex coastlines, requires the use of high spatial ... -
Different depth sand filters for laboratory treatment of synthetic wastewater with concentrations close to measured septic tank effluent
Walsh, G.; Rodgers, Michael; Healy, Mark G. (2011)The objective of this study was to apply hydraulic and chemical oxygen demand (COD) loading rates at the upper limits of the design criteria for buried sand filters to test the sand filter depth design criteria. Over a ... -
Discussion: Interaction factor for large pile groups
Wang, A.D.; Wang, W.D.; Huang, M.S.; Wu, J.B.; Sheil, Brian B.; McCabe, Bryan A. (ICE Publishing, 2016-09-27)The authors present an interesting paper on the use of the interaction factor method (IFM) for settlement analysis of large pile groups. -
Effect of chemical amendments to dairy soiled water and time between application and rainfall on phosphorus and sediment losses in runoff
Serrenho, Ana; Healy, Mark G. (2012)Dairy soiled water (DSW) is a dilute, low nutrient effluent produced on Irish dairy farms through the regular washing down of milking parlours and holding areas. In Ireland, there is no closed period for the land application ... -
Effect of sawdust addition on composting of separated raw and anaerobically digested pig manure
Troy, Shane M.; Healy, Mark G. (Elsevier, 2012)Manures need the addition of carbon-rich bulking agents to conserve N during composting, which increases the cost of the composting process. The recommended proportion of manure/sawdust, based on a carbon (C):nitrogen (N) ... -
