Finite Element Analysis of Centrifuged Concrete Culverts

摘要

The objective of this study was to develop an improved design tool to better predict the soil-structure interaction of underground protective structures using finite element analysis and centrifuge modeling technology. This study shows that the results obtained from an existing finite element computer code, CANDE, and actual centrifuge behavior is quite favorable. Two soil models, a linear model and Duncan's hyperbolic model, were used to show the influence of constitutive relationships on the overall response of the system.
