Les ponts en arc font actuellement face au double défi de protéger leur patrimoine et de rivaliser avec d'autres formes plus récentes de structures. La conservation des ponts en arc implique de multiples impératifs : une politique saine d'inspection et de suivi, des méthodes précises d'investigation, une évaluation fiable et un éventuel diagnostic, des moyens efficaces de maintenance, de réparation, de renforcement et d'élargissement. Pendant que des ouvrages existants sont réparés et revalorisés, de nouveaux ponts en arc, de -nies traditionnelles et à " l'échelle humaine ", continuent à se construire, en utilisant des matériaux et procédés améliorés et rentables, assurant longévité et respect de l'environnement. Au premier plan de cette continuité, les concepteurs des ponts en béton, dans les hémisphères Nord et Sud, s'efforcent avec succès de réaliser des portées en arc de plus en plus longues, frôlant les 400 mètres dans les années 1980. Récemment, sur d'autres sites spectaculaires, des records de portées ont été battus par trois ponts en arc respectivement en pierre, en béton, en tubes d'acier remplis de béton. Une telle avancée ne manquera pas d'inciter les ingénieurs à rechercher des formes d'arc encore plus audacieuses et élégantes. Sur le large éventail des thèmes proposés, de nombreux auteurs, de plus de vingt-cinq pays, ont apporté des contributions majeures rappelant que les ponts en arc n'ont rien perdu de leur actualité et que, malgré les leçons assimilées de leur prestigieux héritage, leur conception stimule toujours la créativité des ingénieurs et des architectes. Ces contributions sont réunies dans le présent volume édité à l'occasion de la Troisième Conférence internationale sur les Ponts en Arc, tenue à Paris en septembre 2001. Arch bridges face at present the double challenge of protecting their heritage and competing with other more recent structural forms. The conservation of the arch bridge heritage successively requires sound inspection and monitoring policies, accurate investigative methods, reliable assessment and eventual diagnosis, efficient means for maintenance, repair, strengthening and widening. While existing structures are being repaired and upgraded, new arch bridges, of traditional forms and on a "human scale", continue to be constructed, using improved and cost-effective materials and procedures, ensuring longevity and respect for the environment. In the forefront of this continuity, concrete bridge designers, in the northern and southern hemispheres, have successfully been striving for ever larger arch spans, closely approaching 400 m in the 1980's. Lately, at other spectacular sites, span records were beaten in three arch bridges respectively using stone, concrete and slender concrete-filled steel tubes. This breakthrough may encourage engineers to seek more daring and elegant forms of arch. On the broad spectrum of the suggested topics, numerous authors, from more than twenty-five countries, have recently offered major contributions, reminding that arch bridges have nothing lost of their appeal and that, for all the lessons learnt from their prestigious heritage, their design still simulates the creativity of engineers and architects. These contributions are put together in the present volume edited on the occasion of the Third International Arch Bridge Conference held in Paris in September 2001.
