Arch bridges: Design - Construction - Perception
The arch bridges have an historical development, that is rooted in their ancient tradition, yet are also very successful to this day, a rediscovery of the earliest arched forms can be seen in the most recent innovations. After millennia of masonry arch bridges and almost two centuries of relentless …

Multi-Objective optimization of arch bridges
Trussed arch bridges are commonly used to attain big spans. They are efficient structures that offer a wide range of geometries, materials, and topologies. This thesis studies the influence of the geometry and topology of arch bridges on both their structural performance relayed by the maximum …

Semplified seismic Vulnerability Assessment of Masonry Arch Bridges
… seismic vulnerability assessment of masonry arch bridges with common typologies in Europe. Bridges are, in most cases, the most vulnerable elements in the transportation network during an earthquake; therefore, their seismic vulnerability assessment is necessary for a proper planning of the …

Static and dynamic characterization of tied arch bridges
<p>"Tied arch bridges have been designed and constructed since the late 19th century. With their open vista owing to minimalist features tied arch bridges continue to appeal the public. Tied arch bridges are both aesthetic and economical alternates to long span bridges holding a place in the …

Automated Image-Based Inspection of Masonry Arch Bridges
Masonry arch bridges have proven to be durable and underpin much of the world’s transport infrastructure. However, they are an aging asset, and their effective management is challenging. Existing management focuses heavily on manual inspection, which has been shown as subjective and often leads to …

Live Load Testing of Appalachia, Va Concrete Arch Bridges for Load Rating Recommendation
… infrastructure ages, many of the nation's bridges approach the end of their service life. In order to develop a method for handling the rising number of deficient and functionally obsolete bridges, nondestructive tests and evaluations must be undertaken. Valuable information from these …

Dynamic distributed monitoring of masonry railway bridges
… behaviour of complex structures, such as masonry arch bridges. These bridges, which are common features of many European transport networks, are often ageing structures, with complex histories of damage and repair work. Furthermore, their material properties and non-visible geometry may be …

Design and performance of Thomas Telford's Bonar Bridge and Mythe Bridge
This paper assesses two cast-iron arch bridges of Thomas Telford (1757-1834) - Bonar Bridge (1810-12) and Mythe Bridge (1824-26) - to draw a broader conclusion about his career in bridge building. The bridges are introduced and Telford's design influences are investigated. While Telford was …

Behaviour and analysis of a flexible concrete arch
… early 20,h century led to a decline in masonry arch bridge building. Traditional masonry arch construction is time consuming and involves considerable formwork usually in the form of timber centring, as well as traditional skills. It is also limited by the spans at which the design is efficient. …
