In this paper concrete integral overpass with span of 30 meters on magistral road which based on piles is considered. It is analysed influence of soil stiffness on value of design forces and pile stress. Three types of soil is considered in this analysis, where stiffness of soil was determined with characteristic of soil layers. For this analysis was made numerical model of this overpass in software CSiBridge v20 where is soil modeled with "springs" (flexible supports) placed along the piles whose stiffness match with stiffness of soil layer.

“…Even though the relevant design specifications have not been completed yet, many research reports point out that one of the most main parameters needed considering is the effect of backfilling soil [3,18]. The integral abutment will displace back and forth together with the girder in the earthquake, increasing the interactive effect with the backfill soil which might result in a significant change of the stress in the abutment.…”

The integral abutment bridge (IAB) has been regarded as an efficient and effective seismic design in bridge structures by many civil engineers in recent years. In this paper, some advantages of IAB are shown. By comparing with the traditional abutments, the design of IAB can save the cost of those expansion devices in both the construction phase and maintenance phase. Moreover, the seismic performance of IAB is proved to be better for its unique advantages such as increasing integrity by cancelling the expansion joints and bearings, reducing the backfilling pressure, and limiting the rotation. Therefore, the application of IAB has been spread in many countries, especially in America. However, this paper also conducts some problems in the field of IAB which can be regarded as the potential research direction. The first is the delay of IAB’s application in China and the corresponding urgent requirement. The second is the absence of a unified specification. And the last is that the advanced-performance piles in the integral abutment are expensive. The information presented in this paper aims to help arise and expand the relative emphasis and research in the field of IAB.

“…An IAB is a statically indeterminate structure in longitudinal direction due to these rigid connections, and the substructure stiffness has a significant effect on the stress level induced by thermal loads in the structure [3][4][5][6]. For new IABs, flexible piles like H-shaped steel piles or concrete piles with an enclosure of the top part by a rubber sleeve or filled with loose sand can be used as the foundation [7,8]. However, for most of the existing bridges with expansion joints (jointed bridges), the stiffness of the substructures are generally high and integral design is not feasible; thus, the semi-integral abutment bridges (SIABs) are used to be an alternative of jointless bridges [3,9,10].…”

The semi-fixed dowel joint studied in this paper consists of a steel dowel with rubber sleeves and a rubber pad to connect the superstructure and the substructure and to support the main beam. This type of joint is suitably used in retrofitting a jointed bridge with high-stiffness substructure into a semi-integral bridge. This study aimed to investigate the nonlinear stiffness of the joint, which is the key parameter in the retrofitting design. Taking the real joint in a retrofitted semi-integral bridge as a prototype, tests on full-scale models were carried out, in which the wall thickness of the rubber sleeve and the thickness of the rubber pad were taken as parameters. The test results show that the wall thickness of the rubber sleeve is the main factor affecting the radial stiffness and the flexural stiffness of the semi-fixed dowel joint. With the decrease of the wall thickness of the rubber sleeve, the radial stiffness decreases while the flexural stiffness increases. However, the thickness of the rubber pad has little influence on both the radial and flexural stiffness of the joint, and its main role is only vertical loading-bearing. If the longitudinal deformation of the main beam of a bridge under maximum temperature variation is 10 mm as the allowance value of engineering design, the wall thickness of the rubber sleeve for this joint should not be less than 40 mm. At last, on the basis of experimental research and theoretical analysis, the formulas of radial stiffness and flexural stiffness are fitted; it can be used as reference for practical engineering application, or for formulation of relevant specifications.
