CANDE is a special-purpose, 2D finite element computer program developed for the structural design and analysis of soil bridges, buried culverts and underground structures. CANDE is applicable to all cross-sectional shapes and materials including corrugated metal, reinforced concrete and thermoplastics.
First introduced in 1976 under sponsorship of the Federal Highway Administration (FHWA), CANDE's capabilities have steadily grown over the years. In 2005, the American Association of State Highway Officials (AASHTO) sponsored additional enhancements in the version called CANDE-2007, which is maintained by the Transportation Research Board (TRB) . In 2011, AASHTO/TRB sponsored more upgrades producing the official AASHTO/TRB version called CANDE-2007 with 2011 upgrade.
Since 2011, several industries and institutions have sponsored new modeling capabilities that are now freely available in the latest version called CANDE-2022. Also, the 2022 CANDE Tool Box, a companion program useful for load rating, is freely available to download.
Detailed information is provided in the followings links along with directions for downloading free copies of the programs.
Complete documentation of the CANDE program is contained within the free download software and includes, User Manual with Graphical User Interface, Solutions and Formulations Manual, and Tutorial of Applications.
For those interested in the history of CANDE's development including government sponsors, research institutions and individual developers, the following two links provide a complete background.
