“…The AASHTO LRFD [28] does not requie any detailed design or analysis methods. In addition, special load combinations for IABs are not given even though boundary conditions of IAB's are different from conventional jointed bridges [29]. To reduce passive pressure developed in abutment backfill by an expanding integral bridge, a number of controls, devices, and procedures are used.…”

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.

“…Although there are many other suspected reasons behind the bridge failure but the failure due to thermomechanical fatigue is the main suspect 16 . An extensive literature is available focusing on thermomechanical fatigue of single‐span FIB abutments 17–19 . Some of the authors experimentally tested FIB prototype models for finding the location of crack initiation and propagation by applying monolithic point loading at different locations 5,20 .…”

In this study, a five‐span fully integral reinforced concrete (RC) bridge has been investigated for fatigue life assessment of its RC piles considering the effects of environmental temperature variation and nonlinear soil characteristics. The effect of daily temperature variation on the abutment wall and pile foundation has been estimated. Multilayers of soil along the abutment pile depth have been considered in the formulations. The soil has been represented as 3D nonlinear springs. A new fatigue model has been used for crack initiation and propagation in the RC piles. In this model, a crack has been assumed to progress successively in three stages from the tension side of the pile. Finite element (FE)‐based modeling and analyses have been carried out to determine the longitudinal displacements and bending moment in piles, abutments, and piers. Furthermore, taking the bending moment as input crack mouth opening distance, crack propagation and fatigue life of pile have been assessed using the FE method‐based software. It is seen that the abutment piles suffer fatigue damage earlier as compared to the pier‐piles as a result of thermal and vehicular loads effects. Also, thermal fluctuation has shown little or no fluctuations in the longitudinal displacements of abutment and piles in the multispan fully integral bridge (FIB). It is expected that the proposed method will be helpful for the bridge engineers in designing the pile foundation passing through multiple soil layers against fatigue damage of a FIB in particular subjected to thermal and vehicular loading.

“…At the time of the study Integral abutment bridges were becoming popular in Europe, but the traditions differs from country to country. Jafar Razmi et al (2013) [7] noticed that piles in integral-abutment bridges (IABs) may affect plastic deformation and fatigue as a result of cyclic loading occurs due to daily and seasonal temperature variations. Habeeba A et al (2015) [8] found that, if the ability of the tool to identify the problem is good then the analytical assessment of bridge will be accurate.…”

In Conventional construction of bridge, the superstructure typically consists of a series of simply supported spans. These structures are separated by expansion joints and resting on bearings at the abutments and piers. In integral construction of bridge, the superstructure and abutments are constructed as continuous structure. Thus the maintenance cost and construction cost is lesser for integral bridges. In integral bridges, joints and bearings are eliminated as it is made integral with intermediate pier. Response of the structure depends on the geometry, material, configuration, soil interaction and construction details of the system. Fatigue evaluation of integral bridges is studied by using deflection characteristics and based on S-N curve. In this paper, finite element tool ANSYS Workbench is used for the study of fatigue behavior of integral and conventional bridge.
