Operational And Embodied Energy Analysis Of 8 Single-Occupant Dwellings Retrofit To Nzeb Standard, Richard O'Hegarty, Shane Colclough, Oliver Kinnane, Donal Lennon, Etienne Rieux
Civil Engineering Research in Ireland 2020
In line with the Energy Performance of Buildings Directive, Irish dwellings are being retrofit to near Zero Energy Building (nZEB) standards - with a number of the deep energy retrofits classified as A-rated. As a result of the low operational energy, the embodied energy share of an nZEB's life cycle energy is significantly increased. Therefore, to obtain a holistic picture of the change in energy profile of buildings, the embodied energy of the material added to achieve that low performance should also be taken into account. This paper presents results from a case study of 8 single-occupant terrace bungalows retrofit …
Loading On Long Span Bridges In Heavily Trafficked Areas, Michael Quilligan, Eugene O'Brien
Loading On Long Span Bridges In Heavily Trafficked Areas, Michael Quilligan, Eugene O'Brien
Civil Engineering Research in Ireland 2020
The critical traffic loading condition for long-span bridges is congestion when vehicles may be closely spaced together. Data on very high traffic flows is limited however, as induction loops which are typically used to collect traffic data, are ineffective when traffic flow breaks down. A number of long span bridges are located in areas of high traffic with periods of recurring congestion occurring daily. While the inter-vehicle gap distances are greater than those occurring during non-recurring full stop accident type events, the high frequency of the recurring congestion events can increase the probability of a critical load case occurring.
A Numerical Study Of The Effect Of Wind Barriers On Traffic And The Bridge Deck, Yuxiang Zhang, Philip Cardiff, Jennifer Keenahan
A Numerical Study Of The Effect Of Wind Barriers On Traffic And The Bridge Deck, Yuxiang Zhang, Philip Cardiff, Jennifer Keenahan
Civil Engineering Research in Ireland 2020
Wind actions can have a great impact on both bridges and traffic on bridges. However, structures designed to shelter the traffic from wind can influence the aerodynamic performance of the bridge deck, especially for long-span bridges. This study compares the effect of non-perforated walls and perforated walls used as wind barriers for traffic by conducting Computational Fluid Dynamics (CFD) simulations on three-dimensional geometries of a four-lane bridge deck. Steady-state simulations employ the Reynolds-Averaged Navier Stokes (RANS) method with the k-epsilon turbulence model and all simulations use parallel computing. An open-sourced software OpenFOAM is used.

Long-Run Traffic Simulations For Multi-Lane Road Bridges, Róisín Donnelly, Lorcan Connolly, Ilaria Bernardini
Long-Run Traffic Simulations For Multi-Lane Road Bridges, Róisín Donnelly, Lorcan Connolly, Ilaria Bernardini
Civil Engineering Research in Ireland 2020
The maintenance and repair of ageing bridges is a concern for road infrastructure managers. This issue is amplified by the increasing weights and frequency of travel of freight vehicles in recent times. In order to accurately assess the risk of damage for road bridges, it is essential to have knowledge of both historical and current bridge loading. When available, site-specific Weigh-in-Motion (WIM) data can be effective in creating representative load models for a structure. However, for cases where WIM data is not available and in cases where future damage must be predicted, it is necessary to simulate appropriate data using …
Simulation Of Traffic Loading On Long Span Bridges, Hang Zhang, Michael Quilligan
Simulation Of Traffic Loading On Long Span Bridges, Hang Zhang, Michael Quilligan
Civil Engineering Research in Ireland 2020
Existing long span load models have typically been developed using a number of conservative assumptions, and as such are more applicable to the design of new bridges rather than the assessment of existing structures. Excessive conservatism in such assumptions can lead to expensive and unnecessary interventions in existing bridges. Furthermore, existing load models do not always allow for correlations in traffic weights and vehicle positions on the bridge.

