Continuous structural health monitoring for short and medium span bridges

Résumé

In this paper, although there are some useful monitoring methods for short and medium span(10-20m) bridges based on the qualitative or quantitative information, mainly two advanced structural health monitoring systems are described to review and analyses the potential of utilizing the long term health monitoring in safety assessment and management issues for short and medium span bridge. The first system is a special designed mobile in situ loading device (vehicle) for short and medium span road bridges to assess the structural safety (performance) and derive optimal strategies for maintenance using reliability based method. The second system is a long term health monitoring method by using public buses as part of a public transit system (called "bus monitoring system") to be applied mainly to short and medium span bridges, along with a safety index, namely, "characteristic deflection" which is relatively free from the influence of dynamic disturbances due to such factors as the roughness of the road surface, and a structural anomaly parameter.

Pont

vignette|Pont permettant le passage de la ligne C du métro de Rotterdam, à Capelle-sur-l'Yssel (Pays-Bas). vignette|Pont sur la rivière Moyka à Saint-Pétersbourg, Russie Un pont est un ouvrage d'art qui permet de franchir un obstacle naturel ou artificiel (dépression, cours d'eau, voie de communication, vallée, ravin, canyon) en passant par-dessus. Le franchissement supporte le passage d'humains et de véhicules dans le cas d'un pont routier, ou d'eau dans le cas d'un aqueduc.

Public transport bus service

Public transport bus services are generally based on regular operation of transit buses along a route calling at agreed bus stops according to a published public transport timetable. Stagecoach While there are indications of experiments with public transport in Paris as early as 1662, there is evidence of a scheduled "bus route" from Market Street in Manchester to Pendleton in Salford UK, started by John Greenwood in 1824. Another claim for the first public transport system for general use originated in Nantes, France, in 1826.

Road surface

A road surface (English), or pavement (American), is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, macadam, hoggin, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course. Asphalt mixtures have been used in pavement construction since the beginning of the 20th century and are of two types: metalled (hard-surfaced) and unmetalled roads.
