An Investigation Of Transverse Load Distribution In Masonry Arch Bridges, Helen Dunne
An Investigation Of Transverse Load Distribution In Masonry Arch Bridges, Helen Dunne
Theses
Masonry arch bridges comprise a significant proportion of the bridge stock both nationally and internationally. They have proven to be enduring structures, far surpassing their design lives and with relatively low life-cycle costs, are environmentally friendly (Sustainable Bridges, 2007).
New masonry arch bridges are not generally constructed. However, their ageing materials paired with ever increasing traffic loads have led to the necessity for their periodic re-assessment. Masonry arch bridge design was predominantly by rule of thumb and their re-assessment has been subject to a number of simplified assumptions. One such simplification, the bridge “effective width” is studied in this thesis. …
