Effects Of Openings On The Analysis And Design Of Precast Prestressed Hollow Core Slabs, Eoghan Lodge
Effects Of Openings On The Analysis And Design Of Precast Prestressed Hollow Core Slabs, Eoghan Lodge
Theses
Precast prestressed hollow core floors are a widely used structural element which offers increased speed of construction, reduced self-weight and many other advantages. Due to the relatively low span-to-depth ratio and the speed of construction hollow core slabs are utilised in a large number of commercial buildings. In order to carry the services to the upper floors an opening must be made within the prestressed slab. Cutting an opening in a prestressed slab has significant effects on the structural behaviour of the slab and can considerably reduce the ultimate capacity of the slab.
This paper outlines the limited available guidance …
The Potential For The Elimination Of Expansion Joints And Bridge Bearings From Existing Road Bridges In Ireland, Conor Keena
The Potential For The Elimination Of Expansion Joints And Bridge Bearings From Existing Road Bridges In Ireland, Conor Keena
Theses
This research was focused on determining the feasibility of eliminating expansion joints and bridge bearings from existing short to medium span road bridges in Ireland. It is possible that this could provide a significant long-term economic benefit to bridge owners. A literature review was carried out as part of the research. This included investigations into research conducted in the areas of thermal movements of bridges, concrete creep and shrinkage, soil-structure interaction, lifetime costing, design standards and finite element analysis, and the elimination of bridge expansion joints in other countries.
Finite element analyses were carried out on two existing road bridges. …
