Analysis and design of box culverts

by Abdel-Haq, Ali H.

Abstract (Summary)
Box culvert problems are a complicated example of soil structure interaction where the relative stiffness between the backfill soil and the culvert materials is a critical factor in the load carrying capacity of culverts. Duncan et al proposed an equation for the design of this class of structures. This equation doesn't take into consideration the soil structure interaction phenomena. A modified form of the above equation, which is presented here, with an allowance for the soil properties and culvert stiffness provides a better agreement with the finite element solution. Furthermore, the presence of PCC relieving slabs and their action in transfering live loads is analyzed and another better agreement with the finite element method is obtained. A sophisticated computer program called SEQCON is used to verify the results obtained from CANDE. The results of both programs are compared with an experimental data on a Lane Steel Culvert.