Civil Engineering Research in Ireland 2020
Tensegrity is a structural principle based on the use of isolated or contiguous pin jointed components in compression inside a net of continuous tension. Although the concept has been studied for many decades, relatively few examples of tensegrity structures have been used for civil engineering purposes.
Reinforcement Of Timber Elements In Compression Perpendicular To The Grain Using Compressed Wood Dowels, Michael Conway, Conan O'Ceallaigh, Sameer Mehra, Annette M. Harte
Reinforcement Of Timber Elements In Compression Perpendicular To The Grain Using Compressed Wood Dowels, Michael Conway, Conan O'Ceallaigh, Sameer Mehra, Annette M. Harte
Civil Engineering Research in Ireland 2020
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 achieve these environmental targets but, while timber has a high strength-to-weight ratio parallel to the grain, it demonstrates poor strength perpendicular to the grain. As a result, stress perpendicular to the grain is an important factor in the design of timber structures, especially in areas of concentrated loading, such as supports. This paper describes a study, which examines the use of compressed wood dowels as a sustainable alternative …
An Evaluation Of Design Issues Identified During Reviews Of Structural Designs Of Buildings From 2015 To 2020, Patrick Crean, Richard Osborne
An Evaluation Of Design Issues Identified During Reviews Of Structural Designs Of Buildings From 2015 To 2020, Patrick Crean, Richard Osborne
Civil Engineering Research in Ireland 2020
A recent study on failures of structures in Ireland indicated that approximately 40% could be apportioned to designer error. A 2019 report into recent structural cracking of a high-rise building in Sydney Australia recommended that Independent third party checking by a Chartered Engineer should be a requirement on all major projects prior to construction. The report also stated that the critical elements of the design on these projects should be identified. It is obvious that a certain percentage of buildings constructed each year contain design flaws and only a small proportion of these ever result in a failure. However there …
A Review Of The Engineering Constraints And Project Management Challenges Involved In Utilising Scot’S Church As A Heritage Asset Through Responsible Adaptive Reuse And Conservation Strategies, Óisín Smith
Civil Engineering Research in Ireland 2020
In the field of structural building, there has been a rising popularity in adaptive reuse of older structures, which stems from a variety of stimuli. Apart from preserving built heritage, providing old buildings with new functions promotes sustainability while preventing and containing urban sprawl. Target 11.4 of the United Nation’s Sustainable Development Goals Agenda 2030 explicitly outlines that “more efforts to protect and safeguard the world’s cultural and natural heritage” are required. In order to valorise and regenerate obsolescent structures, intervention is often required. The dissertation provides a comprehensive overview of conservation engineering and demonstrates the importance of an engineer’s …
Potential Of A Low-Calcium Fly Ash (Fa) For The Production Of Alkali-Activated Materials., Omar Alelweet, Sara Pavia
Potential Of A Low-Calcium Fly Ash (Fa) For The Production Of Alkali-Activated Materials., Omar Alelweet, Sara Pavia
Civil Engineering Research in Ireland 2020
Coal-FA from power stations is an industrial waste abundantly produced in the world. FA can be used as a silicate precursor, and activated with an alkali-metal source to produce alkali-activated materials (AAMs). AAMs are more sustainable than other traditional products, as the use of waste for their production, reduces carbon emissions, and raw materials and energy consumption. This paper studies the properties, composition and reactivity of an Irish FA to establish its potential for the production of AAMs. The results clearly evidenced that the FA is reactive. It is ultrafine, it has a high specific surface area and is partially …
Durability And Sustainability Of Pavement Quality Concrete In Airfields, Aidan Fogarty, Mark Richardson
Durability And Sustainability Of Pavement Quality Concrete In Airfields, Aidan Fogarty, Mark Richardson
Civil Engineering Research in Ireland 2020
Direct emissions from the aviation industry accounts for 2% of global emissions. If global aviation was a country it would be in the top 10 emitters. The International Civil Aviation Organization (ICAO) forecasts that emissions could grow by a further 300-700% by 2050. In 2010 global cement manufacture released 3270 million metric tonnes of CO2 into our atmosphere. In 2020 that amount is estimated to be 4370 million metric tonnes of CO2. This will account for around 8% of global CO2. Replacing Portland cement with 70% GGBS in concrete reduces the carbon footprint associated with the cement content in concrete. …
Preliminary Investigation On The Use Of Dolomitic Quarry By-Product Powders In Grout For Self-Compacting Concrete Applications, Ahmed Abdalqader, Katrina Wilson, Neil Thornton, Kieran Mchugh, Mohammed Sonebi, Su Taylor
Preliminary Investigation On The Use Of Dolomitic Quarry By-Product Powders In Grout For Self-Compacting Concrete Applications, Ahmed Abdalqader, Katrina Wilson, Neil Thornton, Kieran Mchugh, Mohammed Sonebi, Su Taylor
Civil Engineering Research in Ireland 2020
Self-compacting concrete (SCC) flows under its own weight without requiring external vibration for compaction. This is very useful in applications where normal vibrated concrete cannot be used such as narrow forms and reinforcement congested members. To attain the self-compacting property, it is required that the concrete have adequate viscosity, high deformability and high resistance to segregation. This is can be achieved by adding mineral admixtures (fillers) and/or viscosity modifying agents (VMAs). The former is the main practice in Europe and processed limestone powder is the most commonly used filler in the production of SCC. However, the quarrying process of the …

