“…Typically, for the IAB, the H-section pile is oriented at its weak axis to ensure flexibility in the lateral displacement of the super-structure [9][10][11][12][13]15,16,33]. However, in a skew bridge, it is difficult to precisely orient the pile at its weak axis as torsion is generated on the pile-head [2].…”

“…The structural analysis model of the IPM bridge ( Figure 7) was created by the design drawings in Figure 5 and references previous IAB studies [8][9][10][14][15][16]30,31]. The detailed structural analysis model of the IPM bridge is equivalent to the Park and Nam [2] model.…”

“…In addition to thermal expansion, which causes the lateral displacement of the super-structure as well as the CR and the drying shrinkage of the time-dependent load, consideration of the dead load (DL) and live load (LL) in the structural analysis of the IPM bridge is basically the same as in the IAB [2,10,15,30]. Each load condition complies with the Korea Bridge Design Code [49] of the Ministry of Land, Transport and Maritime Affairs (MLTMA) and the Standard Specifications for Highway Bridges [50] of the American Association of State Highway and Transportation Officials (AASHTO).…”

“…Such a lateral displacement is affected by the thermal expansion of the girder, which is further influenced by creep (CR) and shrinkage (SH) [30][31][32]. Therefore, the span of an IAB is limited so as not to exceed the maximum pile-head bending moment capacity when resisting bending that is caused by excessive lateral displacement of the girder [9,10,33,34]. To reduce this limitation, studies involving the hinge bar and elastic pad installed in the IAB abutment for the purpose of reducing the maximum pile-head bending moment are ongoing [9,[35][36][37].…”

Abstract:A bridge with an integrated and pile-bent abutment with a mechanically stabilized earth-wall (IPM) was developed by separating earth pressure from the abutment to overcome the problems typically faced by integral abutment bridges. Also, the IPM bridge removes expansion joints and bearing by integrating the super-structure and the abutment and does not need many piles because it separates the earth pressure from backfills. Therefore, it is superior in cost, durability, and maintainability to traditional bridges and is sustainable due to using less material. A numerical analysis was conducted to ascertain the behavior of the IPM bridge according to its super-structural and sub-structural characteristics. Based on the analysis results, the behaviors of the IPM bridge are as follows: The bending moments M y of the pre-stressed concrete (PSC) girder and the steel-plate girder of the bridge were influenced by the presence of the time-dependent loads. The contraction behavior in the PSC girder is largely due to the time-dependent loads, whereas the expansion behavior in the steel-plate girder is large due to its greater thermal expansion coefficient and temperature range compared with those of the PSC girder. In general, the suggested bridge length limit for PSC girders in both the integral abutment bridge and the IPM bridge is larger than that in a steel bridge. This needs to be reviewed again with consideration of the long-term and seasonal behaviors.

“…Only recently, Dicleli and Erhan [12] have conducted a limited research study on live load distribution in IB girders. Most research on IBs is concentrated on the performance of such bridges under thermal effects [13][14][15][16][17][18]. Thus, in this study, LLDEs for the substructure components of single-span IBs are developed to address the above mentioned uncertainties and to provide useful tools to the bridge engineering community at large for the design of IB abutments and piles under live load effects.…”

Bei Entwurf und Planung von Brückenbauwerken stehen neben der Tragsicherheit und Gebrauchstauglichkeit auch die Fragen der Nachhaltigkeit, Wirtschaftlichkeit und Instandhaltung im Fokus. Verbundbrücken mit integrierten Widerlagern sind deswegen eine wirtschaftliche Alternative. Sie erweisen sich als günstiger im Bau und Unterhalt, da Lager und Fugen, welche einen großen Anteil an den Gesamtwartungskosten des Bauwerks ausmachen, fehlen. Jedoch konnten bisher in den meisten europäischen Ländern nur wenige Erfahrungen mit integralen Widerlagerbrücken, insbesondere in Verbundbauweise, gesammelt werden, so dass die Verbreitung dieses Brückentyps nur zögerlich erfolgt. Durch Forschungsarbeiten, über die auszugsweise in dem Aufsatz berichtet wird, können offene Punkte bei der Bemessung weiter geklärt werden, so dass die Vorteile langfristig sinkender Instandhaltungskosten besser ausgenutzt werden können.Integral abutment bridges.Within the design and construction of bridges, questions of sustainability, maintenance and durability become more and more important for European road administrations in addition to safety and serviceability issues. Therefore integral abutment bridges turn out to become highly attractive to designers, constructors and road administrations. The main reason for this is that they tend to be less expensive to build, easier to maintain and more economical to own over their life time. This is principally due to the non‐existence of bearings and joints, that are main sources of maintenance costs during life time. However, in most European countries only few experience with integral bridges has been gained so far. Thus road administrations often are reluctant in using types of bridges like this. Nowadays this lack is more and more filled. Therefore with further assessment the share of integral abutment bridges in the European bridge stock has the potential to increase significantly with the advantage of reduced maintenance costs.
