Impact Of Occupant Behaviour On Indoor Environment Of A-Rated Dwellings, Niti Saini, Patrick Shiel, Roger P. West, Ruth Kerrigan, Ian Pyburn
Civil Engineering Research in Ireland 2020
An increase in energy efficiency and airtightness in the absence of adequate ventilation in A-rated houses has brought about an increase in indoor environment quality (IEQ) issues which can lead to health hazards, such as mould formation due to high humidity levels, or the sustained presence of Carbon Dioxide, both generated by human activities. Relative humidity above 80% for prolonged periods can result in mould growth on any cold unventilated surfaces, such as behind curtains, blinds, wardrobes, etc. Levels of humidity can also affect an occupant’s feeling of well-being, for example, low levels of humidity can lead to drying of …
Key Considerations In The Design Of A One-Stop-Shop Retrofit Model, Orlaith Mcginley, Paul Moran, Jamie Goggins
Key Considerations In The Design Of A One-Stop-Shop Retrofit Model, Orlaith Mcginley, Paul Moran, Jamie Goggins
Civil Engineering Research in Ireland 2020
The Irish Government’s Climate Action Plan emphasizes the need for increased retrofit activity within the built environment. As such, the plan has set targets for the completion of 500,000 energy efficient retrofits by 2030 at a rate of 50,000 per annum. Ireland’s current retrofit uptake rate is considered relatively low, at approximately 23,000 primarily shallow retrofits per annum. Thus, a significant step change is required to drive retrofit investment at a national scale, however, there are various barriers existing to such. Considering these targets, the establishment of a One-Stop-Shop (OSS) retrofit model has been identified in the Climate Action Plan …

Thermoelectric materials enable direct conversion of thermal energy to electricity. Ambient heat energy harvesting could be an effective route to convert buildings from being energy consumers to energy harvesters, thus making them more sustainable. There exists a relatively stable temperature gradient (storing energy) between the internal and external walls of buildings which can be utilized to generate meaningful energy (that is, electricity) using the thermoelectric principle. This could ultimately help reduce the surface temperatures and energy consumption of buildings, especially in urban areas.

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 …

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 …

Demountable Reinforced Concrete Structures: A Review And Future Directions, Tahreer Fayyad, Ahmed Abdalqader
Civil Engineering Research in Ireland 2020
Consuming about 60% of natural resources, construction industry recently has been under a continuous pressure to ensure an efficient consumption of natural resources. Recent decades have witnessed some valuable steps toward making the construction industry more sustainable. This includes the trials to change the linear life cycle model to cyclic one by the consideration of the 3Rs; recycling, reusing and reducing to help in closing the material loop. However, recent studies have showed that the reason for demolition is not really the end-of-life span of structures but actually the lack of adaptability, also, demolition and recycling demand huge energy. So …

Examining Large Student Cohorts - A Question Of Questions, Roger P. West, Michael A. Wride
Civil Engineering Research in Ireland 2020
With pressure to increase student numbers on academic courses worldwide, the trends in exam marks distribution for subject modules become more acute, with more distinct pattern characteristics reflecting student choices, topic and exam question difficulty, and lecturer marking severity, refinement and consistency. The practice of representing the overall exam results in a module through histograms enables normality, skewness and randomness to be identified, interrogated and understood. However, when dealing with large numbers of exam candidates (of the order of 1000 or more), an investigation of the averages and histograms for individual exam questions can further reveal refined explanations for poor …

Effect Of Casting Method And Test Setup On Flexural Characterization Of Uhpfrc, Yuanye He, Esmaeel Esmaeeli, Marios Soutsos
Civil Engineering Research in Ireland 2020
Ultra-High-Performance Fibre Reinforced Concrete (UHPFRC) has received extensive attention due to its excellent mechanical properties. UHPFRC not only offers a very high compressive strength, but also a unique tensile strain-hardening behaviour. Casting method is critical as it determines the fibre alignment, which in turn affects the performance of UHPFRC. In practice, casting in one single pour requires large equipment, large volume of concrete and it is time consuming and in general difficult to achieve. To evaluate the flexural behaviour, 3PB (three-point bending) and 4PB (four-point bending) tests are generally carried out following the methodologies recommended by the material testing standards, …
Finite Element Appraisal Of The Strut And Tie Method For The Design Of Reinforced Concrete Structures, Seán Quinn, Kieran Ruane
Finite Element Appraisal Of The Strut And Tie Method For The Design Of Reinforced Concrete Structures, Seán Quinn, Kieran Ruane
Civil Engineering Research in Ireland 2020
The Strut-and-Tie Method (STM) can be used for the design of reinforced concrete elements such as deep beams and pile caps. STM allows the reduction of complex states of stress, which are known as D- or Discontinuity regions, within a structure to an assembly of simple stress states. Normal beam theory where B- or Bernoulli regions occur, does not apply. Up until recent times, design for deep beams was generally on simple rules and empirical formulas, however STM is now included in most modem design code provisions. Yet, there still remains a lack of clear understanding of the STM.