Maximising The Potential Use Of Ground Granulated Blast-Furnace Slag (Ggbs) In Cement: An Irish Investigation, Brendan Higgins, Michael Curran, John P. Spillane
Maximising The Potential Use Of Ground Granulated Blast-Furnace Slag (Ggbs) In Cement: An Irish Investigation, Brendan Higgins, Michael Curran, John P. Spillane
Civil Engineering Research in Ireland 2020
The production of cement is estimated to account for around 8% of carbon dioxide (CO2) emissions worldwide, and the Irish construction industry yields fifteen million tonnes of CO2 annually. Measures must be employed to reduce these emissions by incorporating less CO2 intensive admixtures such as blast-furnace slag, however, the Irish construction industry can often be resistant to change. Therefore, this study aims to investigate the potential implementation of ground granulated blast-furnace slag (GGBS) into the use of cement in Ireland, on the basis of maximisation over optimisation. This research is based on the hypothesis that if GGBS produces drastically less …

Thermodynamic Cement Hydration Modelling Using Hydcem, Niall Holmes, Denis Kelliher, Mark Tyrer
Civil Engineering Research in Ireland 2020
Thermodynamics have been successfully applied to the field of cement hydration science to predict the formation of phase assemblages and pore solution chemistry. For any cement hydration model to be accepted, it must provide accurate forecasts of which solids may form and how the cement will dissolve over time. This is particularly important for the ongoing development of new sustainable cements and understanding their hydration behaviour in service.

Computational Modelling Of Next Generation Materials For Steel Catenary Risers In The Offshore Industry, Padraic O'Donoghue, Ronan Devaney, Seán B. Leen
Civil Engineering Research in Ireland 2020
Production risers are used to conduct oil or gas from the wellhead to an offshore production facility. Due to technical challenges with flexible marine pipe at large depths, there has been a move to steel catenary risers (SCRs) in recent years, due to the availability of high strength low alloy (HSLA) steels, such as bainitic X100. HSLA steels make SCRs a viable option for deep water due to the reduction in complexity and hence cost, compared to flexible pipes. However fatigue response is an important factor in their design, particularly in the vicinity of welded connections.

