• Abstract:
  The behavior of Reinforced Concrete Box Culverts under varying backfill, compaction, and traffic loads is not clearly understood. The design rules used at present are mostly empirical and do not allow for the effects of Soil-Culvert interaction. In order to have a better understanding of the field behavior of these culverts, in another research study at the Texas Transportation Institute, an 8 x 8 RC box culvert will be instrumented with earth pressure cells and strain gages The purpose of the study presented in this report is to perform prediction analyses of the behavior of this 8' x 8' culvert, using the finite element computer program, SSTIPN so that the analytical results can be correlated with field observations whenever these become available. In this preliminary study, foundation and backfill materials from the culvert site were used to prepare samples in the laboratory at varying compaction conditions and a number of triaxial tests were performed. Using these nonlinear stress-strain data the backfill and foundation soils around the culvert were stimulated in the computer analyses. The culvert was represented in the analyses by a series of beam elements connected at the common nodes. The backfill placement is simulated by an incremental loading analysis procedure.