Civil Engineering Research in Ireland 2020
Use of finite element modelling (FEM) to predict structural behaviour under static and dynamic loading conditions is a well-established aspect of the bridge design process. The Cherrywood Luas viaduct carries the Luas light rail system through proposed development lands at Cherrywood, South County Dublin. As part of development plans in the area it is proposed to create a new street adjacent and parallel to the existing viaduct with associated footpaths and landscaping. It is proposed to integrate the new structure supporting the street into the existing light rail bridge structure.
Probabilistic System Analysis – Practical Examples For Railway Bridges, Lorcan Connolly, Marko Duranovic, Róisín Donnelly
Probabilistic System Analysis – Practical Examples For Railway Bridges, Lorcan Connolly, Marko Duranovic, Róisín Donnelly
Civil Engineering Research in Ireland 2020
The issue of maintenance of ageing bridges with insufficient budget allocations is well documented throughout Europe and beyond. To combat the issue of out of date assessment standards, insufficient structural information and deteriorating bridges, probabilistic assessment bridge techniques have evolved significantly over the past number of years. Previously, probabilistic analysis methods have been applied at the element level, where the highest element failure probability is assumed to govern for the structure. This fails to account for inherent redundancy which is often present in bridge structures. For example, the development of a plastic hinge due to elastic failure in a steel …

Beam-To-Column Minor Axis Moment Connections, Ali Purcell, John J. Murphy, Kieran Ruane
Civil Engineering Research in Ireland 2020
Steel moment connections are used where continuity is required between beam and columns. Research on moments connections has primarily focussed on major-axis connections. An in-depth investigation of I.S. EN 1993-1-8 was completed to identify the design rules of connections. Simple connections such as cleats, fin plates and splices were investigated briefly in order to gain a greater understanding of how they behave and transfer load before researching two types of minor axis moment connections; one where the end plate is connected directly to the column web and one where the end plate is bolted to another plate which is welded …
Effective Measures To Improve Road Safety At Toll Plazas In Ireland, David Collery, Grzegorz Gorecki
Effective Measures To Improve Road Safety At Toll Plazas In Ireland, David Collery, Grzegorz Gorecki
Civil Engineering Research in Ireland 2020
Road safety statistics from toll plazas, show that the occurrence of collisions in their vicinity is often disproportionally higher than on other sections of the same roads. Despite the presence of lower speed limits in these locations, various manoeuvres, especially on the approaches to toll plazas, pose higher risk of collisions. A lack of strictly unified design standard for Irish toll plazas is the reason for different road safety approach in various locations. The standards are mainly focused on toll plazas operation (Abuzwidah & Abdel-Aty, 2015). Also Abdel-Aty et al. (2016) mentions a clear lack of design codes or guidelines …

Analysis Of Inclement Weather On Traffic Flow – An Irish National Roads Case Study, Beatriz Martinez-Pastor, Páraic Carroll
Civil Engineering Research in Ireland 2020
Transportation networks and infrastructure are increasingly exposed to and effected by inclement weather. The rise in the frequency and intensity of these events is increasingly affecting the normal operation, performance and functionality of roads and highways, leading to costly losses. Inclement weather creates risky and hazardous situations not only on the main roads, such as motorways, but also, on the smaller roads connecting rural parts of the country that experience lower traffic volumes. The effects of weather events, such as rainfalls or snowfalls, have been primarily addressed in main roads, leaving, smaller roads on hold. This has created a lack …
