Energy transfer ratio for hydraulic pile driving hammers
(NUI Galway, 2016-08-29)The ability of hydraulic pile driving hammers to overcome energy losses during freefall enables a greater proportion of the impact energy to be transferred to the pile in comparison to diesel hammers. This percentage, ... -
Enhancing low grade sitka spruce glulam beams with bonded-in BFRP rods
(National University of Ireland Galway, 2014)The reinforcement of timber elements using fibre reinforced polymer (FRP) rods or plates is widely accepted as an effective method of increasing the stiffness of members, while at the same time reducing the variability ... -
The environmental performance of a reinforced precast concrete slab with void forming system
(2014)In some climates people spend approximately 90% of their lives indoors. Thus, it is very important to maintain healthy and comfortable conditions in buildings. The building sector is responsible for about 40% of the ... -
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. ... -
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, ... -
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 ... -
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 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. ... -
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 ... -
Galway Bay bathymetry comparison from Admiralty Chart and LiDAR datasets.
(2012)The primary objective of this paper was to test the sensitivity of numerical models to bathymetry datasets. Bathymetric datasets used were from; 1) Admiralty Charts and 2) LiDAR & Multi- Beam Echo Sounder surveys. The ... -
Generating robust algorithms for energy efficient lighting as a performance aspect of the building operational energy optimisation framework
(NUI Galway, 2016-08-29)This paper presents a part of the ongoing research in the nZEB-Retrofit project in the National University of Ireland, Galway. This research aims to optimise residential building performance by enhancing the key performance ... -
Glued-in basalt FRP rods as moment connections in box section frames
(TU Verlag Wien, 2016-08-22)This paper presents an experimental programme that investigates the application of glued-in rods as moment connections in a post and beam connection. Nine such frame corners were constructed of box sections using ... -
Heave-ho! A laboratory model of an underfloor environment incorporating pyritiferous fill
(NUI Galway, 2016)Damage to domestic dwellings in the greater Dublin area of Ireland caused by the expansion of underfloor fill material containing pyrite has become a high-profile national problem in recent years. In this paper, a novel ... -
How accurate are Energy Performance Certificates indicated energy savings of building retrofits?
(NUI Galway, 2016-08-29)With the impending nearly zero energy building (NZEB) regulations for residential new builds and retrofits for the European Union (EU) housing stock and the percentage of new buildings relative to existing buildings is ... -
Influence of connection systems on serviceability response of CLT timber flooring
