“…In terms of seismic performance this type of bridges has exhibited, in the past, better response compared to traditional bridges: in particular, after the 1989 Loma Prieta and 1994 Northridge earthquakes in California, after the 2010–2011 Canterbury seismic sequence and 2013 Lake Grassmere earthquake in New Zealand and after the 2011 Tōhoku Earthquake in Japan 3–5 . Despite these advantages, the main issue remains, that is dealing with the soil‐structure interaction of the abutment walls and the supporting piles under various loading condition, especially for seismic actions 6 . Indeed, the mandate for the revision of the structural Eurocodes, specifically indicated seismic design of IABs among the necessary extension of scope.…”

Integral abutment bridges (IABs) are becoming the solution of choice in the low to mid‐length ranges because of their low cost compared with traditional solutions and their good performance under seismic actions. The main drawback of these bridges is the need to consider soil‐structure interaction to assess their performance, a problem that is more pronounced for actions implying horizontal deck movements, such as temperature or the specific focus of this paper, that is, seismic action. In IAB design, simplified models are often used, where soil‐structure interaction is modeled by means of beams on non‐linear Winkler springs for the evaluation of seismic behavior. This paper, starting from an existing non‐linear dynamic model (NLDM) that describes IABs longitudinal seismic response, derives two equivalent static models: one non‐linear and the other linear, for displacement‐ or force‐based design respectively. A parametric study is carried out to assess the static models performance in terms of the main design internal actions versus the NLDM. Finally, the assessed model errors are discussed in the context of partial factors safety format.

“…The country with the largest number of IABs is by far the USA, with tens of thousands of structures built from the 1930s to date 3 . Since the 1950s, this structural typology has been largely employed also in Europe, 4–7 where the construction practices differed somewhat from those adopted in the USA 8,9 . More recently, IABs have been realized in many other countries, e.g.…”

The seismic performance of integral abutment bridges (IABs) is affected by the interaction with the surrounding soil, and specifically by the development of interaction forces in the embankment‐abutment and soil‐piles systems. In principle, these effects could be evaluated by means of highly demanding numerical computations that, however, can be carried out only for detailed studies of specific cases. By contrast, a low‐demanding analysis method is needed for a design‐oriented assessment of the longitudinal seismic performance of IABs. To this purpose, the present paper describes a design technique in which the frequency‐ and amplitude‐dependency of the soil‐structure interaction is modelled in a simplified manner. Specifically, the method consists of a time‐domain analysis of a simplified soil‐bridge model, in which soil‐structure interaction is simulated by means of distributed nonlinear springs connecting a free‐field ground response analysis model to the structural system. The results of this simplified method are validated against the results of advanced numerical analyses, considering different seismic scenarios. In its present state of development, the proposed simplified nonlinear model can be used for an efficient evaluation of the longitudinal response of straight IABs and can constitute a starting point for a prospective generalisation to three‐dimensional response.

“…Expansion joints and moveable bearings on the extremes of the deck are replaced with control joints located at the end of the approach slab, where joint leakage does not adversely affect the structure. When the foundation has greater flexibility and less resistance to longitudinal movement, stress from longitudinal forces can be minimized [8][9][10]. Figure 4 shows the integral abutment connection details used by the Pennsylvania Department of Transportation [11].…”

Bridges are one of the most critical parts of transportation networks that may suffer damages against earthquakes. Also, seismic responses of most bridges are significantly influenced by soil-structure interaction effects. Taking out expansion joints in the bridges may cause many difficulties in design and analysis due to the complexity of soil-structure interaction and nonlinear behavior. The secondary loads on an IAB include seismic load, temperature variation, creep, shrinkage, backfill pressure on back wall and abutment, all of which cause superstructure length and stress variations in girder changes. The purpose of this study is to recognize the most effective parameters of analysis IABs. Findings show that the backfill material behind the IABs has a significant effect on the performance of IABs. Using a compressible material behind the abutments would enhance the in-service performance of IABs. Finally, behaviour of abutment may be greatly affected by thermal load and soil pressure. Thermal expansion coefficient significantly influences girder axial force, girder bending moment, and pile head/abutment displacement.
