Development Of Zeolitic Imidazolate Frameworks For Enhancing Post-Combustion Co2 Capture, Dustin Lee
Master's Theses
Post-combustion CO2 capture is a promising approach for complementing other strategies to mitigate climate change. Liquid absorption is currently used to capture CO2 from post-combustion flue gases. However, the high energy cost required to regenerate the liquid absorbents is a major drawback for this process. As a result, solid sorbents have been investigated extensively in recent years as alternative media to capture CO2 from flue gases. For example, metal organic frameworks (MOFs) are nanoporous materials that have high surface areas, large pore volumes, and flexible designs. A large number of MOFs, however, suffer from 1) low CO …

Cathedrals and most churches are characterised by having large internal, undivided spaces and permeable building envelopes. They are often used little, intermittently, but predictably and, in spite of the fact that they are unique in still being largely used for the purpose for which they were built many centuries ago, they are now often used for additional purposes, for which they were never designed. These uses include concerts, graduation ceremonies, filming and a host of other uses all of which require a level of thermal comfort not envisaged by the original builders. Research was undertaken by the authors into the …

Challenges And Opportunities To Deep Retrofitting Of Traditional Fabric Buildings To Achieve Nearly Zero Energy Building (Nzeb), Maria Lopez Zambrano, Paul Kenny, Jamie Goggins
Civil Engineering Research in Ireland 2020
Many of our traditional buildings are disappearing or in danger of being under utilised because they are not comfortable for modern day living and do not meet our present day needs. If a building does not have a use, inevitably it deteriorates and eventually becomes a ruin or gets demolished. It is important to retrofit these buildings, which are part of our identity and can be powerful tourist attractions even though most of them are not listed. Some owners want to apply for retrofitting schemes and grants, but they are rejected because there are no standard solutions to achieve low …

Can Deap Help Us To Predict The Energy Demand And Indoor Temperature Of Homes Before And After Renovation? A Case Study From Dublin, Paul Moran, Jamie Goggins
Civil Engineering Research in Ireland 2020
Improving the energy efficiency of buildings via retrofitting is seen as one of the key mitigation measures to reducing the energy demand and carbon emissions of the built environment in Ireland. However, while energy efficiency retrofits for buildings are effective in theory, the energy savings estimated by statistical or engineering models can often be inaccurate. The Domestic Energy Assessment Procedure (DEAP) is the standard assessment procedure used for assessing the energy performance standard of residential buildings in Ireland. This paper examines the gas energy demand for space and water heating and the internal temperature profiles in contrast to DEAP estimates …

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 …

Civil Engineering Research in Ireland 2020
The concept of creativity being only associated with writers, painters, and artistic professions is outdated. The future engineer must embrace maths, art and creativity to unlock innovative solutions. Traditional engineering courses with an emphasis predominately on maths and science can produce graduates who are constrained in developing design solutions without creativity to unlock innovative solutions. This paper describes a short course introduced in the School of Engineering at NUIGalway in 2018 to expose students to creative thinking research and principles and engage in various forms of creative expression (photography, painting and essay writing) to articulate their response to a set …

Teaching Of Structural Analysis Into The Future, Dermot O'Dwyer
Civil Engineering Research in Ireland 2020
The engineering curriculum has always been full. In the past civil and structural engineers studied a wide variety of technical subjects within the broad field of engineering science and spent many hours working on design projects. Modern engineering curricula try to cover these areas while also dedicating more time to structured group-work, report writing and communication skills. Although students spend longer in college the number and range of technical fields that students must master is considerably larger than in the past. As a result the time available to any one topic area has reduced. At the same time the work …

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
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.

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
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.

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
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
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 …

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 …

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. …
