Evaluation of the mechanical behaviour of novel latticed LVL-webbed joists
(Bentham Open, 2019-01-23)The mechanical behaviour of a novel I-joist having a latticed Laminated Veneer Lumber (LVL) web is investigated. A total of 30 joists with C24 Grade flanges and latticed LVL webs were manufactured and tested to failure. ... -
An evaluation of the performance and optimization of a new wastewater treatment technology: the air suction flow-biofilm reactor
(Taylor & Francis, 2014-12-09)In this laboratory study, a novel wastewater treatment technology, the air suction flow-biofilm reactor (ASF-BR) - a sequencing batch biofilm reactor technology with a passive aeration mechanism - was investigated for its ... -
Evaluation of the structural behaviour of beam-beam connection systems using compressed wood dowels and plates
(NUI Galway, 2018-08-20)To support the transition to a bio-based society, it is preferable to substitute metallic fasteners and adhesives in timber construction with an eco-friendly alternative. Recent studies have identified compressed wood ... -
Evaluation of various turbulence models to predict indoor conditions in a naturally ventilated room
(2013)In recent years, Computational Fluid Dynamics (CFD) has become a popular tool in building simulation. However, developing reliable CFD models requires a high level of expertise in fluid dynamics and numerical techniques. ... -
Evidence of stabilised peat as a net carbon sink
(American Society of Civil Engineers, 2019-01-09)Mass stabilization, a ground improvement solution used for construction in peatlands, involves mixing suitable dry binders into the peat, increasing strength and stiffness and reducing permeability. A previous pilot study ... -
Examination of homogeneity of selected Irish pooling groups
(2010)In regional flood frequency estimation, a homogeneous pooling group of sites leads to a reduction in the error of quantile estimators which is the main aim of a regional flood frequency analysis. Examination of the homogeneity ... -
An examination of maximum legal application rates of dairy processing and associated STRUBIAS fertilising products in agriculture
(Elsevier, 2021-10-09)The dairy industry produces vast quantities of dairy processing sludge (DPS), which can be processed further to develop second generation products such as struvite, biochars and ashes (collectively known as STRUBIAS). These ... -
Experiences of dry soil mixing in organic soils
(Institution of Civil Engineers, 2012)Soil mixing, or soil stabilisation, is a method of enhancing the geotechnical properties of suitable host soil through the addition of cementitious and/or pozzolanic binders in either dry or slurry forms. In dry soil mixing, ... -
An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
(Departamento de Ingeniería en Maderas de la Universidad del Bio-Bio en Concepción, Chile, 2019)The use of fast-grown timber in the manufacture of engineered wood products is increasing; however, the fast growth rate results in a low-density timber that is susceptible to significant swelling and shrinkage deformations ... -
Experimental characterisation of the moment-rotation behaviour of beam-beam connections using compressed wood fasteners
(Elsevier, 2021-09-16)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
Experimental investigation of the moment-rotation behaviour of beam-column connections produced using compressed wood connectors
(Elsevier, 2022-04-04)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
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 ... -
Experimental investigation of the serviceability behaviour of a cross laminated timber floor
(NUI Galway, 2018-08-29)European timber design standards set out basic serviceability limit design criteria for single span, simply supported floors, but the rotational stiffness of the fixing system and two-way support possible with modern solid ... -
Factors affecting Embodied Carbon/Embodied Energy associated with ground improvements techniques for construction on peat
(NUI Galway, 2012)In addition to the traditional drivers of cost and timely programme delivery, embodied energy (EE) and embodied carbon (EC) have emerged as major considerations in all aspects (including geotechnical) of large construction ... -
Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland
(Elsevier, 2009-07)Groundwater contamination was characterised using a methodology which combines shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a statistical framework and hydro-geological techniques. Nitrate-N ... -
Field assessment of coconut-based activated carbon systems for the treatment of herbicide contamination
(Elsevier, 2023-12-03)Once released into the environment, herbicides can move through soil or surface water to streams and groundwater. Filters containing adsorbent media placed in fields may be an effective solution to herbicide loss in the ... -
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ... -
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 ... -
