A Bridge-Rehabilitation Strategy Based On The Analysis Of A Bridge-Inspection Data Set, Liam Dromey, Kieran Ruane, John J. Murphy, Brian O'Rourke, Seán Lacey

Publications

Bridge-management systems (BMSs) allow bridge owners to assess the condition of their bridge stock. However, not all BMS packages have the capability to formulate network-level bridge-rehabilitation investment strategies. This research has developed a decision-support system for bridge owners in the selection of the best strategy for bridge rehabilitation at the network level. The basis of the research is an available data set of 1367 bridge-inspection records for County Cork, Ireland, that has been prepared to the Eirspan BMS inspection standard. The developed system consists of a project-prioritisation procedure that builds on previous research, a methodology for the calculation of a …

Reinforced Concrete Deterioration Of A 100 Year Old Structure In A Marine Environment, Ross O'Donovan

Theses

The current study investigates the deterioration of a 100 year old bridge located in a harsh marine environment. Constructed in 1908 - 1909 the Mizen Head Footbridge was one of the oldest reinforced concrete bridges in Ireland. The demolition of the bridge in 2009 provided a unique opportunity to examine its service life and to extract samples for analysis and investigation. A review of the construction of the bridge, and its maintenance history are presented, with a view to analysing their influence on the behaviour of the concrete.

Reinforcement corrosion due to chloride attack was identified. A focused study indicates …
