• Abstract:
  The design criteria for reinforced box culverts currently used are primarily empirical in nature, and do not allow for the effects of soil-structure interaction. These effects have been shown to make a considerable difference in certain situations. In order to have a better understanding of the field behavior of R.C. box culverts, in another research study, the Texas Transportation Institute is studying the behavior of an instrumented 8' x 8' R.C. box culvert. The purpose of the study presented herein is to perform prediction analyses of the behavior of this 8' x 8' box culvert under traffic loads using a finite element method computer program. In this study, soil properties determined from laboratory tests of soil samples taken at the site were used to determine the stress-strain parameters for use in the computer analyses. The culvert was represented in the analyses by a series of beam elements connected at common nodes. An incremental analysis was used to represent placement of backfill materials.
