Integral Abutment Bridges: The European Way

Seismic fragility assessment of integral precast multi-span bridges in areas of moderate seismicity

“…According to Kaufmann (2011), integral bridges are commonly used on the highways of Switzerland. An overview by White et al (2010) comparing the European and US practice about integral bridges confirms that several other European countries (e.g. Austria, England, Finland, France, Ireland, Luxembourg, Germany, Sweden, etc.)…”

Capacidad resistente de pilas metálicas tubulares circulares rellenas de hormigón (CFT) en puentes integrales

“…En los trabajos de Feldman et al (2) y White et al (3), así como en la "Guía para la concepción de puentes integrales en carreteras y autopistas" (4), del Ministerio de Fomento, pueden consultarse detalles de proyecto y construcción de puentes integrales y, en particular, de sus pilas.…”

“…Dicho modelo contiene un parámetro β (ecuación [1] que define dos factores: i) ν c [3] el cual depende de νc' [2] y ii) ν s =0,5. Posteriormente, la resistencia del hormigón se incrementa proporcionalmente a este parámetro y a otras relaciones geométricas del tubo (ecuaciones [4] [5] [6].…”

Field monitoring study of an integral abutment bridge supported by prestressed precast concrete piles on soft soils

“…Survey has been conducted on the construction experience of IABs in American [16] and European countries [4,25], where many similarities were observed even though significant differences existed in some aspects. Field monitoring study methods have been adopted to investigate and justify the design and construction concepts, including (a) the maximum allowable design criteria (e.g., total and individual bridge's span lengths and skews); (b) the structure design parameters (e.g., orientations of the pile, abutment, and wingwall); (c) the soil-structural interaction behaviors (e.g., between the soil-pile, abutment-backfill, and approach slab-backfill); (d) the joint connection effects (e.g., at the interfacial locations between the abutment-deck-girder, abutment-pile cap, approach slababutment, and intermediate pier-girder); (e) the stress relief http://dx.doi.org/10.1016/j.engstruct.2015.09.004 0141-0296/Ó 2015 Elsevier Ltd.
