A methodology for assessing the load capacity of cantilevered stone stairs
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)Cantilevered stone stairs were widely constructed from the 17th to the 20th century. Thousands of these stairs were built in Ireland and across Europe during this period and they have proven to be very robust. However, the ... -
A new approach to driving cycle development and its applications
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Driving cycles describe the general driving pattern of a vehicle in a road network, and are usually represented by speed-time profiles of equal spacing. They are used to approximate and represent driving conditions as an ... -

(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)This dissertation evaluates the results from a multi-level multidisciplinary study on the effect of energy efficient upgrading on social housing. The National Energy Efficiency Action Plan aims to deliver a 20% national ... -
A stated preference analysis of real time public transport information
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2008)This thesis reports the outcomes of a study conducted to ascertain the benefits derived from the use of real-time public transport information. The study focuses upon three areas of individuals preferences in relation to ... -
A study of the properties of lime-hemp concrete with pozzolans
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Lime-hemp concrete is a sustainable building material suitable for certain construction applications. It is a mix of a lime-based binder, hemp and water. Hydraulic lime and cement are often added to the binder to enhance ... -
A study on hydrodynamics of grit particles in curved open channels using physical and computational modelling
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2007) -
A study on the deployment and acceleration of low carbon technologies
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The work presented in this thesis is an investigation into the variables that are considered by consumers when selecting low carbon technologies (LCT) and the barriers that are encountered by implementers when deploying ... -
Active strategies with TMDs for control of wind turbine vibrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)This thesis investigates the use of active structural control techniques for the mitigation of the dynamic response of wind turbines with particular emphasis on reducing the in-plane (edgewise) vibrations in wind turbine ... -
Air quality monitoring and modelling at motorway and roundabout sites in Ireland
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2005)EU legislation requires Ireland to set ambient air quality objectives, assess the ambient air quality, gather information on ambient air quality and make it available to the public, and to maintain or improve the ambient ... -
An 'Urban Spacebook' : re-mapping the city with mobility practices and experiences
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)This thesis argues that urban sustainability cannot be reached without city inhabitants becoming more connected and engaged with their city and participating (inter)actively in planning their environments. It acknowledges ... -
An analysis of cycling safety perceptions and development of a bicycle trip assignment methodology
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)This thesis reports the outcome of research on the development of an alternative method to modelling the assignment of bicycle trips in multi-modal networks. The proposed methodology considers the effects of safety (or ... -
An assessment of the performance of willow evapotranspiration systems for the treatment of on-site wastewater in Ireland
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)In Ireland, domestic wastewater from approximately 400,000 dwellings is treated by on-site systems which are all designed to distribute the treated effluent to groundwater via the subsoil on the site. Low permeability ... -
An examination of the parameters involved in the design of a continuous flow solar disinfection process
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2006)The aim of this research was to assess a number of parameters that affect the continuous flow solar disinfection process.

An experimental study of the physical properties of lime mortar and their effect on lime-mortar masonary
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The objective of this research is to provide new data in respect to the mechanical behaviour of lime mortar and masonry traditionally used in Ireland, especially the effect of water content and curing time and curing ... -
An investigation into the effects of the density of on-site wastewater treatment systems on Irish aquifer
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Groundwater is an important resource in Ireland and given that over 25% of all water supplies are currently provided directly from groundwater abstractions, it is critical to protect this resource from contamination. Most ... -
An investigation into the optimisation of a solar photocatalytic continuous flow disinfection system
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2010)Solar photocatalytic disinfection is thought to be a safe, effective, low-cost method of drinking water treatment and would be applicable, for example, to village-scale systems in developing countries.
