“…The steel piles of such an abutment are regularly exposed to axial and flexural stresses close or equal to excess of yield stresses. The stress at the top of the pile is sufficient to initiate yield stress in the steel but not sufficient to cause the formation of a plastic hinge [18][19][20][21]. However, for longer IABs, such piling stresses, if large enough, may result in the formation of plastic hinges that may limit the flexural resistance of the piles to additional superstructure elongation.…”

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.

“…Here, the p-y method is a widely used empirical method, with soil pressure p being considered a non-linear function of pile deflection y. Essentially, the method involves introducing a series of p-y curves to represent the true behaviour of the soil by considering the non-linearity of the constrained soil modulus E s,k [19] based on the geotechnical survey. However, due to non-linearities, that concept does not allow for a superposition of load cases.…”

Design of composite bridges with integral abutments

Bridges are of vital importance to Europe's infrastructure and composite bridges have already become a popular solution in many countries, representing a well-established alternative to concrete bridges. Their competitiveness depends on several factors such as site conditions, local costs of materials and labour and the contractor's experience. One outstanding advantage of composite bridges compared with concrete bridges is that the steel girders can carry the weight of the formwork and the fresh concrete during casting. Another major advantage is savings in construction time, which reduces disturbance to traffic and, consequently, saves money for the contractor, but even more so for road users -a fact that has been neglected for a long time. Recently, this factor has increasingly attracted attention as the latest studies show the need to take into account not only simple production costs, but also construction time and maintenance costs when deciding on a specific bridge type. All these needs are met by integral abutment bridges as well. In addition, this bridge type has the potential to outclass traditional bridges with transition joints as it not only reduces production and maintenance costs, but saves on economic and socio-economic costs as well.

“…The first investigation focusing on development of rational design for steel piles was initiated at LTU in late nineties and results are published in [3], and recently in [4] and [ [5]. The major complexity of the integral bridges is actually in soil-structure interaction that requires the coordinated attention of both structural/bridge and geotechnical engineers.…”

Preliminary results obtained from short term test-loading are used to illustrate possibilities of FEM used to calibrate complex interaction characteristics between a pile and soil in a bridge with integral abutments. The measurements are obtained during the winter season on the bridge over Ledån, Northern Sweden. The bridge is built in 2006 and used for long term monitoring within the international project supported by RFCS. The main objective of the on-going research project is to proposed recommendations for rational analysis and design of bridges with integral abutments.
