SOIL-STEEL STRUCTURES AND THE CANADIAN HIGHWAY BRIDGE DESIGN CODE

The aims of this paper are to: review the historic design methods used for soil-steel structures, provide a detailed description of the philosophies used in the CHBDC and AISI (American Iron and Steel Institute) methods, including a description of the critical differences between the methods, and report on a comparison of design results using the 2 methods. In order to compare design results from the 2 methods, a range of structure shapes and sizes were evaluated for numerous depths of cover. The study was limited to the 152 mm x 51 mm corrugation profile. Assumptions were required such that the comparison of methods using different design philosophies (working stress, limit states) are realistic. In general, the CHBDC results in more liberal designs for shallow depths of cover and more conservative designs for large depths of cover. However, the differences between the methods compared are relatively small for the shorter span structures under mid-range depths of cover combined with normal highway loading.
