The reliability of spread foundations designed to Eurocode 7
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2011)The main objective of the research work described in this thesis is to evaluate the reliability of spread foundations designed to Eurocode 7 using the partial factors and Design Approaches adopted in the Irish National ... -
The Role of Carbon Dioxide Emissions Information in Personal Travel Choices
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)This thesis presents the results of an examination of the role of carbon dioxide emissions information in the personal transport sector. With the widespread acceptance that human transport activities are contributing to ... -
The role of the near-surface pathways in the delivery of flow and nutrients to streams in Irish catchments
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)Management of pollution from diffuse agricultural and small point sources remains a significant challenge worldwide. Understanding and quantifying the contributions of flow and nutrients, through each hydro(geo)logical ... -
The role of value of information in multi-agent deep reinforcement learning for optimal decision-making under uncertainty
(2023)To preserve structural safety of deteriorating engineering systems through optimal maintenance, it is imperative to efficiently integrate structural health information with decision-making optimization frameworks. Although ... -
The stability of fully and partially embedded beam-columns in elastic Winkler foundations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 1996)The stability, in terms of the buckling load, of fully and partially embedded piles that are supported laterally along their embedded length by an elastic Winkler foundation is investigated. Exact solutions are presently ... -
The thermo-hygrometric properties of multi-purpose historic buildings
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)The concept of sustainability is a multi-faceted one, with environmental, social and economic aspects all requiring consideration when assessing the sustainability at a micro or macro scale. Accordingly, when considering ... -
The Uncertainty of Damping Ratios Obtained Using Modal Identification Techniques and Full-Scale Acceleration Data
(2023)The damping ratio of a structure has a large influence on its ability to meet serviceability and habitability requirements under dynamic loading. In practice, design analysis relies on estimates of damping ratios from ... -
The Use of Autoregression to Generate Patterns of Extreme Loading on Long-Span Bridges
(2023)For long-span bridges, there is little known about the gaps between vehicles in the congested traffic loading events that govern the characteristic maximum load effects. In many studies for the derivation of national ... -
The use of counter-moments for steel beam strengthening
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2007)Many methods exist for the repair and strengthening of beams. With increasing traffic volumes and axle weights, the demand for performance of highway structures has increased. In new construction the demand optimised ... -
The use of ICT to re-engineer purchasing in Irish construction
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2007)The process traditionally adopted in the purchasing of materials in the construction industry is investigated. There are millions of trading documents, such as orders, delivery notes and supplier invoices, currently exchanged ... -
Theory of liquid and plastic limits for fine soils, methods of determination and outlook
(2024)Albert Atterberg introduced various consistency limits (state transitions) for fine-grained soil in the 1910s. Of these, the liquid limit (LL) and plastic limit (PL) are ubiquitous in geotechnical engineering practice, ... -
Theory of the Development of Safety in Codes of Practice
(2023)Nowadays, the required safety of structures is achieved in codes of practice through computational verifications and qualitative requirements, e.g., on the building materials and the construction processes. Both the ... -
There's no such thing as cycle traffic: a critical discourse analysis of public opposition to pro-cycle planning
(2024)Across a variety of low-cycling contexts, there are ambitious targets to reduce private car use and increase cycling to decarbonise everyday mobility practices. A component of many plans to achieve this modal shift is ... -
Thermal energy modelling, benchmarking and mapping for university campus buildings
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2017)According to the Chartered Institution of Building Services Engineering, CIBSE TM46:2008 University Campus benchmark, a college building needs 240 kWh/m2 of thermal energy and proportionally produces 45.6kg CO2 per annum. ... -
Thermal performance and fitness of glacial till for Rammed Earth construction
(2019)The search for sustainability caused a revival of earth construction. Rammed earth (RE) construction is often preferred as compaction and stabilization leads to stronger, more consistent materials. Tills are glacial ... -
The thermo-hygrometric environment in cathedrals in Ireland
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)Research was carried out into the often conflicting concepts of thermal comfort, conservation of artefacts and preservation of the 57 active cathedral buildings on the island of Ireland. Whilst the use to which these ... -
A time and ensemble equivalent linearization method for nonlinear systems under combined harmonic and random excitation
(2023)An Equivalent Linearization technique, termed an Equivalent Linearization Time and Ensemble Expectation (EL-TEE) approach, is used to develop an alternative method for estimating the response of a nonlinear oscillator to ... -
