“…While nonlinear spring elements are often used to model soil-structure interaction, the FEA software allowed only for linear elastic spring elements in the natural frequency with load stiffening analysis. Consequently, the National Cooperative Highway Research Program (NCHRP) curves for earth pressure coefficient versus relative wall displacement, as presented by Civjan [18] were approximated with a linear fit to the initial slope of passive pressure development. Since the backfill soil properties are unknown, the linear slope approximations for loose and dense sand were averaged.…”

“…In this regard, Civjan, et al [5], Nam and Park [6], and Park and Nam [7] defined the passive soil-pressure changes by conducting long-term field measurements on IABs. Ahn, et al [8] analytically defined the passive earth pressure using long-term thermal expansion of the pre-stressed concrete (PSC) girder in the IAB.…”

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.

“…The parametric study establishes the importance of each parameter and investigates the influence of key parameters on the bridge response. Parametric studies [3][4][5][6] with a limited number of parameters have been performed; however, the present study evaluates bridges with longer lengths and pile supports in clay or sand. Based on a preliminary analysis, five key parameters were selected to cover the range of common IAB geometries.…”