Caha Tunnel Rock Repairs And Improvements Including Non-Destructive Testing, Roy Costello, Liam Duffy
Caha Tunnel Rock Repairs And Improvements Including Non-Destructive Testing, Roy Costello, Liam Duffy
Civil Engineering Research in Ireland 2020
This paper describes Caha Tunnel, a 180m long rock tunnel of siltstone and sandstone formation located along the N71 between Kenmare, Co. Kerry and Glengarriff Co. Cork. The tunnel was formed in the mid-19th century through blasting methods, thus giving it its inhomogeneous cross-sectional shape throughout and exposing the natural face of the rock. In recent years there has been numerous reports of rock falls within the tunnel which is causing uncertainty of the safety of the tunnel amongst road users. Calls for rehabilitation works are sought amongst the public to ensure the long-term safety of the tunnel is provided …
Developing A Common Framework For A Bridge Management System At National Level, Thomas Neeson, Myra Lydon, Kristopher Campbell, Nicola Ann Stevens, Adelle Marshall, Aleksander Novakovic
Developing A Common Framework For A Bridge Management System At National Level, Thomas Neeson, Myra Lydon, Kristopher Campbell, Nicola Ann Stevens, Adelle Marshall, Aleksander Novakovic
Civil Engineering Research in Ireland 2020
Transport infrastructure is directly impacted by climate change as extreme weather conditions account for 10-35% of delays/service interruptions to road and rail infrastructure. The current reactive method of maintaining bridges within these infrastructure systems results in a lack of contingency capacity and ultimately a reduced ability to adapt to uncertain future needs. To allow infrastructure providers to prepare for future events, there is a need to develop asset management systems (AMS) with embedded decision-making support which considers factors such as climate change and population growth. A National approach would enable strategic risk assessment to mitigate the consequences of climate change …

Conversion Of Legacy Inspection Data To Bridge Condition Index (Bci) To Establish Baseline Deterioration Condition History For Predictive Maintenance Models., Nicola Ann Stevens, Myra Lydon, Kristopher Campbell, Thomas Neeson, Adelle Marshall, S. E. Taylor
Civil Engineering Research in Ireland 2020
Bridge Management Systems (BMS) have been introduced across the world with the goal of aiding the decisions regarding maintenance, rehabilitation and replacement (MR&R) of bridges. Deterioration modelling is the most important part of the BMS because the ability to predict the future condition is vital as it will determine the quality of the decisions made. Markovian-based models are the most common predictive maintenance tool utilised in existing BMS, by obtaining probabilities of transition of bridge condition from one state to another based on historic bridge inspection data. Prior to the introduction of the Bridge Condition Index (BCI) the use of …

Hydraulics Of Scour In The Vicinity Of A Flexiarch Bridge, Prabuddha Sathurusinghe, Gerard Hamill, Su Taylor, Desmond Robinson
Civil Engineering Research in Ireland 2020
Floods and scour are major causes of failure of bridges and with the increase in short-duration and high intensity rainfall events the occurrence of such failures is increasing. While standard free flow scour at bridge piers is an extensively researched area, the increased scour that occurs when the upstream water level is at or above the crown of an arch bridge (pressure-flow scour) is comparatively less well studied. As the frequency and magnitudes of floods increase, more bridges may be at a higher risk of being subject to pressure-flow scour. A modern masonry arch bridge system called the ‘FlexiArch’, that …

Civil Engineering Research in Ireland 2020
As the world shifts to using renewable sources of energy, wind energy has been established as one of the leading forms of renewable energy. However, as wind turbines get increasingly larger, new challenges within the design, manufacture and operation of the turbine are presented. One such challenge is leading edge erosion on wind turbine blades. With larger wind turbine blades, tip speed begin to reach over 500 km per hour. As water droplets impact along the leading edge of the blade, rain erosion begins to occur, increasing maintenance costs and reducing the design life of the blade. In response to …

Static And Fatigue Testing Of A Full Scale Helical River Turbine Foil, Patrick Meier, William Finnegan, Patrick Cronin, James Donegan, Matthew Barrington, Le Chi Hung, Jamie Goggins
Civil Engineering Research in Ireland 2020
Despite opposition from some sectors, the imminent impact of increased hydrocarbon emissions on climate is generally accepted. Alternative energies from as many different sources must be exploited, in order to reduce the dominating market share of fossil fuels on the global energy budget. One such potential source is the capture of hydro-mechanical energy harnessed from river or tidal flows. The former is a mature industry in the case of large permanent hydroelectric plants, but smaller mobile, moored systems are of special interest in remote locations where grid connection is less widespread. Since servicing of these remote installations becomes costly, the …
Full-Scale Structural Testing Of Wind And Tidal Turbine Blades, William Finnegan, Patrick Meier, Yadong Jiang, Afrooz Kazemi Vanhari, Edward Fagan, Le Chi Hung, Jamie Goggins
