Interactions, mechanisms and impact of future coastal urban flooding. A case study of Cork city
(Hydrology Ireland, 2020-11-17)In coastal floodplains, high river flows and high coastal water levels can result in extensive flooding. Mechanisms of flooding play a crucial role in flood characteristics with distinctive differences in flood wave ... -
Application of water quality index models to an Irish estuary
(Civil Engineering Research Association of Ireland (CERAI), 2020-08-27)The paper investigates the application of different Water Quality Index (WQI) models for to estuarine waters. WQI models are aggregation based mathematical models that convert extensive water quality data into a single ... -
Assessment of water quality using Water Quality Index (WQI) models and advanced geostatistical technique
(Civil Engineering Research Association of Ireland (CERAI), 2020-08-27)Water quality index (WQI) models are popular tools to evaluate the quality of water; as such they have been developed and used by many agencies worldwide. However, the WQI model may generate excessive uncertainties in ... -
A novel ROM methodology to support the estimation of the energy savings under the Measurement and Verification protocol
(National University of Ireland Galway, 2020-09-21)This paper presents a novel Reduced Order grey box Model (ROM) methodology, based on a ResistorCapacitor (RC) network, which supports the creation of the baseline energy consumption and the estimation of energy savings ... -
Recovered wood as raw material for structural timber products. Characteristics, situation and study cases: Ireland and Spain
(International Society of Wood Science and Technology (SWST), 2020-07-12)The circular economy is an efficient system to reuse materials reducing the amount of waste generated. In order to implement it in the timber sector, the InFutUReWood (Innovative Design for the Future Use and Reuse of ... -
Characterisation of Irish-grown Scots pine timber for structural applications
(National University of Ireland Galway, 2020-08-27)There is very little knowledge on the timber quality of the native Scots pine grown in Ireland, and its potential to produce timber for structural applications. This paper studied the mechanical performance in tension and ... -
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 ... -
Irish timber - characterisation, potential and innovation
(Civil Engineering Research Association of Ireland (CERAI), 2014-09-28)In order to increase the utilisation of Irish timber in construction and novel engineered wood products, the mechanical and physical properties of the material must be established. For timber products used for structural ... -
Mechano-sorptive creep in reinforced glulam
(National University of Ireland Galway, 2018-08-20)An investigation was carried out to examine the effect of reinforcement on the creep behaviour of FRP reinforced timber elements in a controlled variable climate. Creep is accelerated by moisture variations due to a ... -
Reinforcement of timber elements in compression perpendicular to the grain using compressed wood dowels
(National University of Ireland Galway, 2020-08-27)ABSTRACT: In the past decade, there has been an increased focus on the environmental impacts of construction and a movement towards more sustainable construction products. Timber is one such sustainable product that can ... -
Vortex drop shaft structures: state-of-the-art and future trends
(International Association for Hydro-Environment Engineering and Research (IAHR), 2019-09-01)Vortex drop shaft structures have played a critical role in hydraulic engineering; from one of their first applications in hydroelectric energy dissipation in the 1940s, to numerous contemporary installations throughout modern ... -
Mechanical properties estimation by non-destructive testing of Irish hardwood round timber from thinnings for construction purposes
(Department of Forestry Policy and Economics, University of Sopron, Hungary, 2018-10-25)Thinning involves the removal of competitors of high quality trees, and trees for extraction racks, all to favour the growth of the selected trees. Many felled trees are small-diameter and in Ireland hardwood thinnings are ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
