(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)At the broadest level, the objective of this research work was to examine approaches to improving the sustainability of transport. This objective is accomplished by evaluating the impact of introducing two methods of ... -
Evaluating universal design : exploring methodologies for rating universal design qualities in buildings
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)Universal design (UD) is an approach to design that places the user at the focal point of the process, and extends the understanding of who is a user is. It is focused on redefining the aims of architectural design toward ... -
Seismic reliability assessment of ageing integral bridges
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)This thesis carries out a tune dependent seismic risk assessment of ageing integral bridges as well as providing a comparison between the seismic performance of integral and jointed bridges. -
Detection and assessment of damage in underwater marine structures using image processing based techniques
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)The monitoring of underwater structures is often beset by limited access, exorbitant costs and inherent safety issues. This thesis focuses on developing and implementing automated image processing based Non-Destructive ... -
Public transport, security technology and privacy : an analysis of operator organisation and public response
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)This thesis reports the results of research which examined the potential use of new security technologies in the setting of public transport. The research aimed to consider both the security and privacy implications of new ... -
